iOS Navigation, TabBarController, subviews in landscape

[estupefactika]

Hi, I want to change the orientation to landscape in all my app. I have a navigationController and a tabBarController. I did this and it works fine, but I have a little problem with the orientation of the UIWindow.

I detail what I did:

I made a Custom Tab Bar Controller class , over-rode shouldAutorotateToInterfaceOrientation for this class.

//In applicationDidFinishLaunching
tabBarController = [[TabbarController alloc] initWithNibName:nil bundle:nil];
	[tabBarController setViewControllers:controllers animated:YES];
	tabBarController.customizableViewControllers = controllers;
	tabBarController.delegate = self;
	 
	tabBarController.moreNavigationController.navigationBar.tintColor=[UIColor blackColor];
        [tabBarController shouldAutorotateToInterfaceOrientation:UIInterfaceOrientationLandscapeRight];
	// Set up the window		
	[window addSubview:tabBarController.view];
	[window makeKeyAndVisible];

In info.plist, I added:
<key>UIInterfaceOrientation</key>
<string>UIInterfaceOrientationLandscapeRight</string>


And it works, my navigation, tabBarcontroller and my subviews are in landscape. But in my viewController I have a subview of UIWindow that i dont get to rotate, its a subview that covers the entire screen and I remove it after:

startView= [[UIView alloc] initWithFrame:CGRectMake(0.0f,0.0f, 480.0f, 320.0f)];
startView.backgroundColor = [UIColor blackColor];
	
	logo =[[UIImageView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 298.0f, 26.0f)];
	logo.image=[UIImage imageNamed:@"logo.png"];
	logo.contentMode=UIViewContentModeScaleToFill;
	[startView addSubview:logo];
	logo.center=CGPointMake(250,100);
	[logo release];
	
	[window addSubview:startView];

window is in portrait, I tested this:

// Rotates the view.
	CGAffineTransform transform = CGAffineTransformMakeRotation(3.14159/2);
	window.transform = transform;
	
	// Repositions and resizes the view.
	CGRect contentRect = CGRectMake(0, 0, 480, 320);

	window.bounds = contentRect;

If I do this, window is in landscape but rest of my app is broken graphically.

Am I missing something? Any idea? Thanks
