How do I add observer to UIButton?

I want be signaled when user will touch button (UIControlEventTouchUpInside). How do I add observer to UIButton?

Solution

  • Look at the documentation of UIControl.

    [myButton addTarget:self 
             action:@selector(touch:) 
   forControlEvents:UIControlEventTouchUpInside];

    This method works for anything that inherits from UIControl (including but not limited to UIButtons :)
