Hide status bar even when warning is displayed

Question

I hide my status bar on a specific viewControllerusing

override func prefersStatusBarHidden() -> Bool {
    return true
}

It works very well until I show a warning on the screen. When a warning appears, a status bar appears, which I do not want. When the warning is disabled, the status bar is hidden again.

Answer 1

Since UIAlertControllerit is now fully functional UIViewController, you must subclass it and add the same method to the new subclass. Then create your subclass instead of simple UIAlertController.

Unconfirmed, but this should do the trick.
