I want to be able to tell when 2 images collide (not just their frames). But here is the catch: the images are rotating.
So I know how to find whether a pixel in an image is transparent or not but that wont help in this scenario because it will only find the location in the frame relative to a non-rotated image.
Also I have gone as far as trying hit boxes but even those wont work because I can't find a way to detect the collision of UIViews that are contained in different subviews.

Is what I am trying to do even possible? 
Thanks in advance
