UITextField kann nicht zu UIAlertView auf iOS7 hinzugefügt werden ... funktioniert in iOS 6

Können Sie nicht einfach ändern, die view-Hierarchie ein uialertview-Objekt in iOS 7. (Noch sollten Sie sein; die Dokumentation, insbesondere sagt Sie nicht.) Den Kopf über die Entwickler-Foren, um zu sehen, eine lange Diskussion darüber.

Einer alternative in Ihrem Fall ist, um alert.alertViewStyle = UIAlertViewStylePlainTextInput; Dies fügt ein Textfeld für Sie. Sie können es in der uialertview-Objekt delegate callback mithilfe UITextField *textField = [alertView textFieldAtIndex:0];.

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];

1) In der Methode
- (id)initWithAlertTitle:(NSString *)title checkForPassword:(NSString *)Kennwort

sollten Sie

self.alertViewStyle = UIAlertViewStylePlainTextInput;

Beispiel:

(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;
}

in der Methode anzeigen
fügen Sie neben

(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];

}

Bin ich auch vor demselben Problem, Während des Surfens im Internet erhielt ich die Antwort, es funktioniert für mich. Ich hoffe, dass es auch für Sie arbeiten.

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);
}
