UITextField pour le numéro de téléphone

voici ma solution.. fonctionne très bien! Formate le numéro de téléphone en temps réel. Note: Ceci est pour les numéros de téléphone à 10 chiffres. Et actuellement il le formate automatiquement comme (xxx) xxx-xxxx.. modifier à votre cœur joie.

tout d'abord dans votre shouldChangeCharactersInRange vous voulez rassembler la chaîne entière pour le champ de texte du téléphone et la passer 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. Le regex pourrait probablement être nettoyé un peu. Mais j'ai testé ce code pour un moment et semble passer toutes les cloches. Avis nous également utiliser cette fonction pour supprimer un numéro le numéro de téléphone. Ça marche un peu mieux ici parce qu'on a déjà enlevé tous les autres non-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:@"() "
                                                              options:NSRegularExpressionSearch
                                                                range:NSMakeRange(0, [simpleNumber length])];

else   // else do this one..
    simpleNumber = [simpleNumber stringByReplacingOccurrencesOfString:@"(\d{3})(\d{3})(\d+)"
                                                           withString:@"() -"
                                                              options:NSRegularExpressionSearch
                                                                range:NSMakeRange(0, [simpleNumber length])];
return simpleNumber;

    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

voici ce que j'en pense. Ce qui est proche de ce que fait Apple dans L'application Phone and Contacts (au moins quand votre région est définie aux États-Unis, Je ne suis pas sûr si le comportement change par région).

j'étais particulièrement intéressé à formater jusqu'à 1 (123) 123-1234 et à supporter des numéros plus longs sans formatage. Il y a aussi un bug dans la simple vérification de range.length == 1 (pour supprimer/backspace) dans les autres solutions qui empêche un utilisateur de sélectionner la chaîne entière ou une partie de il et en appuyant sur la touche delete / backspace, cela corrige cette situation.

il y a des comportements étranges qui se produisent lorsque vous commencez à sélectionner une plage au milieu et à éditer, où le curseur finit 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 un UITextField , je présume Qu'Apple utilise en fait un UITextView dans les applications de Contacts et de téléphone car ils maintiennent la position du curseur tout en faisant cela en ligne formatage, ils semblent gérer toutes les petites nuances! J'aimerais qu'ils me donnent de cette sortie de la boîte.

cette solution fonctionne très bien pour les numéros Nord-Américains sans le préfixe de numérotation international (+1) et sans extension. Le numéro sera formaté comme suit: "(212) 555-1234". Il pré-Tapera le") "et le" -", mais supprimera également correctement.

Voici mon code Swift 2 d'un point de vue britannique.

il formatera:

+11234567890 as +1 (123) 456 7890

+33123456789 as +33 1 23 45 67 89

+441234123456 as + 44 1234 123456 (ce qui a été localisé comme 01234 123456) parce que je n'ai pas besoin de voir le code du pays pour les numéros Britanniques.

appelez comme suit:

initInternationalPhoneFormats() //this just needs to be done once

var formattedNo = formatInternationalPhoneNo("+11234567890")

vous pouvez appeler cette méthode chaque fois que vous avez besoin de 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: "#")

malheureusement, vous devez le faire vous-même. L'application contact utilise des API non documentées. Pour une raison quelconque, attacher les formateursd'entrée aux champs de texte n'est pas exposé sur l'iPhone comme il est sur le Mac. N'hésitez pas à déposer un rapport de bogue d'amélioration de fonctionnalité.

J'espère, 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 suggèrent (merci beaucoup!). Pour aider les nouveaux le code plus ce que je vais énumérer pourrait vous aider. 1. vous devez ajouter L'UITextFieldDelegate sur le fichier d'en-tête. 2. Le champ UITextField devrait lier le délégué avec la vue, dans mon cas le Controller UIViewController, qui est le fichier d'en-tête. 3. le champ Uitext devrait être mis en place, ça veut dire, votretextfile.delegate = self, sur l' ".m" fichier.

https://github.com/chebur/CHRTextFieldFormatter fonctionne pour moi comme un charme.

copier / coller à partir de 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 swift:

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
}

voici ma solution pour le format de téléphone 05xx xxx xxxx. Au début j'ai 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 qu'il aide quelqu'un pour différents 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
}

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 champ text à ce controller TextInput et il formatera 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 de caractères complète

vous devez le faire manuellement . prenez une notification de textField et vérifiez la longueur du texte du champ et formatez-le selon le pays. si un problème faites le moi savoir. Je l'ai fait

j'ai une solution pour cela mais elle a un inconvénient, voir si vous pouvez la modifier et l'utiliser. En utilisant ceci, vous pouvez à la fois restreindre le numéro de téléphone à 10 chiffres et le formater selon le format US.

j'utilise ce format X (XXX) XXX XX XX c'est un travail en Turquie,

Je l'utilise avec TableView avec 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
    }
}

et vous pouvez appeler cette func dans

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

}

dans tout indexPath que votre champ de texte dans elle

par exemple mon champ Text dans indexPath numéro 1 donc le code sera

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)

    }
}
