Navigationbar is positioned below the hidden statusbar

Question

coming from a TableView, I am creating an MKMapView. I want to have more screen real estate, so I hide the status bar und set the navigation bar to transluscent.

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationFade];

self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
self.navigationController.navigationBar.translucent = NO;

Unfortunaltely the navigation bar is positioned below the hidden status bar (see picture).

I already found out that this might help, since one can perform kind of a reload of the bar in the main event loop:

[self performSelector:@selector(setNavigationController:YES) withObject:nil afterDelay:0.1];

But this doesn't work so far. Any hint?

Thanks in advance.

Answer 1

Okay, I found out what to do:

[self performSelector:@selector(setNavigationController:NO) withObject:nil afterDelay:0.1];
[self performSelector:@selector(setNavigationController:YES) withObject:nil afterDelay:0.1];

This switches the navigation bar off and on again, which forces it to redraw in the correct position.

Answer 2

I use this in iOS 6:

self.navigationController.navigationBarHidden = YES;
self.navigationController.navigationBarHidden = NO;
