Alert view does not disappear [iOS]

Question

I have created a custom alert view in which I created custom buttons and removed the default buttons. When I click the custom buttons, the alert view does not disappear. Please help me solve this problem. I am using the following code,

UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:nil message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:nil];
[alertView show];
UILabel *lbladdblock=[[UILabel alloc] initWithFrame:CGRectMake(100,25,100,30)];
[alertView addSubview:lbladdblockname];

UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:nil message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:nil]; [alertView show]; UILabel *lbladdblock=[[UILabel alloc] initWithFrame:CGRectMake(100,25,100,30)]; [alertView addSubview:lbladdblockname]; — Anupama, Feb 13 '14 at 07:23
-(void)gotoWelcomeScreen{ // profileInfoViewController *profile= [self.storyboard instantiateViewControllerWithIdentifier:@"profileInfo"]; scrollingViewController *profile= [self.storyboard instantiateViewControllerWithIdentifier:@"scroller"]; profile.userImagePath=regUserPhoto; profile.phonenum=regPhNumber; profile.selfregistrationId=[NSString stringWithFormat:@"%d",registeredid ]; [self presentModalViewController:profile animated:YES]; } — Anupama, Feb 13 '14 at 07:46

If the cancel button and other button, both are nil, how do you plan to make the alert view disappear? — iphondroid, Feb 13 '14 at 08:15

1.include your .h file : UIAlertViewDelegate

2.please follow below implementation...

UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:nil message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:nil]; 
[alertView show];
UILabel *lbladdblock=[[UILabel alloc] initWithFrame:CGRectMake(100,25,100,30)];
[alertView addSubview:lbladdblockname];    
[self performSelector:@selector(dismiss:) withObject:alert1 afterDelay:1.0];

the dismiss method will be...

-(void)dismiss:(UIAlertView*)alert
{
    [alert dismissWithClickedButtonIndex:0 animated:YES];
}

Or you wants to custom view than use

 UIAlertView*testAlert=[[UIAlertView alloc] initWithFrame:CGRectMake(0, 0, 140, 140)];


UIButton*testButton=[UIButton buttonWithType:UIButtonTypeRoundedRect];
[testButton setFrame:CGRectMake(20, 20, 40, 40)];

[testButton setTitle:@"Hello" forState:UIControlStateNormal];
[testButton addTarget:self action:@selector(someAction) forControlEvents:UIControlEventTouchUpInside];
[testAlert addSubview:testButton];
 [testAlert show];

-(void)someAction

{
[testAlert removeFromSuperView];
}

i am using this code but alert view is dis appear after delay .its not wait until i click the label — Anupama, Feb 13 '14 at 07:42

If your class is subclass of UIAlertView then you can dismiss it by calling this method.

[alert dismissWithClickedButtonIndex:0 animated:TRUE];

you can use self in place of alert if you are using this method inside of class.

To work around this issue, you do like this:

define alertView in header, then:

- (void)viewDidLoad 
{
    alertView = [[UIAlertView alloc] initWithTitle:nil message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:nil];

    UILabel *lbladdblock=[[UILabel alloc] initWithFrame:CGRectMake(0,0,20,30)];
    [lbladdblock setText:@"custom Message"];

    UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [btn setTitle:@"Dismiss!" forState:UIControlStateNormal];
    [btn addTarget:self action:@selector(dismissMe) forControlEvents:UIControlEventTouchUpInside];

    [alertView addSubview:lbladdblock];
    [alertView addSubview:btn];

    [alertView show];
}

 -(void)dismissMe
{
    [alertview dismissWithClickedButtonIndex:0 animated:YES];
}

Also, AFAIK addSubView to alertView is impossible in ios7 so your code will work for previous versions only. See this thread.

Since you are not using built in features of UIAlertView (passing nil in all params)You should prefer some custom alert view. See the sample alert views in link.

Hope it helps!
