Presentation overlay for iOS

Question

When I demo my touch apps to remote teams the people on the other end dont know where I am touching. To remedy this, I have been working on an event intercepting view/window that can display touches over applications. No matter how may variations on nextResponder I call, I am unable to react to the touch and pass it along to the controllers underneath. Specifically scroll views dont react nor do buttons.

Is there a way to take an event, get its position, then pass it along to what ever component would have been responding to it initially (the controller underneath)?

Update:
I am making some progress with a UIView. The new view is always returning NO to pointInside.This works great for when the touch starts, but it doesnt track moves or releases. Is there a strategy to adding gesture recognizers to the touch in order to track its event lifecycle?

After some more due diligence, I found my oversight. In the layer that was on top and displaying the touches, user interaction needed to be set to false. Once I set that to false, I was able to use that layer for display while catching events on the layers below. The project still isn't done but I am one step closer.

Take care, Joe

You could try creating your own subclass of UIApplication that overrides sendEvent:. Your implementation should call [super sendEvent:event] as well as process the event as needed.

Update your main.m and pass the name of you custom UIApplication class as the 3rd parameter to the call of UIApplicationMain.
