iOS Question

How can I make touch events pass through a UIView (similar to pointer-events:none in CSS)?

Could I somehow achieve the same behavior for a

What you're looking for is commonly called "Event Bubbling".

You may refer to the Apple docs here: (Read the Event Delivery: The Responder Chain Section)

So your basic instinct was right, you in fact do need utilize hitTest:withEvent:, but you can further customize things by hooking up into the Responder chain. That section has a very neat example.
