iOS Receiving superview's touches events in it's subview

Question: Is there a way to receive touches from superview directly in it's subview (i.e. touches outside of subview's boundaries)?

I'd like to avoid delegation (formal/informal), NSNotification, proxy or any other intermediary solution to forward touch events from one to another view.

This will do the trick. Override pointInside in the subview. Hopefully direct enough for your requirements.

- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event
{
   point = [self convertPoint:point toCoordinateSpace:self.superview];
    CGRect frame = self.superview.frame;
    if (CGRectContainsPoint(frame, point)) {
        return YES;
    }
    return [super pointInside:point withEvent:event];
}
