UIGestureRecognizer blocks subview for handling touch events

Question

I\'m trying to figure out how this is done the right way. I\'ve tried to depict the situation:

Answer 1

I was displaying a dropdown subview that had its own tableview. As a result, the touch.view would sometimes return classes like UITableViewCell. I had to step through the superclass(es) to ensure it was the subclass I thought it was:

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
    UIView *view = touch.view;
    while (view.class != UIView.class) {
        // Check if superclass is of type dropdown
        if (view.class == dropDown.class) { // dropDown is an ivar; replace with your own
            NSLog(@"Is of type dropdown; returning NO");
            return NO;
        } else {
            view = view.superview;
        }
    }

    return YES;
}
