How to prevent view resizing/transform when UINavigationBar hides/shows

Question

I have an application with a tab bar and a navigation bar. I push a view controller that is used to show photos, one at a time. It initially shows the bars and forward/back controls; after a delay, these hide, using setNavigationBarHidden:animated: and a custom transform (CGAffineTransformMakeTranslation) on the tab bar. This works, but the view controllers view , which shows the photo, leaps up and down. The same is true if I leave the tab bar out of the equation.

How can I prevent the UINavigationBar from moving my view around? I would like the photo to stay fixed in the screen, with the nav bar dropping down over the top segment of it.

Answer 1

Had this issue and fixed it with a class that inherited from UINavigationController

-(void)viewWillAppear:(BOOL)animated
{
    self.navigationBar.translucent = YES;
}

Worked great for me, didn't had to set style to UIBarStyleBlackTranslucent. So it did kept my colors.

Answer 2

[[navigationController navigationBar] setBarStyle:UIBarStyleBlackTranslucent];
[[navigationController navigationBar] setAutoresizesSubviews:NO];

this seemed to do the trick for me!
