What is the relationship between UIView.frame and CALayer.frame? (both before and after CATransform3D)

How CALAyer.frameis connected with it UIView.frame? (in this case specifically a UIImageView.frame).

Given that the values ​​of a are CALAyer.framepotentially different from UIView.frameafter the conversion CAtransform3D, do they no longer have a relationship? (and, subsequently, should I worry more about managing the sizes of mine CALayer, not mine, UIImageViewin my supervisor?).
