UITextField pour numéro de téléphone
Je me demandais comment formater le champ textField que j'utilise pour un numéro de téléphone (par exemple, la page "Ajouter un nouveau contact" de l'iPhone. Lorsque j'entre dans un nouveau téléphone portable, par exemple, il est au format 1236890987 (123 ) 689-0987.) Le clavier est déjà défini comme pavé numérique.
Voici ma solution .. fonctionne très bien! Formate le numéro de téléphone en temps réel. Remarque: Ceci concerne les numéros de téléphone à 10 chiffres. Et actuellement, il le formate automatiquement comme (xxx) xxx-xxxx .. Ajustez à ravir votre coeur.
Tout d'abord, dans votre shouldChangeCharactersInRange, vous souhaitez rassembler la chaîne entière du champ de texte du téléphone et la transmettre à la fonction de validation/formatage.
- (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;
}
Et voici où le numéro de téléphone est formaté. La regex pourrait probablement être nettoyée un peu. Mais j'ai testé ce code pendant un moment et semble passer toutes les cloches. Notez que nous utilisons également cette fonction pour supprimer un numéro du numéro de téléphone. Cela fonctionne un peu plus facilement ici, car nous avons déjà supprimé tous les autres chiffres.
-(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;
}
Voici comment vous pouvez le faire dans Swift 4:
func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool
{
if (textField == phoneTextField) {
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
}
}

Voici ma prise de celui-ci. Ce qui est proche de ce que fait Apple dans l’application Téléphone et Contacts (du moins lorsque votre région est définie sur États-Unis, je ne suis pas sûr si le comportement change par région).
J'étais particulièrement intéressé par le formatage jusqu'à 1 (123) 123-1234 et par la prise en charge de nombres plus longs sans formatage. Il y a aussi un bogue dans la vérification de range.length == 1 (pour delete/backspace) dans les autres solutions qui empêche un utilisateur de sélectionner la chaîne entière ou une partie de celle-ci et en appuyant sur la touche delete/backspace, ce qui résout ce problème.
Certains comportements étranges se produisent lorsque vous commencez à sélectionner une plage au milieu et à modifier, où le curseur se termine toujours à la fin de la chaîne en raison de la définition de la valeur des champs de texte. Je ne suis pas sûr de savoir comment repositionner le curseur dans une UITextField, je suppose que Apple utilise réellement une UITextView dans les applications Contacts et Téléphone, car elles maintiennent la position du curseur tout en effectuant ce formatage en ligne, elles semblent gérer toutes les petites nuances! Je souhaite qu'ils nous donnent juste ceci hors de la boîte.

Cette solution fonctionne parfaitement pour les numéros d'Amérique du Nord sans le préfixe international (+1) et sans extension. Le numéro sera au format "(212) 555-1234". Il va pré-taper le ")" et le "-", mais sera également supprimé correctement.
Voici le -textField:shouldChangeCharactersInRange:replacementString que votre délégué de champ de texte doit implémenter:
- (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;
}
Vous pouvez appeler cette méthode chaque fois que vous devez mettre à jour votre 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
}
}
Exemple:
guard let text = textField.text else { return }
textField.text = text.applyPatternOnNumbers(pattern: "+# (###) ###-####", replacmentCharacter: "#")

Voici mon code Swift 2 légèrement localisé du point de vue du Royaume-Uni.
Il formatera:
+11234567890 as +1 (123) 456 7890
Au +33123456789 au +33 1 23 45 67 89
+441234123456 comme +44 1234 123456 (ceci a été localisé plus loin que 01234 123456) car je n'ai pas besoin de voir l'indicatif de pays pour les numéros britanniques.
Appeler comme suit:
initInternationalPhoneFormats() //this just needs to be done once
var formattedNo = formatInternationalPhoneNo("+11234567890")
Si vous avez d'autres codes de pays et formats ou améliorations du code, veuillez me le faire savoir.
Prendre plaisir.

Vous pouvez utiliser cette bibliothèque https://github.com/luximetr/AnyFormatKit
Exemple
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
Il suffit de définir votre textField sur textInputController pour formater le texte avec le motif que vous avez défini.
Ou
let phoneFormatter = TextFormatter(textPattern: "### (###) ###-##-##")
phoneFormatter.formattedText(from: "+123456789012") // +12 (345) 678-90-12
pour le format chaîne complète
Malheureusement, vous devez le faire vous-même. L'application de contact utilise des API non documentées. Pour une raison quelconque, l’attachement de formateurs d’entrée à des champs de texte n’est pas exposé sur l’iPhone comme sur un Mac. N'hésitez pas à déposer un rapport de bogue d'amélioration de fonctionnalité.
Voici ma solution pour le format de téléphone 05xx xxx xxxx. Au début je mis
phoneTextField.delegate = self
phoneTextField.text = "05" // I don't let user to change it.
Il couvre également les cas de copier/coller pour la position du curseur.
Peut-être que cela aide quelqu'un pour différents formats.

J'espère que ce que je vais dire sera utile pour les nouvelles personnes programmant sur iOS, comme je le suis. J'ai fait ce que zingle-dingle suggère (merci beaucoup!). Pour aider les nouveaux, le code plus ce que je vais énumérer pourrait vous aider ... 1. vous devez ajouter UITextFieldDelegate sur le fichier d'en-tête. 2. UITextField doit lier le délégué à la vue, dans mon cas l'UIViewController, qui est le fichier d'en-tête. 3. UITextField doit être installé, cela signifie que votre_fichier.delegate = self, dans le fichier ".m".
https://github.com/chebur/CHRTextFieldFormatter fonctionne comme un charme.
Copier/coller depuis la page d'utilisation:
- (void)viewDidLoad {
[super viewDidLoad];
self.phoneNumberFormatter = [[CHRTextFieldFormatter alloc] initWithTextField:self.phoneNumberTextField mask:[CHRPhoneNumberMask new]];
self.cardNumberFormatter = [[CHRTextFieldFormatter alloc] initWithTextField:self.cardNumberTextField mask:[CHRCardNumberMask new]];
}
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
if (textField == self.phoneNumberTextField) {
return [self.phoneNumberFormatter textField:textField shouldChangeCharactersInRange:range replacementString:string];
} else if (textField == self.cardNumberTextField) {
return [self.cardNumberFormatter textField:textField shouldChangeCharactersInRange:range replacementString:string];
} else {
return YES;
}
}
Aussi rapide:
override func viewDidLoad() {
super.viewDidLoad()
self.phoneNumber.delegate = self
self.phoneNumberFormatter = CHRTextFieldFormatter(textField: self.phoneNumber, mask:CHRPhoneNumberMask())
}
func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {
if textField == self.phoneNumber {
return self.phoneNumberFormatter.textField(textField, shouldChangeCharactersInRange: range, replacementString: string)
}
return true
}

vous devez faire cela manuellement. prenez une notification de textField et vérifiez la longueur du champ text et formatez-le en fonction du pays . en cas de problème, faites le moi savoir Je l'ai fait
- (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;
}
J'ai une solution à cela, mais il y a un inconvénient, voyez si vous pouvez le modifier et l'utiliser. En utilisant cela, vous pouvez limiter le numéro de téléphone à 10 chiffres et le formater selon le format américain.
#define MAX_LENGTH 10
Implémentez-le dans la méthode UITextField Delegate
- (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;
}
}
C'est ma solution en utilisant Swift 4 pour formater un certain nombre de type (123) 689-0987
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
guard let currentText:String = textField.text else {return true}
if string.rangeOfCharacter(from: CharacterSet.decimalDigits.inverted) != nil { return false }
let newCount:Int = currentText.count + string.count - range.length
let addingCharacter:Bool = range.length <= 0
if(newCount == 1){
textField.text = addingCharacter ? currentText + "(\(string)" : String(currentText.dropLast(2))
return false
}else if(newCount == 5){
textField.text = addingCharacter ? currentText + ") \(string)" : String(currentText.dropLast(2))
return false
}else if(newCount == 10){
textField.text = addingCharacter ? currentText + "-\(string)" : String(currentText.dropLast(2))
return false
