hiding TabBar when rotating iPhone device to landscape

Question

Hi, 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 device rotates to landscape. the important part is that the view displayed in landscape MUST take the whole screen...

I have correctly implemented the methods :

• (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
• (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
• (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation

In fact i do have my rotation occurring correctly, and I my views swaped. i even hide status bar, nav bar and Tab bar BUT i keep having a blank space at the bottom of the screen which is the place of the TabBar...

So i am assuming that setting the hidden property of the tabBar is not enough in order to have the view on the whole screen. I think there is some stuff to do within the TabBarController or even the MainWindow to say somehting like "i don't need TabBarController now". But i do not see how to get around this problem properly.

If anyone has been around this issue, i would appreciate some help.

thank you, Sami.

Answer 1

You can always reset your views frame to fill the gap

Answer 2

This worked for me.

- (void)viewDidLoad {
    [super viewDidLoad];    
    previousRect = self.view.frame; 
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return YES;
}

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration;
{
    if(toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) {  
     [self.navigationController setNavigationBarHidden:TRUE animated:FALSE]; 
     [[UIApplication sharedApplication] setStatusBarHidden:TRUE animated:FALSE];
    }
    else
    {
     [self.navigationController setNavigationBarHidden:FALSE animated:FALSE];
     [[UIApplication sharedApplication] setStatusBarHidden:FALSE animated:FALSE];
    }
}

-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation { 
    UIInterfaceOrientation toOrientation = self.interfaceOrientation;

    if ( self.tabBarController.view.subviews.count >= 2 )
    {
     UIView *transView = [self.tabBarController.view.subviews objectAtIndex:0];
     UIView *tabBar = [self.tabBarController.view.subviews objectAtIndex:1];

     if(toOrientation == UIInterfaceOrientationLandscapeLeft || toOrientation == UIInterfaceOrientationLandscapeRight) {     
      transView.frame = CGRectMake(0, 0, 480, 320 );
      tabBar.hidden = TRUE;
     }
     else
     {    
      transView.frame = previousRect;  
      tabBar.hidden = FALSE;
     }
    }
}
