  • This was inspired by this SO answer.

    We intercept a transition from portrait to landscape, and hide the navbar and tab bar, for phones. This gives the entire screen to the display. If the transition is going the other way, this ensures that the tab and nav bars are shown. This will only happen, when starting from portrait, and going into landscape. Otherwise, the bars are always shown.

    Declaration

    Swift

    override func willTransition(to inNewCollection: UITraitCollection, with inCoordinator: UIViewControllerTransitionCoordinator)

    to

    The trait collection at the end of the transition.
    with
