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 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.

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;
        }
    }
}
