Answer 1

I think if you think it from the point of CALayer, everything is more clear.

Frame is not really a distinct property of the view or layer at all, it is a virtual property, computed from the bounds, position(UIView's center), and transform.

So basically how the layer/view layouts is really decided by these three property(and anchorPoint), and either of these three property won't change any other property, like changing transform doesn't change bounds.
