Question

in my Alert View, there is two button, OK and Cancel. When the user click the OK button, the delegate method dismissWithClickedButtonIndex:animated get called, and if the index is 0, then i get called to a method to execute some code:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Alert" 
                                                    message:@"Are you sure you want to exit"
                                                   delegate:self cancelButtonTitle: @"OK" 

                                          otherButtonTitles: @"Cancel",nil]; 


    [alert show]; 
    [alert release];//release the reference 

Delegate method:

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex{

    if (buttonIndex==0) {
        [self aMethod];
    }    
}

-(void)aMethod{

//Some useful code
}

Now, what i want to instead of all this, is to execute the code of the aMethod method in the AlertView directly, without referring to A delegate method and a method which get called, something like that:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Alert" 
                                                message:@"Are you sure you want to exit"
                                               delegate:self cancelButtonTitle: @"OK" //Put here some useful code

                                      otherButtonTitles: @"Cancel",nil]; 

Is it possible?

I made a pair of UIAlertView and UIActionSheet subclasses that do exactly that. Grab them here:
https://github.com/rydermackay/RMActionSheet

Use them like this:

RMAlertView *alertView = [RMAlertView alertViewWithTitle:@"Alert!" message:nil];

[alertView addButtonWithTitle:@"OK"
                       action:^{
                           NSLog(@"OK");
                       }];

[alertView addCancelButtonWithTitle:@"Cancel"
                             action:nil];
[alertView show];
