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

Question

Le code ci-dessous fonctionne sous iOS6 (et avant) mais le UITextField ne s'affiche pas sous iOS7...une idée sur la manière d'afficher un UITextField dans un UIAlterView sous 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 que UITextField est absent et qu'il n'y a pas de clavier) :

Answer 1

Dans iOS 7, vous ne pouvez pas facilement modifier la hiérarchie des vues d'une UIAlertView (et vous ne devriez pas le faire, la documentation vous l'interdit expressément).

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

Answer 2

@Aaron Brager avait la bonne solution. De plus, j'ai ajouté une ligne après sa suggestion de mettre un pavé 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];

Answer 3

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];

Fonctionne 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];
}

}

1) En méthode - (id)initWithAlertTitle :(NSString *)title checkForPassword :(NSString *)password
vous devez 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 le spectacle de la méthode ajouter le suivant

(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];

}
