iPhone-X - How to force user to swipe twice home indicator to go home-screen

Question

I'm using the code below to hide the home indicator on iPhone X, which is working fine in the emulator.

-(BOOL)prefersHomeIndicatorAutoHidden
{
    return YES;
}

But even though it's hidden, I am still able to swipe up from the bottom and my game goes to the home screen.

I have seen a few games where the user has to swipe up once to bring up the home indicator and swipe up again to go to the home screen.

So, how can I force the user to swipe the home indicator twice to go to the home screen in iOS 11 with Objective-C?

This behavior is required for full-screen games.

Answer 1

I had the same problem.

PrefersHomeIndicatorAutoHidden must return NO but also PreferredScreenEdgesDeferringSystemGestures must be overridden and return UIRectEdgeBottom.

Swift 4.2

override var prefersHomeIndicatorAutoHidden: Bool {
  return false
}

override var preferredScreenEdgesDeferringSystemGestures: UIRectEdge {
  return UIRectEdge.bottom
}
