Iphone – Can you force a touch event to cancel after touchesBegan

According to a similar question, your method should work.

This leads me to think that your view's nextResponder is not actually the ViewController, as you suspect.

I would add a quick NSLog in your forwarding code to check what your nextResponder really points to:

if (numTaps < 2) {
    NSLog(@"nextResponder = %@", self.nextResponder);
    [self.nextResponder touchesBegan:touches withEvent:event];
}

You can also change your other NSLog messages so that they output type and address information:

NSLog(@"touched %@", self);

touched <UIView 0x12345678>

This should get you started on diagnosing the problem.

If I understand correctly, the touchesEnded event is detected, but not by the subview that needs to know about it. I think this might work for you:

In a common file, define TOUCHES_ENDED_IN_SUPERVIEW as @"touches ended in superview".

In the touchesEnded method of the containing view that is firing, add

[[NSNotificationCenter defaultCenter] postNotificationName:  TOUCHES_ENDED_IN_SUPERVIEW object: self];

In the touchesBegan of the subviews, add

[[NSNotificationCenter defaultCenter] addObserver: self 
    selector: @selector(touchesEnded:) 
    name: TOUCHES_ENDED_IN_SUPERVIEW 
    object: self.superview]; 

In the touchesEnded methods of the subviews, use your normal logic for the event, and also add

[[NSNotificationCenter defaultCenter] removeObserver: self name: TOUCHES_ENDED_IN_SUPERVIEW object: self.superview];

Remember to put [[NSNotificationCenter defaultCenter] removeObserver: self] in your dealloc as well, in case it is possible to leave the page without getting the touchesEnded event.

You might want the notification to send its message to a special touchesEndedInSuperview method, which would invoke touchesEnded itself, but that depends on whether you have any special processing to do in that case.
