Hide Navigation Bar on rotation

Question

I have a UIView with a navigation bar. How can I hide the navigation bar when the user puts the iPhone in landscape orientation, and have it show again on portrait view?

Answer 1

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
    [[self navigationController] setNavigationBarHidden:UIInterfaceOrientationIsLandscape(toInterfaceOrientation) animated:YES];
    [[UIApplication sharedApplication] setStatusBarHidden:UIInterfaceOrientationIsLandscape(toInterfaceOrientation) animated:YES];
}
