UIAlertView Button Action

Question

How can I use two actions for UIButton click?I have a UIAlertView showing with two button.Play again and exit.Now i want to execute two method in the click event of these buttons.

UIAlertView is deprecated. You can now use UIAlertController as explained here.

You can create a UIAlertView like this

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Really reset?" 
                          message:@"Do you really want to reset this game?" 
                          delegate:self 
                          cancelButtonTitle:@"Cancel" 
                          otherButtonTitles:@"reset", nil];

[alert show];

To handle AlertView button click, you have to conform to UIAlertViewDelegate protocol.

@interface YourViewController:UIViewController<UIAlertViewDelegate>{
  .......
  .......
}

Then implement UIAlertViewDelegate protocol methods,

- (void)alertView:(UIAlertView *)alertView 
                   clickedButtonAtIndex:(NSInteger)buttonIndex{
    if (buttonIndex == [alertView cancelButtonIndex]){
      //cancel clicked ...do your action
    }else{
      //reset clicked
    }
}

Be sure to conform to the UIAlertViewDelegate protocol. – Nick Weaver Apr 23 '11 at 10:20
oops yes..do one thing too, in the .h file of your controller confirm to UIAlertViewProtocol, ie if your controller name is SomeController in the .h file when we declare @interface SomeController:UIViewController – Krishnabhadra Apr 23 '11 at 10:21
my .h file starting like this already : how can i use another delegate here?@interface GameTableView : UITableViewController – sohel14_cse_ju Apr 23 '11 at 10:39
thank you so much...finally i made your suggestion working....credit goes to you.....have a coffee by my name...:) – sohel14_cse_ju Apr 23 '11 at 12:11
Is there a constant defined for cancel button? It would be great instead of 0 check. – Gökhan Barış Aker Dec 09 '12 at 16:23

[alertView cancelButtonIndex] – SirRupertIII Feb 21 '13 at 22:43
@RahulHawge No longer dabbles in iOS, so bit slow. Thanks for the pointer. Just updated the answer to mention about deprecation. – Krishnabhadra May 09 '16 at 06:41
