Passing through touches to UIViews underneath

Question

I have a UIView with 4 buttons on it and another UIView on top of the buttons view. The top most view contains a UIImageView with a <

Answer 1

I have a another solution. I have two views, let's call them CustomSubView that were overlapping and they should both receive the touches. So I have a view controller and a custom UIView class, lets call it ViewControllerView that I set in interface builder, then I added the two views that should receive the touches to that view.

So I intercepted the touches in ViewControllerView by overwriting hitTest:

- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
    return self;
}

Then I overwrote in ViewControllerView:

- (void)touchesBegan:(NSSet *)touches
           withEvent:(UIEvent *)event
{
    [super touchesBegan:touches withEvent:event];
    for (UIView *subview in [self.subviews reverseObjectEnumerator])
    {
        if ([subview isKindOfClass:[CustomSubView class]])
        {
            [subview touchesBegan:touches withEvent:event];
        }
    }
}

Do the exact same with touchesMoved touchesEnded and touchesCancelled.
