I keep moving an UIImageView with CGAffineTransformTranslate through a timer. That doesn't affect the view's frame and bounds. Is there a variable somewhere that I can read to keep track of the transform or must I create my own?


What do you mean by "keep track of"?

You have the affine transform itself. Why not use the tx and ty members of the CFAffineTransform struct, which represent the translation in x and y?
