I'm wondering how to track touches anywhere on the iPhone screen and still have UIButtons respond to taps.

I subclassed a UIView, made it full screen and the highest view in the hierarchy, and overrode its pointInside:withEvent method. If I return YES, I'm able to track touches anywhere on the screen but the buttons don't respond (likely because the view is instructed to handle and terminate the touch). If I return NO, the touch passes through the view and the buttons respond, but I'm not able to track touches.

Do I need to subclass UIButton or is this possible through the responder chain? What am I doing wrong?

- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event{
    return NO;
}   

//only works if pointInside:withEvent: returns YES.
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
        NSLog(@"began");    
        [self.nextResponder touchesBegan:touches withEvent:event];
}

//only works if pointInside:withEvent: returns YES.
-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
        NSLog(@"end");      
        [self.nextResponder touchesEnded:touches withEvent:event];
}
