Here's Apple's primer on view geometry.

Basically the coordinate system remains with its origin in the top left-hand corner on rotation, so you need to work out where you want your buttons in the new coordinate system.

You also don't seem to have a case in your willAnimateSecondHalfOfRotationFromInterfaceOrinetation method to handle landscape mode.

More fundamentally, "Orientation" is spelt wrong in "willAnimateSecondHalfOfRotationFromInterfaceOrinetation" – are you sure it's actually being called?
