How to fire uibarbuttonitem click event programmatically

Question

I have created a UIActionSheet

UIActionSheet * action = [[UIActionSheet alloc]initWithTitle:@""
                                                              delegate:self
                                                     cancelButtonTitle: @"cancel"
                                                destructiveButtonTitle: @"OK"
                                                     otherButtonTitles: nil];
          [action showInView:self.view];
          [action release];

On the event of the cancel button in the UIActionSheet I want to fire the event of a UIBarButtonItem, which is in my view.

My question is how can I fire the button event(without touching the button) in the UIActionSheet delegate method

Answer 1

Another way to do that and avoiding warnings is as follows:

[[UIApplication sharedApplication] sendAction:barButtonItem.action
                                           to:barButtonItem.target
                                         from:nil
                                     forEvent:nil];

Answer 2

Not knowing the current bar button item action you can invoke it this way:

[barButtonItem.target performSelector:barButtonItem.action]

This will however bring "unknown selector" compiler warning, but this may be worked around.
