Besides subclassing your tabBarController as you did overriding houldAutorotateToInterfaceOrientation, you must do the following:

In the viewDidLoad method of the controller in which you want to add a view to be rotated:

self.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

Add this delegate method in the controller in which you want to add a view to be rotated:

 - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
    //NSLog(@"didRotateFromInterfaceOrientation");


    if((fromInterfaceOrientation == UIInterfaceOrientationPortrait) ||
       (fromInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown))
    {    

        YourAppDelegate *mainDelegate = (YourAppDelegate *)[[UIApplication sharedApplication] delegate];
    [mainDelegate.tabBarController.view addSubview: viewToBeRotated];

    [viewToBeRotated setHidden:NO];

    return;

}

if(fromInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || fromInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
{
    [viewToBeRotated removeFromSuperview];
    [self.view setHidden:NO];
}

}

You may also want to add the following method:

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

if (toInterfaceOrientation == UIInterfaceOrientationPortrait)
{
    //self.view = self.portrait;
    YourAppDelegate *mainDelegate = (YourAppDelegate *)[[UIApplication sharedApplication] delegate];
    [viewToBeRotated removeFromSuperview];
    mainDelegate.tabBarController.view.transform = CGAffineTransformIdentity;
    mainDelegate.tabBarController.view.transform = CGAffineTransformMakeRotation(degreesToRadian(0));
    mainDelegate.tabBarController.view.bounds = CGRectMake(0.0, 0.0, 300.0, 480.0);

}
else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft)
{
    YourAppDelegate *mainDelegate = (YourAppDelegate *)[[UIApplication sharedApplication] delegate];
    [mainDelegate.tabBarController.view addSubview: viewToBeRotated];
    mainDelegate.tabBarController.view.transform = CGAffineTransformIdentity;
    mainDelegate.tabBarController.view.transform = CGAffineTransformMakeRotation(degreesToRadian(-90));
    mainDelegate.tabBarController.view.bounds = CGRectMake(0.0, 0.0, 460.0, 320.0);
}
else if (toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
{


//self.view = self.portrait;
        YourAppDelegate *mainDelegate = (YourAppDelegate *)[[UIApplication sharedApplication] delegate];
        [viewToBeRotated removeFromSuperview];
        mainDelegate.tabBarController.view.transform = CGAffineTransformIdentity;
        mainDelegate.tabBarController.view.transform = CGAffineTransformMakeRotation(degreesToRadian(180));
        mainDelegate.tabBarController.view.bounds = CGRectMake(0.0, 0.0, 300.0, 480.0);
    }
    else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
    {
        YourAppDelegate *mainDelegate = (YourAppDelegate *)[[UIApplication sharedApplication] delegate];
        [mainDelegate.tabBarController.view addSubview: viewToBeRotated];
        mainDelegate.tabBarController.view.transform = CGAffineTransformIdentity;
        mainDelegate.tabBarController.view.transform = CGAffineTransformMakeRotation(degreesToRadian(90));
        mainDelegate.tabBarController.view.bounds = CGRectMake(0.0, 0.0, 460.0, 320.0);
    }
}
