Answer 1

enter code hereUse
– willRotateToInterfaceOrientation:duration:
or
– didRotateFromInterfaceOrientation:
instead of viewWillTransitionToSize... .
One will be handed the new orientation and the other will receive the old orientation.
Working with the window's size.height or size.with is not a good idea for this puprpose or at least not by simply using an == operator.
