I have a list of CGPoints that are connected using CGPathAddLineToPoint going from each consecutive point and then the last point is linked to the first point. Thus I have a complete shape. And I want to detect which points belong to the outermost edge of the connected path so that I can remove any loops from the shape. How would I go about doing that?
