I believe what you are looking for is some kind of way to detect a circular movement. I suggest you look into UIGestureRecognizer. If so then perhaps this can help you, it's a UIGestureRecognizer subclass for this purpose.

I used this in an application where I wanted to add the ability to turn a round switch around, a bit like a volume control on a Hi-Fi system. Check it out.
