iOS Hiding/Showing Status Bar & Nav Bar issue.

[troop231]

All is fine when I hide both my navigationBar and my statusBar, but when I want to show both again, I end up with this 20px white space under the navigationBar, and the navigationBar is also 20px too high under the returned statusBar. See screenshot below after the code:

Code I'm using:

- (void)toggleNavBar:(UITapGestureRecognizer *)gesture 
{
    BOOL barsHidden = self.navigationController.navigationBar.hidden;
    [self.navigationController setNavigationBarHidden:!barsHidden animated:YES];
    
    if (!barsHidden) 
    {
        [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
    }
    
    else if (barsHidden) 
    {
        [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationSlide];
    }
}

I appreciate any help.

Thank you in advance!

Have you tried adjusting the frame of the navigation bar (not saying it's the "correct" solution, but it's probably the one I'd go with...)

I think the issue is your XIB
Did you add an status bar there? (otherwise the XML of the XIB gets confused, and it starts at 0 pixels instead of 20 (on a Window base).

Maybe you should show navBar after showing status bar. If navigation calculates its position at the moment when status bar is hidden things may not work as expected.

Thank you! this is what worked for me

- (void)toggleNavBar:(UITapGestureRecognizer *)gesture 
{
    BOOL barsHidden = self.navigationController.navigationBar.hidden;
    
    if (!barsHidden) 
    {
        [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationFade];
    }
    
    else if (barsHidden) 
    {
        [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade];
    }
    
    [self.navigationController setNavigationBarHidden:!barsHidden animated:YES];
}
