title: UIImagePickerController does not forward pinch/zoom events (multi touch) to the CameraOverlayView
body: <p>I have developed an application on the appstore that uses an overlay over the camera (UIImagePickerController) which the user can pan and zoom using touch gestures. The overlay view is a subclass to a UIView and overrides the touches events from UIResponder to modify the overlay view accordingly.</p>
  
  <p>This works fine in iOS3-4 but zoom stopped working for iOS5. It seems as the UIImagePickerController does only forward single touch events and takes over the pinching gestures to enable zoom of the camera.</p>
  
  <p>Do anyone know how to handle this? I would like to disable the zoom of the camera and enable it on my overlay view again.</p>
