UIViewController willRotateToInterfaceOrientation:duration:] 
[UIViewController viewWillLayoutSubviews]
[UIView layoutSubviews] 
[UIViewController viewDidLayoutSubviews]
[UIViewController willAnimateRotationToInterfaceOrientation:duration:]
[UIViewController shouldAutorotateToInterfaceOrientation:]
[UIViewController didRotateFromInterfaceOrientation:]

And when presenting a view controller we get the following:
[UIViewController loadView]
[UIViewController viewDidLoad]
[UIViewController viewWillAppear:]
[UIViewController shouldAutorotateToInterfaceOrientation:]
[UIViewController viewWillLayoutSubviews]
[UIView layoutSubviews]
[UIViewController viewDidLayoutSubviews]
[UIViewController viewDidAppear:]

And finally dismissing a view controller (when orientation was changed in the child view controller):
[UIViewController viewWillAppear:] - Note correct bounds here
[UIViewController viewWillLayoutSubviews]
[UIView layoutSubviews]
[UIViewController viewDidLayoutSubviews]
[UIViewController viewDidAppear:]
