I think this is a good starting point if you want to use Objective C:

When you manage to get this to build and run, look for an opencv face detection example and incorporate that into your iOS app.

If you really want to do this in one go, you can try the link suggested by @Anthony above (https://github.com/ekurutepe/iOS-OpenCV-FaceRec).
