I have a custom alterviewcontroller which subclasses UIViewController. It works great in apps that are portrait, but in landscape, it's running into issues with the frame orientation. I've tried a bunch of fixes, but none seem to be getting it right.
In the current version, it displays correctly but the main view is the wrong size, so the buttons that are outside of that view are not clickable.
In this image, the Next Turn button is not Clickable, the Go to Black button is. This is landscape left.
