I have a UIViewController with no status bar, and it launches a second UIViewController that has a status bar.

If the extended status bar is active, both views show correctly, but when I exit the second view and go back to the first, I see a 20pt black bar at the top and the whole view is pushed down, obscuring the bottom.

I tried resetting the frame to origin 0,0 in viewDidAppear but it has no effect.

Why is the view pushed down and how can I fix it?

- (BOOL)prefersStatusBarHidden {
   return YES;
}

- (void)viewDidAppear:(BOOL)animated {
   [super viewDidAppear:animated];
   self.view.frame = CGRectMake(0, 0, self.width, self.height);
   self.view.backgroundColor = [UIColor redColor];
}

- (void)openShare {
  Share *share = [[Share alloc] init];
  UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:share];

  nav.modalTransitionStyle = UIModalPresentationPopover;
  [self presentViewController:nav animated:YES completion:nil];
}

top of the view before openShare is called:

top of the view after Share is presented and dismissed:

Yesterday I had the exact same problem in my app.

I made two things that solve the problem.

  1. I set the Top Space to: Top Layout Guide constraint with a constant of 20 (same as status bar height) on my navigationBar
    Constaint

  2. I added this in the controllers that have the issue ([self.view layoutSubviews])

    -(void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    [self.view layoutSubviews];
}
