I think if you set the anchor of your CALayer of the UIIMageView to be the center of the UIImageView youll be ok, right now its set to the upper left corner and so are expiriencing the x and y moving.
Why not just use ball. Center as the position. This way, rotations will have no effect on the position (assuming your image is correctly centered).
If you don't do that the center x,y will not be affected.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
