Question

4 files for 2 view controllers, firstviewcontroller and MyOverlayView. MyOverlayView just receives touches and sends notification which should be received by firstviewcontroller. Im getting touch event on the overlayview but not receiving the notification at firstviewcontroller. Any ideas?
