UINavigationController's navigation bar wont shrink when in Landscape mode

Question

My navigation controller's navigation bar won't change the height when rotated to landscape.

see it stays at 44 pixels instead of 34 i think.

What do i do to fix this?

Answer 1

You have to add your navigation controller directly as a subview to your window, otherwise this doesn't work automatically. (It is not necessary to change the frame of your navigation bar manually.)

The -[application:didFinishLaunchingWithOptions:] method of your AppDelegate should contain something like

[window addSubview:self.yourNavController.view];

To get an example where this works automatically, you can also create a new navigation-based app in XCode and add an implementation for the shouldAutorotateToInterfaceOrientation: method of the RootViewController that always returns YES.

Answer 2

During the autoRotation method of your class, change the frame of your navBar like this:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
    if((self.interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (self.interfaceOrientation == UIInterfaceOrientationLandscapeRight))
    {
         self.navigationController.navigationBar.frame = CGRectMake(0,0,480,32);
    }
    else if((self.interfaceOrientation == UIInterfaceOrientationPortrait) || (self.interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown))
    {
         self.navigationController.navigationBar.frame = CGRectMake(0,0,320,44);
    }
    else
    {
         assert(false);
    }
}
