Keeping track of CGAffineTransform's action

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? Thanks, Pierre ___ Cocoa

You are right on an efficiency point of view, except I also use other Quartz functions, for special text renderings for example, in view of later 3D treatments, and it's logically saner to remain in one programming context rather than shift between CGRect and Affine.Yet Apple's philosophy on the ma
