UITextField para el número de teléfono

Me preguntaba cómo puedo formatear el campo de texto que estoy usando para un número de teléfono (es decir, como la página “Agregar nuevo contacto” en el iPhone. Cuando ingreso un nuevo teléfono móvil, por ejemplo, 1236890987, lo formatea como (123) ) 689-0987.) Ya tengo el teclado configurado como el teclado numérico.

Aquí está mi solución … ¡funciona genial! Formatea el número de teléfono en tiempo real. Nota: Esto es para números de teléfono de 10 dígitos. Y actualmente se formatea automáticamente como (xxx) xxx-xxxx .. retoque para su deleite de corazones.

Primero, en su shouldChangeCharactersInRange , desea reunir toda la cadena para el campo de texto del teléfono y pasarla a la función de validación / formateo.

 - (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; } 

Y aquí es donde el número de teléfono está formateado. La expresión regular probablemente podría limpiarse un poco. Pero he probado este código por un tiempo y parece pasar todas las campanas. Observe que también usamos esta función para eliminar un número en el número de teléfono. Funciona un poco más fácil aquí porque ya hemos eliminado todos los demás dígitos.

  -(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; } 

Así es como puedes hacerlo en 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 } }

 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 } } 

He estado luchando con esto por un par de horas, esto es lo que tengo:

 - (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 alguien pueda contribuir.

Debajo la función impone el formato (999)333-5555 en 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 } } 

Aquí está mi opinión. Lo cual es similar a lo que hace Apple en la aplicación Teléfono y Contactos (al menos cuando su región está configurada en EE. UU., No estoy seguro si el comportamiento cambia por región).

Estaba específicamente interesado en formatear hasta 1 (123) 123-1234 y admitir números más largos sin formato. También hay un error al verificar range.length == 1 (para borrar / retroceder) en las otras soluciones que impide que un usuario seleccione toda la cadena o parte de ella y presionando la tecla borrar / retroceder, esto soluciona esa situación.

Hay algunos comportamientos extraños que ocurren cuando comienza a seleccionar un rango en el medio y edita, donde el cursor siempre termina al final de la cadena debido a la configuración del valor de los campos de texto. No estoy seguro de cómo volver a colocar el cursor en un UITextField , supongo que Apple está utilizando un UITextView en las aplicaciones Contactos y Teléfono, ya que mantienen la posición del cursor mientras hacen este formateo en línea, ¡parecen manejar todos los pequeños matices! Ojalá nos dieran esto de la caja.

 - (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; } 

Esta solución funciona muy bien para los números de América del Norte sin el prefijo de marcación internacional (+1) y sin extensión. El número se formateará como “(212) 555-1234”. Pre-escribirá el “)” y el “-“, pero también se eliminará correctamente.

Aquí está el -textField:shouldChangeCharactersInRange:replacementString que su delegado de campo de texto debe 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; }

Funcionó excelente para mí, espero que también funcione para ti 🙂

Puede agregar un número de teléfono como 000-000-0000 (10 dígitos). Por favor, consulte este código.

Swift 4 (y sin NSString)

para el formato + X (XXX) XXX-XXXX o + X (XXX) XXX-XX-XX Actualizado y ligeramente

Puede llamar a este método cada vez que necesite actualizar su 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 } } 

Ejemplo:

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

Lamentablemente, tienes que hacerlo tú mismo. La aplicación de contacto usa API no documentadas. Por alguna razón, adjuntar formateadores de entrada a los campos de texto no está expuesto en el iPhone de la misma manera que en la Mac. Siéntase libre de presentar un informe de error de mejora de características.

Con suerte, lo que voy a decir será útil para la progtwigción de nuevas personas en iOS, como lo soy yo. Hice lo que sugieren zingle-dingle (¡muchas gracias!). Para ayudar a los nuevos, el código más lo que voy a enumerar podría ayudarte. 1. tiene que agregar el UITextFieldDelegate en el archivo de encabezado. 2. El UITextField debe vincular al delegado con la vista, en mi caso, el UIViewController, que es el archivo de encabezado. 3. UITextField debe ser instalado, es decir, yourtextfile.delegate = self, en el archivo “.m”.

Aquí está mi código Swift 2 ligeramente localizado desde la perspectiva del Reino Unido.

Formateará:

+11234567890 como +1 (123) 456 7890

+33123456789 como +33 1 23 45 67 89

+441234123456 como +44 1234 123456 (esto se ha localizado adicionalmente como 01234 123456) porque no necesito ver el código de país para los números del Reino Unido.

Llame de la siguiente manera:

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

Si tiene otros códigos de país y formatos o mejoras en el código, hágamelo saber.

Disfrutar.

Respuesta actualizada de “Unidad de iOS” para Swift 3 con 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 } 

tienes que hacer esto manualmente tome una notificación de textField y verifique la longitud del texto del campo y formatéelo según el país. si hay algún problema, házmelo saber. He hecho esto

Tengo una solución para esto pero está teniendo algún inconveniente, vea si puede modificarlo y usarlo. Al usar esto puede lograr restringir el número de teléfono a 10 dígitos y formatearlo según el formato de EE. UU.

 #define MAX_LENGTH 10 

Implementarlo en UITextField Método delegado

 - (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; } }

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

Ejemplo

 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.

O

 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) } }
