Forcing Landscape orientation for TabBarController and NavigationController

Question

Hello,
I'm writing an application that need to force LandscapeRight with a UITabBarController that contains a UINavigationController that contains UIViewController.
I can force UIViewController to landscape, but when I add the UINavigationController, the emulator starts as Landscape, but returns to Portrait when I call [window addSubView:], and the viewOrientation field from window switch from 0 to Portrait.
Is there anybody has worked with landscape orientation ? (it's really hard to make a landscape app, indeed).

The code below almost works. It does force landscape orientation. The problem I am having is that the navigation items in the navigation bar are not centering themselves until the device is physically rotated. Hope it helps.

[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
// get height of status bar before setting the status bar to landscape orientation
CGRect statusBarFrame = [[UIApplication sharedApplication] statusBarFrame];
// set the status bar to landscape orientation
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:NO];
// rotate
UIScreen *screen = [UIScreen mainScreen];
CGRect newBounds = CGRectMake(0, 0, screen.bounds.size.height, screen.bounds.size.width - statusBarFrame.size.height);
self.navigationController.view.bounds = newBounds;
self.navigationController.view.center = CGPointMake(newBounds.size.height / 2.0, newBounds.size.width / 2.0);
self.navigationController.view.transform = CGAffineTransformConcat(self.navigationController.view.transform, CGAffineTransformMakeRotation(degreesToRadian(90)));
self.navigationController.view.center = window.center;
here is the function definition
#define degreesToRadian(x) (M_PI * x / 180.0)
