Title Body

I am trying to intercept any activity (i.e. touches) that happens inside my whole application. In other words, I am trying to be notified of any touch event that happens within my main UIView, containing the rest of my controls. To do so, I thought the UIView's method -hitTest:withEvent: was a good solution. However, when I NSLog into this overriden method before calling [super hitTest:... withEvent:...], I see that it is called 3 times for any touch I make, and I cannot see any difference in the event I receive each time it is called. Here is how is implemented the method in the main view of my application : - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event { NSLog(@"hitTest:withEvent called :"); NSLog(@"Event: %@", event); NSLog(@"Point: %@", NSStringFromCGPoint(point)); NSLog(@"Event Type: %d", event.type); NSLog(@"Event SubType: %d", event.subtype); NSLog(@"---"); return [super hitTest:point withEvent:event]; } And here is what I NSLog for a single touch in this view : 2010-11-29 14:09:26.892 Application[68818:207] hitTest:withEvent called : 2010-11-29 14:09:26.892 Application[68818:207] Event: <UITouchesEvent: 0x5716d60> timestamp: 37935.2 touches: {( )} 2010-11-29 14:09:26.892 Application[68818:207] Point: {173, 498} 2010-11-29 14:09:26.892 Application[68818:207] Event Type: 0 2010-11-29 14:09:26.892 Application[68818:207] Event SubType: 0 2010-11-29 14:09:26.893 Application[68818:207] --- 2010-11-29 14:09:26.893 Application[68818:207] hitTest:withEvent called : 2010-11-29 14:09:26.893 Application[68818:207] Event: <UITouchesEvent: 0x5716d60> timestamp: 37935.2 touches: {( )} 2010-11-29 14:09:26.893 Application[68818:207] Point: {173, 498} 2010-11-29 14:09:26.893 Application[68818:207] Event Type: 0 2010-11-29 14:09:26.893 Application[68818:207] Event SubType: 0 2010-11-29 14:09:26.893 Application[68818:207] --- 2010-11-29 14:09:26.
