cgaffinetransform

In my code I crated two UIView View1 and View2 out of which View2 rotates on finger touch using CGAffineTransform and View1 is drawn like Arrow shaped (triangle) using CGContext. The View1 is steady view (fixed) which Points (shown directed Up) to the Surface of View2 , So I want to detect the View2 surface points when it stopped rotation and appears in front of the view1.

How can I made this possible to detect the UIView Surface when it appears in front of another UIView?
