hiding TabBar when rotating iPhone device to landscape

Question

So here is what i have: A UITabBarController that handles different UIViewControllers. In one of the UIViewController i am trying to switch the view being displayed when the

Answer 1

I needed tab bar to go into full screen mode in landscape view and I tried the approach suggested above using

transView.frame = CGRectMake(0, 0, 480, 320 );

This turned out to be a hacky solution and posed many problems such as with hiding and re-displaying the status bar (the view would overlap with the status bar when it is re-displayed after exiting portrait view). I would not recommend this. What worked for me perfectly in the end was pushing a new view controller containing the landscape view and using delegation to reuse the functionality of the original VC.

Answer 2

This approach is working for me:

- (void) willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {

    UIView *parentView = self.tabBarController.view;
    CGRect frame = parentView.frame;
    CGFloat windowHeight = parentView.window.frame.size.height;

    switch (toInterfaceOrientation) {
        case UIInterfaceOrientationLandscapeLeft:
        case UIInterfaceOrientationLandscapeRight:
            CGFloat tabBarHeight = self.tabBarController.tabBar.frame.size.height;
            frame.size.height = windowHeight + tabBarHeight;
            break;
        default:
            frame.size.height = windowHeight;
            break;
    }

    [UIView animateWithDuration:duration animations:^{
        parentView.frame = frame;
    }];
}
