Workaround for missing UIBarButtonItem's TouchUp event

using a UIButton allows me to catch TouchUpInside and TouchUpOutside events to know when the user releases the button with his finger.

UIBarButtonItem doesn't have any events/notifications to be used in this manner.

Does anyone know a nice workaround to know when a UIBarButtonItem is physically released? Is there a way to use an UIButton in a UIToolBar with the sa开发者_StackOverflow中文版me "design" and behavior like a UIBarButtonItem?

Thanks!

    IBOutlet UIBarButtonItem *barButton;
....


- (void)viewDidLoad
{
  barButton.action = @selector(onBarButtonTap);

....

- (IBAction)onBarButtonTap
{
  NSLog( @"BarButton Taped" );
}

If you are using a UIToolbar you can drag a UIButton into the bar. It will get embedded inside a UIBarButtonItem and you can link actions to the embedded UIButton
