in some previous posts I was looking for information about CALayer
rotation and now I can rotate layer using core animation.
This mail it's about a strange behaviour, in my simple test I have a
single View and a little image loaded as content of main layer.
in the bottom of View there is a button and when I press this button
rotation starts. The strange behaviour is that also the button rotate
but I set bounds and position of CALafer to be in the middle of the
view and half size of it.
When you configure a view to be layer backed (setWantsLayer:YES) all
subviews of that view become layer backed as well. Any transforms (in
this case rotation) that you apply to that layer also affect all
sublayers (which the layer for your button is).
If you don't want the button to rotation, then you need to place it
outside of the view/layer that is being rotated.
