J'ai un champ de texte où l'utilisateur entre des données. C'est un champ de numéro de téléphone. Si l'utilisateur entre 1234567890
, Je veux qu'il s'affiche comme (123)-(456)-7890
comme type d'utilisateur. Comment est-ce possible?

Cela semblait plus clair et gère la suppression de tous les caractères indésirables de manière beaucoup plus agréable. Formats corrects pour 1 (###) ### - #### ou (###) ### - ####

Nous avons écrit une sous-classe NSFormatter personnalisée pour les numéros de téléphone ici: https://github.com/edgecase/PhoneNumberFormatter
Vous pouvez l'utiliser comme n'importe quelle autre sous-classe NSFormatter.
Merci beaucoup pour la première réponse mais je pense que cette méthode -(int)getLength:(NSString*)mobileNumber
est inutile. Vous pouvez essayer quelque chose comme ci-dessous:
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{
int length = [[self formatNumber:[textField text]] length];
if (length == 10) {
if(range.length == 0) {
return NO;
}
}
if (length == 3) {
NSString *num = [self formatNumber:[textField text]];
textField.text = [NSString stringWithFormat:@"(%@) ",num];
if (range.length > 0) {
[textField setText:[NSString stringWithFormat:@"%@",[num substringToIndex:3]]];
}
}
else if (length == 6) {
NSString *num = [self formatNumber:[textField text]];
[textField setText:[NSString stringWithFormat:@"(%@) %@-",[num substringToIndex:3],[num substringFromIndex:3]]];
if (range.length > 0) {
[textField setText:[NSString stringWithFormat:@"(%@) %@",[num substringToIndex:3],[num substringFromIndex:3]]];
}
}
return YES;
}
- (NSString*)formatNumber:(NSString*)mobileNumber {
mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"(" withString:@""];
mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@")" withString:@""];
mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@" " withString:@""];
mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"-" withString:@""];
mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"+" withString:@""];
int length = [mobileNumber length];
if (length > 10) {
mobileNumber = [mobileNumber substringFromIndex: length-10];
}
return mobileNumber;
}
Pour ceux d'entre vous qui ont besoin d'un formatage international des numéros: https://code.google.com/p/libphonenumber/
Livré avec C++, Java et implémentations JavaScript. Il devrait être facile d'envelopper les implémentations C++ dans un fichier .mm et d'écrire un petit wrapper Objective-C autour de lui.
Vous pourriez peut-être utiliser cette méthode simple:
+ (NSString*) formatPhoneNumber:(NSString *)phoneNumber codeLength:(int) code segmentLength:(int) segment
{
NSString* result = @"";
int length = [phoneNumber length];
NSString* firstSegment = @"";
NSString* restSegment = @"";
for (int i=0; i<length; i++) {
char c = [phoneNumber characterAtIndex:i];
if(i < code)
firstSegment = [firstSegment stringByAppendingFormat:@"%c", c];
else
{
restSegment = [restSegment stringByAppendingFormat:@"%c", c];
int threshold = (i - code) + 1;
if((threshold % segment == 0) && (threshold > 0) && !(threshold > length))
restSegment = [restSegment stringByAppendingFormat:@"%c", '-'];
}
}
result = [result stringByAppendingFormat:@"%@-%@", firstSegment, restSegment];
return result;
}
En supposant que la méthode ci-dessus est dans la classe Contact
, utilisez simplement la méthode comme ceci:
NSString* phoneNumber = @"085755023455";
NSString* formattedNumber = [Contact formatPhoneNumber:phoneNumber codeLength:3 segmentLength:4];
Ce serait quelque chose comme:
085-7550-2345-5
Une option valide est https://github.com/iziz/libPhoneNumber-iOS Toutes les autres réponses ne couvrent qu'une petite partie des possibilités et des combinaisons, cette bibliothèque analyse et valide réellement CHAQUE numéro de téléphone, et identifier:
