I'm debugging a project that was working fine in iOS7.1, but does not lay out it's content properly in iOS 8.0. I've narrowed the issue down to this method:

 [self orientRootViewControllerForOrientation:rootViewController.interfaceOrientation];

iOS8 no longer returns correct UIInterfaceOrientation from rootViewController.interfaceOrientation, instead it returns "upside down".

Reading the documentation, I'm confronted with a cryptic message:

Use viewWillTransitionToSize:withTransitionCoordinator: to make interface-based adjustments.

Reading documentation on UIViewControllerTransitionCoordinator, I don't see it having any properties. How can I modify my method that expects an interface orientation to get it's orientation from UIViewControllerTransitionCoordinator?

Basically you are supposed now to layout your content based on the available size, no more on the rotation. Which results in big pains to support older rotation-based code.

The view controller transition coordinator provides a UIViewControllerTransitionCoordinatorContext that has a rotation factor. This could give you the hint you need ? This blog post mentions this too.

You also have the usual device ([UIDevice currentDevice].orientation) or status bar orientation. In case you are working on iOS 6 rotation methods, this post has relevant informations too.
