UITextField para número de telefone

Eu estava querendo saber como eu posso formatar o textField que estou usando para um número de telefone (ou seja, como a página “Adicionar novo contato” no iPhone. Quando eu entro em um novo celular, por exemplo, 1236890987 ele formata como ) 689-0987.) Eu já tenho o teclado definido como o teclado numérico.

Aqui está a minha solução .. funciona muito bem! Formata o número do telefone em tempo real. Nota: Isto é para números de telefone de 10 dígitos. E atualmente ele auto formata como (xxx) xxx-xxxx .. tweak para seus corações prazer.

Primeiro no seu shouldChangeCharactersInRange você deseja reunir toda a string para o campo de texto do telefone e passá-lo para a function de validação / formatação.

 - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { NSString* totalString = [NSString stringWithFormat:@"%@%@",textField.text,string]; // if it's the phone number textfield format it. if(textField.tag==102 ) { if (range.length == 1) { // Delete button was hit.. so tell the method to delete the last char. textField.text = [self formatPhoneNumber:totalString deleteLastChar:YES]; } else { textField.text = [self formatPhoneNumber:totalString deleteLastChar:NO ]; } return false; } return YES; } 

E aqui é onde o número de telefone é formatado. O regex provavelmente poderia ser limpo um pouco. Mas eu testei esse código por um tempo e parece passar todos os sinos. Observe que também usamos essa function para excluir um número no número de telefone. Funciona um pouco mais fácil aqui porque nós já retiramos todos os outros dígitos não.

  -(NSString*) formatPhoneNumber:(NSString*) simpleNumber deleteLastChar:(BOOL)deleteLastChar { if(simpleNumber.length==0) return @""; // use regex to remove non-digits(including spaces) so we are left with just the numbers NSError *error = NULL; NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"[\\s-\\(\\)]" options:NSRegularExpressionCaseInsensitive error:&error]; simpleNumber = [regex stringByReplacingMatchesInString:simpleNumber options:0 range:NSMakeRange(0, [simpleNumber length]) withTemplate:@""]; // check if the number is to long if(simpleNumber.length>10) { // remove last extra chars. simpleNumber = [simpleNumber substringToIndex:10]; } if(deleteLastChar) { // should we delete the last digit? simpleNumber = [simpleNumber substringToIndex:[simpleNumber length] - 1]; } // 123 456 7890 // format the number.. if it's less then 7 digits.. then use this regex. if(simpleNumber.length<7) simpleNumber = [simpleNumber stringByReplacingOccurrencesOfString:@"(\\d{3})(\\d+)" withString:@"($1) $2" options:NSRegularExpressionSearch range:NSMakeRange(0, [simpleNumber length])]; else // else do this one.. simpleNumber = [simpleNumber stringByReplacingOccurrencesOfString:@"(\\d{3})(\\d{3})(\\d+)" withString:@"($1) $2-$3" options:NSRegularExpressionSearch range:NSMakeRange(0, [simpleNumber length])]; return simpleNumber; } 

Veja como você pode fazer isso no Swift:

 func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool { if (textField == phoneTextField) { let newString = (textField.text! as NSString).stringByReplacingCharactersInRange(range, withString: string) let components = newString.componentsSeparatedByCharactersInSet(NSCharacterSet.decimalDigitCharacterSet().invertedSet) let decimalString = components.joinWithSeparator("") as NSString let length = decimalString.length let hasLeadingOne = length > 0 && decimalString.characterAtIndex(0) == (1 as unichar) if length == 0 || (length > 10 && !hasLeadingOne) || length > 11 { let newLength = (textField.text! as NSString).length + (string as NSString).length - range.length as Int return (newLength > 10) ? false : true } var index = 0 as Int let formattedString = NSMutableString() if hasLeadingOne { formattedString.appendString("1 ") index += 1 } if (length - index) > 3 { let areaCode = decimalString.substringWithRange(NSMakeRange(index, 3)) formattedString.appendFormat("(%@)", areaCode) index += 3 } if length - index > 3 { let prefix = decimalString.substringWithRange(NSMakeRange(index, 3)) formattedString.appendFormat("%@-", prefix) index += 3 } let remainder = decimalString.substringFromIndex(index) formattedString.appendString(remainder) textField.text = formattedString as String return false } else { return true } } 

Resposta atualizada do Vikzilla para o Swift 3:

 func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool { if textField == phoneTextField { let newString = (textField.text! as NSString).replacingCharacters(in: range, with: string) let components = (newString as NSString).components(separatedBy: NSCharacterSet.decimalDigits.inverted) let decimalString = components.joined(separator: "") as NSString let length = decimalString.length let hasLeadingOne = length > 0 && decimalString.character(at: 0) == (1 as unichar) if length == 0 || (length > 10 && !hasLeadingOne) || length > 11 { let newLength = (textField.text! as NSString).length + (string as NSString).length - range.length as Int return (newLength > 10) ? false : true } var index = 0 as Int let formattedString = NSMutableString() if hasLeadingOne { formattedString.append("1 ") index += 1 } if (length - index) > 3 { let areaCode = decimalString.substring(with: NSMakeRange(index, 3)) formattedString.appendFormat("(%@)", areaCode) index += 3 } if length - index > 3 { let prefix = decimalString.substring(with: NSMakeRange(index, 3)) formattedString.appendFormat("%@-", prefix) index += 3 } let remainder = decimalString.substring(from: index) formattedString.append(remainder) textField.text = formattedString as String return false } else { return true } } 

Eu tenho lutado com isso por um par de horas, aqui está o que eu tenho:

 - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { NSUInteger currentLength = textField.text.length; NSCharacterSet *numbers = [NSCharacterSet decimalDigitCharacterSet]; if (range.length == 1) { return YES; } if ([numbers characterIsMember:[string characterAtIndex:0]]) { if ( currentLength == 3 ) { if (range.length != 1) { NSString *firstThreeDigits = [textField.text substringWithRange:NSMakeRange(0, 3)]; NSString *updatedText; if ([string isEqualToString:@"-"]) { updatedText = [NSString stringWithFormat:@"%@",firstThreeDigits]; } else { updatedText = [NSString stringWithFormat:@"%@-",firstThreeDigits]; } [textField setText:updatedText]; } } else if ( currentLength > 3 && currentLength < 8 ) { if ( range.length != 1 ) { NSString *firstThree = [textField.text substringWithRange:NSMakeRange(0, 3)]; NSString *dash = [textField.text substringWithRange:NSMakeRange(3, 1)]; NSUInteger newLenght = range.location - 4; NSString *nextDigits = [textField.text substringWithRange:NSMakeRange(4, newLenght)]; NSString *updatedText = [NSString stringWithFormat:@"%@%@%@",firstThree,dash,nextDigits]; [textField setText:updatedText]; } } else if ( currentLength == 8 ) { if ( range.length != 1 ) { NSString *areaCode = [textField.text substringWithRange:NSMakeRange(0, 3)]; NSString *firstThree = [textField.text substringWithRange:NSMakeRange(4, 3)]; NSString *nextDigit = [textField.text substringWithRange:NSMakeRange(7, 1)]; [textField setText:[NSString stringWithFormat:@"(%@) %@-%@",areaCode,firstThree,nextDigit]]; } } } else { return NO; } return YES; } 

Espero que alguém possa contribuir.

Abaixo da function aplica-se o formato (999)333-5555 no textField:

Swift 3:

 func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool { if (textField == self.phone){ let newString = (textField.text! as NSString).replacingCharacters(in: range, with: string) let components = newString.components(separatedBy: NSCharacterSet.decimalDigits.inverted) let decimalString = components.joined(separator: "") as NSString let length = decimalString.length let hasLeadingOne = length > 0 && decimalString.character(at: 0) == (1 as unichar) if length == 0 || (length > 10 && !hasLeadingOne) || length > 11 { let newLength = (textField.text! as NSString).length + (string as NSString).length - range.length as Int return (newLength > 10) ? false : true } var index = 0 as Int let formattedString = NSMutableString() if hasLeadingOne { formattedString.append("1 ") index += 1 } if (length - index) > 3 { let areaCode = decimalString.substring(with: NSMakeRange(index, 3)) formattedString.appendFormat("(%@)", areaCode) index += 3 } if length - index > 3 { let prefix = decimalString.substring(with: NSMakeRange(index, 3)) formattedString.appendFormat("%@-", prefix) index += 3 } let remainder = decimalString.substring(from: index) formattedString.append(remainder) textField.text = formattedString as String return false } else { return true } } 

Aqui está a minha opinião. O que é parecido com o que a Apple faz no aplicativo Telefone e Contatos (pelo menos quando sua região está definida como EUA, não tenho certeza se o comportamento muda por região).

Eu estava especificamente interessado em formatar até 1 (123) 123-1234 e suportar números mais longos sem formatação. Há também um bug em apenas verificar range.length == 1 (para delete / backspace) nas outras soluções que impedem que um usuário selecione toda a string ou parte dela e pressiona a tecla delete / backspace, isso corrige essa situação.

Existem alguns comportamentos estranhos que ocorrem quando você começa a selecionar um intervalo no meio e edita, onde o cursor sempre termina no final da string devido à configuração do valor dos campos de texto. Não sei como reposicionar o cursor em um UITextField , presumo que a Apple esteja realmente usando um UITextView nos aplicativos Contatos e Telefone, pois eles mantêm a posição do cursor enquanto fazem essa formatação em linha, eles parecem lidar com todas as pequenas nuances! Eu gostaria que eles nos dessem para fora da checkbox.

 - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { NSMutableString *newString = [NSMutableString stringWithString:textField.text]; [newString replaceCharactersInRange:range withString:string]; NSString *phoneNumberString = [self formattedPhoneNumber:newString]; if (range.length >= 1) { // backspace/delete if (phoneNumberString.length > 1) { // the way we format the number it is possible that when the user presses backspace they are not deleting the last number // in the string, so we need to check if the last character is a number, if it isn't we need to delete everything after the // last number in the string unichar lastChar = [phoneNumberString characterAtIndex:phoneNumberString.length-1]; NSCharacterSet *numberCharacterSet = [NSCharacterSet characterSetWithCharactersInString:@"1234567890#*"]; if (![numberCharacterSet characterIsMember:lastChar]) { NSRange numberRange = [phoneNumberString rangeOfCharacterFromSet:numberCharacterSet options:NSBackwardsSearch]; phoneNumberString = [phoneNumberString substringToIndex:numberRange.location+1]; } } } textField.text = phoneNumberString; return NO; } - (NSString *)formattedPhoneNumber:(NSString *)string { NSString *formattedPhoneNumber = @""; NSCharacterSet *numberCharacterSet = [NSCharacterSet characterSetWithCharactersInString:@"1234567890#*+"]; NSRange pauseRange = [string rangeOfString:@","]; NSRange waitRange = [string rangeOfString:@";"]; NSString *numberStringToFormat = nil; NSString *numberStringToAppend = @""; if (pauseRange.location != NSNotFound || waitRange.location != NSNotFound) { NSString *choppedString = [string substringToIndex:MIN(pauseRange.location, waitRange.location)]; numberStringToFormat = [[choppedString componentsSeparatedByCharactersInSet:[numberCharacterSet invertedSet]] componentsJoinedByString:@""]; numberStringToAppend = [string substringFromIndex:MIN(pauseRange.location, waitRange.location)]; } else { numberStringToFormat = [[string componentsSeparatedByCharactersInSet:[numberCharacterSet invertedSet]] componentsJoinedByString:@""]; } if ([numberStringToFormat hasPrefix:@"0"] || [numberStringToFormat hasPrefix:@"11"]) { // numbers starting with 0 and 11 should not be formatted formattedPhoneNumber = numberStringToFormat; } else if ([numberStringToFormat hasPrefix:@"1"]) { if (numberStringToFormat.length <= 1) { // 1 formattedPhoneNumber = numberStringToFormat; } else if (numberStringToFormat.length <= 4) { // 1 (234) NSString *areaCode = [numberStringToFormat substringFromIndex:1]; if (areaCode.length < 3) { formattedPhoneNumber = [NSString stringWithFormat:@"1 (%@", [numberStringToFormat substringFromIndex:1]]; // 1 (XXX) } else { formattedPhoneNumber = [NSString stringWithFormat:@"1 (%@) ", [numberStringToFormat substringFromIndex:1]]; // 1 (XXX) } } else if (numberStringToFormat.length <= 7) { // 1 (234) 123 formattedPhoneNumber = [NSString stringWithFormat:@"1 (%@) %@", [numberStringToFormat substringWithRange:NSMakeRange(1, 3)], //1 (XXX) 123 [numberStringToFormat substringFromIndex:4]]; // 1 (234) XXX } else if (numberStringToFormat.length <= 11) { // 1 (123) 123-1234 formattedPhoneNumber = [NSString stringWithFormat:@"1 (%@) %@-%@", [numberStringToFormat substringWithRange:NSMakeRange(1, 3)], //1 (XXX) 123 [numberStringToFormat substringWithRange:NSMakeRange(4, 3)], //1 (234) XXX-1234 [numberStringToFormat substringFromIndex:7]]; // 1 (234) 123-XXXX } else { // 1123456789012.... formattedPhoneNumber = numberStringToFormat; } } else { if (numberStringToFormat.length <= 3) { // 123 formattedPhoneNumber = numberStringToFormat; } else if (numberStringToFormat.length <= 7) { // 123-1234 formattedPhoneNumber = [NSString stringWithFormat:@"%@-%@", [numberStringToFormat substringToIndex:3], // XXX-1234 [numberStringToFormat substringFromIndex:3]]; // 123-XXXX } else if (numberStringToFormat.length <= 10) { // (123) 123-1234 formattedPhoneNumber = [NSString stringWithFormat:@"(%@) %@-%@", [numberStringToFormat substringToIndex:3], // (XXX) 123-1234 [numberStringToFormat substringWithRange:NSMakeRange(3, 3)], // (123) XXX-1234 [numberStringToFormat substringFromIndex:6]]; // (123) 123-XXXX } else { // 123456789012.... formattedPhoneNumber = numberStringToFormat; } } if (numberStringToAppend.length > 0) { formattedPhoneNumber = [NSString stringWithFormat:@"%@%@", formattedPhoneNumber, numberStringToAppend]; } return formattedPhoneNumber; } 

Essa solução funciona muito bem para números norte-americanos sem o prefixo de discagem internacional (+1) e sem extensão. O número será formatado como “(212) 555-1234”. Ele irá pré-digitar o “)” e o “-“, mas também serão excluídos corretamente.

Aqui está o -textField:shouldChangeCharactersInRange:replacementString que o delegado de campo de texto deve implementar:

 - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { if (textField == self.myPhoneTextField) { NSString *newText = [textField.text stringByReplacingCharactersInRange:range withString:string]; BOOL deleting = [newText length] < [textField.text length]; NSString *stripppedNumber = [newText stringByReplacingOccurrencesOfString:@"[^0-9]" withString:@"" options:NSRegularExpressionSearch range:NSMakeRange(0, [newText length])]; NSUInteger digits = [stripppedNumber length]; if (digits > 10) stripppedNumber = [stripppedNumber substringToIndex:10]; UITextRange *selectedRange = [textField selectedTextRange]; NSInteger oldLength = [textField.text length]; if (digits == 0) textField.text = @""; else if (digits < 3 || (digits == 3 && deleting)) textField.text = [NSString stringWithFormat:@"(%@", stripppedNumber]; else if (digits < 6 || (digits == 6 && deleting)) textField.text = [NSString stringWithFormat:@"(%@) %@", [stripppedNumber substringToIndex:3], [stripppedNumber substringFromIndex:3]]; else textField.text = [NSString stringWithFormat:@"(%@) %@-%@", [stripppedNumber substringToIndex:3], [stripppedNumber substringWithRange:NSMakeRange(3, 3)], [stripppedNumber substringFromIndex:6]]; UITextPosition *newPosition = [textField positionFromPosition:selectedRange.start offset:[textField.text length] - oldLength]; UITextRange *newRange = [textField textRangeFromPosition:newPosition toPosition:newPosition]; [textField setSelectedTextRange:newRange]; return NO; } return YES; } 

Resposta atualizada para o Swift 2.0 do Vikzilla:

Trabalhou excelente para mim, espero que funcione para você também 🙂

Você pode adicionar um número de telefone como 000-000-0000 (10 dígitos). Por favor, consulte este código.

 - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { if (textField==Phone_TXT) { if (range.location == 12) { return NO; } // Backspace if ([string length] == 0) return YES; if ((range.location == 3) || (range.location == 7)) { NSString *str = [NSString stringWithFormat:@"%@-",textField.text]; textField.text = str; } return YES; } } 

Minha solução para o formato + X (XXX) XXX-XXXX. (RÁPIDO)

 func textFieldDidBeginEditing(textField: UITextField) { if (textField == self.mobileField) { textField.text = "+" } } func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool { if (textField == self.mobileField) { let newString = (textField.text! as NSString).stringByReplacingCharactersInRange(range, withString: string) if (newString.characters.count < textField.text?.characters.count && newString.characters.count >= 1) { return true // return true for backspace to work } else if (newString.characters.count < 1) { return false; // deleting "+" makes no sence } if (newString.characters.count > 17 ) { return false; } let components = newString.componentsSeparatedByCharactersInSet(NSCharacterSet.decimalDigitCharacterSet().invertedSet) let decimalString = components.joinWithSeparator("") as NSString let length = decimalString.length var index = 0 let formattedString = NSMutableString() formattedString.appendString("+") if (length >= 1) { let countryCode = decimalString.substringWithRange(NSMakeRange(0, 1)) formattedString.appendString(countryCode) index += 1 } if (length > 1) { var rangeLength = 3 if (length < 4) { rangeLength = length - 1 } let operatorCode = decimalString.substringWithRange(NSMakeRange(1, rangeLength)) formattedString.appendFormat(" (%@) ", operatorCode) index += operatorCode.characters.count } if (length > 4) { var rangeLength = 3 if (length < 7) { rangeLength = length - 4 } let prefix = decimalString.substringWithRange(NSMakeRange(4, rangeLength)) formattedString.appendFormat("%@-", prefix) index += prefix.characters.count } if (index < length) { let remainder = decimalString.substringFromIndex(index) formattedString.appendString(remainder) } textField.text = formattedString as String if (newString.characters.count == 17) { textField.resignFirstResponder() } return false } return true } 

Swift 4 (e sem NSString)

para o formato + X (XXX) XXX-XXXX ou + X (XXX) XXX-XX-XX Atualizado e ligeiramente

 class ViewController: UIViewController, UITextFieldDelegate { var myPhoneNumber = String() @IBOutlet weak var phoneTextField: UITextField! override func viewDidLoad() { super.viewDidLoad() phoneTextField.delegate = self phoneTextField.keyboardType = .phonePad } func textFieldDidBeginEditing(_ textField: UITextField) { if (textField == self.phoneTextField) && textField.text == ""{ textField.text = "+7(" //your country code default } } func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool { if textField == phoneTextField { let res = phoneMask(phoneTextField: phoneTextField, textField: textField, range, string) myPhoneNumber = res.phoneNumber != "" ? "+\(res.phoneNumber)" : "" print("Phone - \(myPhoneNumber) MaskPhone=\(res.maskPhoneNumber)") if (res.phoneNumber.count == 11) || (res.phoneNumber.count == 0) { //phone number entered or completely cleared print("EDIT END: Phone = \(myPhoneNumber) MaskPhone = \(res.maskPhoneNumber)") } return res.result } return true } } extension UITextFieldDelegate { func phoneMask(phoneTextField: UITextField, textField: UITextField, _ range: NSRange, _ string: String) -> (result: Bool, phoneNumber: String, maskPhoneNumber: String) { let oldString = textField.text! let newString = oldString.replacingCharacters(in: Range(range, in: oldString)!, with: string) //in numString only Numeric characters let components = newString.components(separatedBy: CharacterSet.decimalDigits.inverted) let numString = components.joined(separator: "") let length = numString.count let maxCharInPhone = 11 if newString.count < oldString.count { //backspace to work if newString.count <= 2 { //if now "+7(" and push backspace phoneTextField.text = "" return (false, "", "") } else { return (true, numString, newString) //will not in the process backspace } } if length > maxCharInPhone { // input is complete, do not add characters return (false, numString, newString) } var indexStart, indexEnd: String.Index var maskString = "", template = "" var endOffset = 0 if newString == "+" { // allow add "+" if first Char maskString += "+" } //format +X(XXX)XXX-XXXX if length > 0 { maskString += "+" indexStart = numString.index(numString.startIndex, offsetBy: 0) indexEnd = numString.index(numString.startIndex, offsetBy: 1) maskString += String(numString[indexStart.. 1 { endOffset = 4 template = ")" if length < 4 { endOffset = length template = "" } indexStart = numString.index(numString.startIndex, offsetBy: 1) indexEnd = numString.index(numString.startIndex, offsetBy: endOffset) maskString += String(numString[indexStart.. 4 { endOffset = 7 template = "-" if length < 7 { endOffset = length template = "" } indexStart = numString.index(numString.startIndex, offsetBy: 4) indexEnd = numString.index(numString.startIndex, offsetBy: endOffset) maskString += String(numString[indexStart.. if need uncoment // nIndex = 9 // // if length > 7 { // endOffset = 9 // template = "-" // if length < 9 { // endOffset = length // template = "" // } // indexStart = numString.index(numString.startIndex, offsetBy: 7) // indexEnd = numString.index(numString.startIndex, offsetBy: endOffset) // maskString += String(numString[indexStart.. nIndex { indexStart = numString.index(numString.startIndex, offsetBy: nIndex) indexEnd = numString.index(numString.startIndex, offsetBy: length) maskString += String(numString[indexStart.. 

Você pode chamar este método sempre que precisar atualizar seu textField:

 extension String { func applyPatternOnNumbers(pattern: String, replacmentCharacter: Character) -> String { var pureNumber = self.replacingOccurrences( of: "[^0-9]", with: "", options: .regularExpression) for index in 0 ..< pattern.count { guard index < pureNumber.count else { return pureNumber } let stringIndex = String.Index(encodedOffset: index) let patternCharacter = pattern[stringIndex] guard patternCharacter != replacmentCharacter else { continue } pureNumber.insert(patternCharacter, at: stringIndex) } return pureNumber } } 

Exemplo:

  guard let text = textField.text else { return } textField.text = text.applyPatternOnNumbers(pattern: "+# (###) ###-####", replacmentCharacter: "#") 

Infelizmente, você tem que fazer isso sozinho. O aplicativo de contato usa APIs não documentadas. Por algum motivo, a anexação de formatadores de input a campos de texto não é exposta no iPhone da maneira como está no Mac. Sinta-se à vontade para registrar um relatório de bug de melhoria de resources.

Espero que, o que eu vou dizer, será útil para novas pessoas programando no iOS, como eu sou. Eu fiz o que o zingle-dingle sugere (muito obrigado!). Para ajudar os novos, o código mais o que vou listar poderia ajudá-lo. 1. você tem que adicionar o UITextFieldDelegate no arquivo de header. 2. O UITextField deve ligar o delegado com a view, no meu caso o UIViewController, que é o arquivo de header. 3. o UITextField deve ser instatiated, isto é, yourtextfile.delegate = self, no arquivo “.m”.

Aqui está o meu código Swift 2 de um pouco localizado do ponto de vista do Reino Unido.

Ele irá formatar:

+11234567890 como +1 (123) 456 7890

+33123456789 como +33 1 23 45 67 89

+441234123456 como +44 1234 123456 (isso foi localizado ainda como 01234 123456) porque eu não preciso ver o código do país para os números do Reino Unido.

Ligue da seguinte forma:

 initInternationalPhoneFormats() //this just needs to be done once var formattedNo = formatInternationalPhoneNo("+11234567890") 

Se você tiver outros códigos de países e formatos ou melhorias no código, por favor me avise.

Resposta atualizada de “Unidade iOS” para o Swift 3 com o formato + X (XXX) XXX-XXXX:

 func textFieldDidBeginEditing(_ textField: UITextField) { if (textField == self.phoneTextField) { textField.text = "+" } } func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool { if (textField == self.phoneTextField) { let newString = (textField.text! as NSString).replacingCharacters(in: range, with: string) if (newString.characters.count < (textField.text?.characters.count)! && newString.characters.count >= 1) { return true // return true for backspace to work } else if (newString.characters.count < 1) { return false; // deleting "+" makes no sence } if (newString.characters.count > 17 ) { return false; } let components = newString.components(separatedBy: CharacterSet.decimalDigits.inverted) let decimalString = components.joined(separator: "") as NSString let length = decimalString.length var index = 0 let formattedString = NSMutableString() formattedString.append("+") if (length >= 1) { let countryCode = decimalString.substring(with: NSMakeRange(0, 1)) formattedString.append(countryCode) index += 1 } if (length > 1) { var rangeLength = 3 if (length < 4) { rangeLength = length - 1 } let operatorCode = decimalString.substring(with: NSMakeRange(1, rangeLength)) formattedString.appendFormat(" (%@) ", operatorCode) index += operatorCode.characters.count } if (length > 4) { var rangeLength = 3 if (length < 7) { rangeLength = length - 4 } let prefix = decimalString.substring(with: NSMakeRange(4, rangeLength)) formattedString.appendFormat("%@-", prefix) index += prefix.characters.count } if (index < length) { let remainder = decimalString.substring(from: index) formattedString.append(remainder) } textField.text = formattedString as String if (newString.characters.count == 17) { textField.resignFirstResponder() } return false } return true } 

u have to do to this manually . take a notification of textField and check length of field text and format it according to country. if any problem let me know. I have done this

I have a solution for this but it is having some drawback, see if you can modify and use it. By using this you can achieve both restrict phone number to 10 digit and format it as per US format.

 #define MAX_LENGTH 10 

Implement it in UITextField Delegate method

 - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { NSInteger insertDelta = string.length - range.length; if (PhoneNumber_txt.text.length + insertDelta > MAX_LENGTH) { return NO; // the new string would be longer than MAX_LENGTH } else { range.length = 3; range.location = 3; PhoneNumber_txt.text = [NSString stringWithFormat:@"(%@)%@-%@", [PhoneNumber_txt.text substringToIndex:3], [PhoneNumber_txt.text substringWithRange:range], [PhoneNumber_txt.text substringFromIndex:6]]; return YES; } } 
 - (BOOL) textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { NSCharacterSet* validationSet = [[NSCharacterSet decimalDigitCharacterSet] invertedSet]; NSArray* components = [string componentsSeparatedByCharactersInSet:validationSet]; if ([components count] > 1) { return NO; } NSString* newString = [textField.text stringByReplacingCharactersInRange:range withString:string]; NSArray* validComponents = [newString componentsSeparatedByCharactersInSet:validationSet]; static const int localNumberMaxLength = 7; static const int areaCodeMaxLength = 3; static const int countryCodeMaxLength = 2; newString = [validComponents componentsJoinedByString:@""]; if ([newString length] > localNumberMaxLength + areaCodeMaxLength + countryCodeMaxLength) { return NO; } NSLog(@"new string: %@", newString); NSMutableString* resultString = [NSMutableString string]; NSInteger localNumberLength = MIN([newString length], localNumberMaxLength); if (localNumberLength > 0) { NSString* number = [newString substringFromIndex:(int)[newString length] - localNumberLength]; [resultString appendString:number]; if ([resultString length] > 3) { [resultString insertString:@"-" atIndex:3]; } } if ([newString length] > localNumberMaxLength) { NSInteger areaCodeLength = MIN((int)[newString length] - localNumberMaxLength, areaCodeMaxLength); NSRange areaRange = NSMakeRange((int)[newString length] - localNumberMaxLength - areaCodeLength, areaCodeLength); NSString* area = [newString substringWithRange:areaRange]; area = [NSString stringWithFormat:@"(%@) ",area]; [resultString insertString:area atIndex:0]; } if ([newString length] > localNumberMaxLength + areaCodeMaxLength) { NSInteger countryCodeLength = MIN((int)[newString length] - localNumberMaxLength - areaCodeMaxLength, countryCodeMaxLength); NSRange countryCodeRange = NSMakeRange(0, countryCodeLength); NSString* countryCode = [newString substringWithRange:countryCodeRange]; countryCode = [NSString stringWithFormat:@"+%@ ",countryCode]; [resultString insertString:countryCode atIndex:0]; } textField.text = resultString; return NO; 

}

Here is my solution for 05xx xxx xxxx phone format. At the beginning I set

 phoneTextField.delegate = self phoneTextField.text = "05" // I don't let user to change it. 

It also covers copy/paste cases for cursor position.

Maybe it helps someone for different formats.

 func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool { if range.location == 0 || range.location == 1 { return false } var phone = (textField.text! as NSString).replacingCharacters(in: range, with: string) if phone.length > 13 { return false } phone = phone.replacingOccurrences(of: " ", with: "") if phone.characters.count > 7 { phone.insert(" ", at: phone.index(phone.startIndex, offsetBy: 4)) phone.insert(" ", at: phone.index(phone.startIndex, offsetBy: 8)) } else if phone.characters.count > 4 { phone.insert(" ", at: phone.index(phone.startIndex, offsetBy: 4)) } let text = textField.text let stringToStart = text?.substring(to: (text?.index((text?.startIndex)!, offsetBy: range.location))!) let stringToStartCount = ((stringToStart?.components(separatedBy: " ").count)! > 1) ? (stringToStart?.components(separatedBy: " ").count)!-1 : 0 var cursorIndex = range.location + string.length - stringToStartCount if cursorIndex > 7 { cursorIndex += 2 } else if cursorIndex > 4 { cursorIndex += 1 } textField.text = phone textField.selectedTextRange = textField.textRange(from: textField.position(from: textField.beginningOfDocument, offset: cursorIndex)!, to: textField.position(from: textField.beginningOfDocument, offset: cursorIndex)!) return false } 

You can use this library https://github.com/luximetr/AnyFormatKit

Exemplo

 let textInputController = TextInputController() let textInput = TextInputField() // or TextInputView or any TextInput textInputController.textInput = textInput // setting textInput let formatter = TextInputFormatter(textPattern: "### (###) ###-##-##", prefix: "+12") textInputController.formatter = formatter // setting formatter 

Just set your textField to this textInputController and it will format text with pattern, that you set.

Ou

 let phoneFormatter = TextFormatter(textPattern: "### (###) ###-##-##") phoneFormatter.formattedText(from: "+123456789012") // +12 (345) 678-90-12 

for format full string

objective c solution for +X (XXX) XXX-XXXX format

 - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { if (textField == objCell.txtPhone) { NSString *newString = [textField.text stringByReplacingCharactersInRange:range withString:string]; if (newString.length < ([textField.text length]) && newString.length >= 1) { return true; } else if (newString.length < 1) { return false; } if (newString.length > 15 ) { return false; } NSArray *components =[newString componentsSeparatedByCharactersInSet:[[NSCharacterSet decimalDigitCharacterSet] invertedSet]]; NSString *decimalString = [components componentsJoinedByString:@""]; NSUInteger length = decimalString.length; NSUInteger index = 0; NSMutableString *formattedString=[[NSMutableString alloc] init]; [formattedString appendString:@"+"]; if (length >= 1) { NSString *countryCode = [decimalString substringWithRange:NSMakeRange(0,1)]; [formattedString appendString:countryCode]; index += 1; } if (length > 1) { NSUInteger rangeLength = 3; if (length < 4) { rangeLength = length - 1; } NSString *operatorCode = [decimalString substringWithRange:NSMakeRange(1, rangeLength)]; [formattedString appendFormat:@"(%@)",operatorCode]; index += operatorCode.length; } if (length > 4) { NSUInteger rangeLength = 3; if (length < 7) { rangeLength = length - 4; } NSString *prefix = [decimalString substringWithRange:NSMakeRange(4, rangeLength)]; [formattedString appendFormat:@"%@-",prefix]; index += prefix.length; } if (index < length) { NSString *remainder = [decimalString substringFromIndex:index]; [formattedString appendString:remainder]; } textField.text = formattedString; if (newString.length == 15) { [textField resignFirstResponder]; } contactNumberAdded=decimalString; return false; } return YES; } 

I use this format X (XXX) XXX XX XX it is work in Turkey,

I use it with TableView with Swift 4

 func formatToPhoneNumber(withPhoneTextField: UITextField, tableTextField: UITextField, range: NSRange, string: String) -> Bool { if (tableTextField == withPhoneTextField) { let newString = (tableTextField.text! as NSString).replacingCharacters(in: range, with: string) let components = newString.components(separatedBy: NSCharacterSet.decimalDigits.inverted) let decimalString = components.joined(separator: "") as NSString let length = decimalString.length let hasLeadingOne = length > 0 && decimalString.character(at: 0) == (1 as unichar) if length == 0 || (length > 11 && !hasLeadingOne) || length > 12 { let newLength = (tableTextField.text! as NSString).length + (string as NSString).length - range.length as Int return (newLength > 11) ? false : true } var index = 0 as Int let formattedString = NSMutableString() if hasLeadingOne { formattedString.append("1 ") index += 1 } if (length - index) > 1{ let zeroNumber = decimalString.substring(with: NSMakeRange(index, 1)) formattedString.appendFormat("%@ ", zeroNumber) index += 1 } if (length - index) > 3 { let areaCode = decimalString.substring(with: NSMakeRange(index, 3)) formattedString.appendFormat("(%@) ", areaCode) index += 3 } if length - index > 3 { let prefix = decimalString.substring(with: NSMakeRange(index, 3)) formattedString.appendFormat("%@ ", prefix) index += 3 } if (length - index) > 3{ let prefix = decimalString.substring(with: NSMakeRange(index, 2)) formattedString.appendFormat("%@ ", prefix) index += 2 } let remainder = decimalString.substring(from: index) formattedString.append(remainder) tableTextField.text = formattedString as String return false } else { return true } } 

and you can call this func in

 func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String, indexPath: IndexPath) -> Bool { } 

in any indexPath that your text field in it

for example my textfield in indexPath number 1 so the code will be

 func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String, indexPath: IndexPath) -> Bool { if indexPath.row == 1 { let phoneTextField = textField return formatToPhoneNumber(withPhoneTextField: phoneTextField, tableTextField: textField, range: range, string: string) } }
