On a UILongPressGestureRecognizer how do I detect which object generated the event?

Question

I have a view with several UIButtons. I have successfully implemented using UILongPressGestureRecognizer with the following as the selector;

- (void)longPress:(

If your view contains multiple subViews (like lots of buttons) you can determine what was tapped:

// Get the position of the point tapped in the window co-ordinate system
CGPoint tapPoint = [gesture locationInView:nil];

UIView *viewAtBottomOfHeirachy = [self.window hitTest:tapPoint withEvent:nil];

if ([viewAtBottomOfHeirachy isKindOfClass:[UIButton class]])
