I'm trying to handle touch events with touchesBegan in an overlay to a parent UIView but also allow the touch input to pass through to sibling UIViews underneath. I expected there would be some straight-forward way to process a touch event and then say "now send it to the next responder as if this one didn't exist", but all I can find is the nextResponder method which appears to be giving back the parent to my overlay view. That parent is then not really passing it onto the next sibling of that overlay view so I'm stuck uncertain how to do what seems like a simple task that is usually accomplished with a touch callback that gets a True or False return value to tell it whether to keep processing down the widget hierarchy.
Am I missing something obvious?
