How to set the starting orientation to landscape? - ios6

Question

Hi I was checking the orientations changes of iOS6 and I made everything work fine except one thing. There is no way to start the app on landscape.
How can I do to start the app on landscape? I found this How to force a UIViewController to Portrait orientation in iOS 6 but that's not working, the app ALWAYS start in portrait and I needed to start it on landscape...
When I go to an other view and then go back to the "initial view" it is on landscape! But when the app starts it's on portrait...
Thank you!!
----------------------------- UPDATE -------------------------------
This is how I'm loading from the app delegate the main view:
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
myViewController = [[myViewController alloc] init];
self.navController = [[UINavigationController alloc] initWithRootViewController:myViewController] ;
[self.window setRootViewController:navController];
[self.window makeKeyAndVisible];
----------------------------- UPDATE 2------------------------------
I made it work, I changed the previous code for:
self.navController = [[UINavigationController alloc] init] ;
[self.window setRootViewController:navController];
[self.window makeKeyAndVisible];
[navController presentViewController:myViewController animated:NO completion:NULL];
I hope this is useful for someone else!

Answer 1

Have you tried this?
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:YES];
or
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:YES];
This is working for me in both iOS 6 and iOS 5
I have another problem on trying to rotate the screen than I realize I was making the mistake of try to load the new screen with:
[self.navigationController presentModalViewController:controller animated:YES];
instead of:
[self.navigationController pushViewController:controller animated:YES];
the second one works but the first one wasn't doing what I expected.

This is how I made it work:
self.navController = [[UINavigationController alloc] init] ;
[self.window setRootViewController:navController];
[self.window makeKeyAndVisible];
[navController presentViewController:myViewController animated:NO completion:NULL];
I hope it helps someone else!

I've been wrestling with this too - this is how I've fixed it:
In viewDidLoad:
CGRect frame = self.view.bounds;
if (frame.size.height > frame.size.width) {
//hack to force landscape
CGFloat holdHeight = frame.size.height;
frame.size.height = frame.size.width;
frame.size.width = holdHeight;
self.view.bounds = frame;
}
But I'd prefer a better way.
