Answer 1

you should display it first:

UIAlertView *alert1 = [[UIAlertView alloc]initWithTitle:@"title" message:@"message" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:nil];
    [alert1 show];

then in delegate method

- (void)alertView:(UIAlertView *)alertView willDismissWithButtonIndex:(NSInteger)buttonIndex{
    if(buttonIndex==0){
     // do something
    }
}
