I am trying to figure out how to drag a UIButton around a circle while maintaining its orientation and also pushing the rest of the buttons along the circle. Basically constrain it to the radius of a circle.

Before drag

If you dragged A around the circle B would stay in front of it and also go around the circle. It is kind of like if you looked at a ferris wheel from the side

after drag thanks in advance

    Is there some programming class or job application that is asking this question? This is the second or third time I have seen this question today. Edit: found them: [Today](http://stackoverflow.com/questions/17953283/ios-implement-a-rotating-wheel-with-custom-views-being-horizontally-stationary) and [yesterday](http://stackoverflow.com/questions/17953283/ios-implement-a-rotating-wheel-with-custom-views-being-horizontally-stationary) – Simon Goldeen Jul 31 '13 at 01:42
