How do I forward touch events to a view behind a uicollectionview?

I have a uicollectionviewcontroller which I use to create a small toolbar at the bottom of the screen. I add the view of the uicollectionviewcontroller to another viewcontroller's view. My problem is that it won't forward touch events to a view underneath it. I did move it to the bottom and that worked for a while but now I need to use 2 uicollection views.

How am I supposed to forward touch events to views beneath a uicollectionviewcontroller's view?

In case the question is still relevant, the following can be used to achieve touch forwarding.

  1. Subclass UICollectionView

  2. Overwrite - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event;

    -(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
    [super touchesEnded:touches withEvent:event];
    [self.yourCustomDelegate forwardTouches:touches withEvent:(UIEvent *)event];
}

    That is how UICollectionView can keep its ability to respond to user interaction, and the same time forward received touches.
