Receiving touch events on more then one UIView simultaneously

Question

I have a bunch of UIViews stacked one upon the other(not nested). I want them all to react to touch, but it seems that the topmost view obscures the views benea

Answer 1

Touches are sent to a single view. That view can then optionally pass them up the responder chain. If you want to handle touches to a collection of views you should have them forward those events up to the next responder and have a common parent of all of them (or their view controller since the controller is also part of the responder chain) handle those touches.
