Then, you are explaining your problems incorrectly. You're looking to handle the motion of the face, recognized by the face recognition algorithm and captured by the camera. You can't find that answer in the iOS SDK.
You need to implement your own algorithm to detect those movements and convert it somehow to a group of points or rects in the screen, with their paths of movement. Once you obtained this path, then you can do something with it. But, my word of advice: People don't read PDFs with the gestures of their face or head. It's just silly.
