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;
         


        

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
}

Answer 2

This works for me :

-(bool) prefersHomeIndicatorAutoHidden {

return NO;

}

Answer 3

Adding the following to the ViewController did the trick for me:

- (UIRectEdge)preferredScreenEdgesDeferringSystemGestures
{
    return UIRectEdgeBottom;
}

This made the Home Indicator more transparent and inactivated so that it requires an extra swipe in order to leave the game.

You can also use UIRectEdgeAll instead of UIRectEdgeBottom to defer the system gestures on all edges of the screen.

Answer 4

It is a choice between hidden and deferred but NOT both

-(BOOL)prefersHomeIndicatorAutoHidden
{
    // YES for hidden (but swipe activated)
    // NO for deferred (app gets priority gesture notification)
    return NO;  
}

register the gesture in viewDidLoad

UIScreenEdgePanGestureRecognizer *sePanGesture = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:@selector(handleGesture:)];
sePanGesture.edges = UIRectEdgeAll; 
// or just set the bottom if you prefer, top-right seems to behave well by default
[self.view addGestureRecognizer:sePanGesture]; 

and define the handleGesture, no need to do anything there for this to work

- (void)handleGesture:(UIScreenEdgePanGestureRecognizer *)recognizer {
    // to get location where the first touch occurred from docs
    // CGPoint location = [recognizer locationInView:[recognizer.view superview]]; 

    NSLog(@"gestured");
}

should be it
