Impossible d'ajouter UITextField à UIAlertView sur iOS7 ... fonctionne sous iOS 6

Le code ci-dessous fonctionne sur iOS6 (et les versions antérieures), mais UITextField ne s'affiche pas dans iOS7 ... aucune idée sur la manière d'afficher un UITextField dans un UIAlterView dans iOS7?

UIAlertView* dialog = [[UIAlertView alloc] init];
[dialog setDelegate:self];
[dialog setTitle:@"Enter ESC Score"];
[dialog setMessage:@" "];
[dialog addButtonWithTitle:@"Cancel"];
[dialog addButtonWithTitle:@"OK"];
dialog.tag = 5;

nameField = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)];
[nameField setKeyboardType:UIKeyboardTypeNumberPad];
[nameField becomeFirstResponder];
[nameField setBackgroundColor:[UIColor whiteColor]];
[dialog addSubview:nameField];
CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, 0.0);
[dialog setTransform: moveUp];
[dialog show];
[dialog release];

[nameField release];

Le code exécuté pour iOS6 affiche ceci:

le même code dans iOS7 affiche ceci (remarquez comment UITextField est manquant et qu'il n'y a pas de clavier):

Vous ne pouvez pas facilement modifier la hiérarchie de vues d'un UIAlertView dans iOS 7. (La documentation vous le recommande tout particulièrement.) Rendez-vous sur les forums de développeurs pour consulter un long débat à ce sujet.

Une alternative dans votre cas consiste à définir alert.alertViewStyle = UIAlertViewStylePlainTextInput;. Cela ajoutera un champ de texte pour vous. Vous pouvez y accéder dans le rappel de délégué UIAlertView en utilisant UITextField *textField = [alertView textFieldAtIndex:0];.

@ Aaron Brager avait la bonne solution. En outre, j'ai ajouté une ligne après sa suggestion de définir un clavier numérique par défaut.

UIAlertView* dialog = [[UIAlertView alloc] init];
[dialog setDelegate:self];
[dialog setTitle:@"Enter ESC Score"];
[dialog setMessage:@" "];
[dialog addButtonWithTitle:@"Cancel"];
[dialog addButtonWithTitle:@"OK"];
dialog.tag = 5;

dialog.alertViewStyle = UIAlertViewStylePlainTextInput;
[dialog textFieldAtIndex:0].keyboardType = UIKeyboardTypeNumberPad;

CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, 0.0);
[dialog setTransform: moveUp];
[dialog show];
[dialog release];

UIAlertView *alertView = [[UIAlertView alloc]
                                  initWithTitle:@"Credit Card Number"
                                  message:@"Please enter your credit card number:"
                                  delegate:self
                                  cancelButtonTitle:@"Cancel"
                                  otherButtonTitles:@"Ok", nil];
        [alertView setAlertViewStyle:UIAlertViewStylePlainTextInput];
        /* Display a numerical keypad for this text field */
        UITextField *textField = [alertView textFieldAtIndex:0];
        textField.keyboardType = UIKeyboardTypeNumberPad;

[alertView show];

Je travaille comme un charme

Deux UITextField dans UIAlertView pour toutes les versions d'iOS

-(IBAction) showAlertView {

    UIAlertView *alert;  
    UITextField *callForwardNumber;
    UItextField *callForwardCondition;

    alert = [[UIAlertView alloc] initWithTitle:@"Enter Phone Number & Rule"
                                   message:@""
                                  delegate:self
                         cancelButtonTitle:@"Cancel"
                         otherButtonTitles:@"Save", nil];

    //alert.transform = CGAffineTransformMakeTranslation(0, 110);

    callForwardNumber = [[UITextField alloc] init];
    callForwardNumber.keyboardType = UIKeyboardTypeNumberPad;
    callForwardNumber.text = [R.prefs objectForKey:@"fwd_number"];
    callForwardNumber.borderStyle = UITextBorderStyleRoundedRect;
    callForwardNumber.delegate = self;
    callForwardNumber.tag = 1;

    callForwardCondition = [[UITextField alloc] init];
    callForwardCondition.text = callCondition;
    callForwardCondition.borderStyle = UITextBorderStyleRoundedRect;
    callForwardCondition.delegate = self;
    callForwardCondition.tag = 2;
    [callForwardCondition setKeyboardType:UIKeyboardTypeNumberPad];

if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
    UIView* customAccessory = 
                   [[UIView alloc] initWithFrame:CGRectMake(0, 0, 250, 55)];
    callForwardNumber.frame = CGRectMake(0, 0, 245.0, 25.0);
    callForwardCondition.frame = CGRectMake(0, 30.0, 245.0, 25.0);
    [customAccessory addSubview:callForwardNumber];
    [customAccessory addSubview:callForwardCondition];
    [alert setValue:customAccessory forKey:@"accessoryView"];
    [alert show];
} else {
    alert.message = @"\n\n\n";
    [alert show];
    callForwardNumber.frame = CGRectMake(20.0, 45.0, 245.0, 25.0);
    callForwardCondition.frame = CGRectMake(20.0, 75.0, 245.0, 25.0);
    [alert addSubview:callForwardNumber];
    [alert addSubview:callForwardCondition];
}

Vous pouvez également consulter le contrôle personnalisé sur cocoacontrols.com. Regardez MLAertView (ios 7 comme interface utilisateur) et TSAlertView (ios 6 comme interface utilisateur). Ils peuvent également être transformés en angle de rotation.

1) En méthode - (id) initWithAlertTitle: (NSString *) title checkForPassword: (NSString *) mot de passe
vous devriez ajouter

self.alertViewStyle = UIAlertViewStylePlainTextInput;

échantillon:

(id)initWithAlertTitle:(NSString *)title
        checkForPassword:(NSString *)password{
     if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
     {
    self.alertViewStyle = UIAlertViewStylePlainTextInput;
    }
    self = [super initWithTitle:title
                        message:@"" // password field will go here
                       delegate:self
              cancelButtonTitle:@"Cancel"
              otherButtonTitles:@"Enter", nil];
    if (self) {
        self.password = password;
        self.hashTechnique = HashTechniqueNone; // use no hashing by default
        secondMessage = @"Please Enter New Password";
        thirdMessage = @"Please Re-Enter Password";
        secondMessageNew = @"Please Enter Password";
    }

NSLog(@" _password_ %@",_password);
NSLog(@"_old_password_ %@",[[NSUserDefaults standardUserDefaults] objectForKey:kPassword]);

return self;
}

dans la méthode show add next 

(void)show {

    if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
     {

       UITextField *passwordField = [self textFieldAtIndex:0];
       passwordField.delegate = self;
      self.passwordField = passwordField;
    }
   else
   {
               UITextField *passwordField = [[UITextField alloc] initWithFrame:CGRectMake(14, 45, 256, 25)];
               passwordField.secureTextEntry = YES;
               passwordField.placeholder = @"";
               passwordField.backgroundColor = [UIColor whiteColor];



               // Pad out the left side of the view to properly inset the text
               UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 6, 19)];
                passwordField.leftView = paddingView;
                passwordField.leftViewMode = UITextFieldViewModeAlways;

           //    // Set delegate
           self.passwordField.delegate = self;

           // Set as property

            self.passwordField = passwordField;
           // Add to subview
           [self addSubview:_passwordField];
     }

    // Show alert
   [super show];

}

Je suis également confronté au même problème. Pendant le surf, la réponse a fonctionné pour moi. J'espère que ça marche aussi pour vous.

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Folder Name?" message:@"" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];
alertView.tag = 2;
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
[alertView show];

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex    {
    UITextField * alertTextField = [alertView textFieldAtIndex:0];
    NSLog(@"alerttextfiled - %@",alertTextField.text);
}
