xcode iOS6 orientation landscape - xcode

Question

I see a lot of questions about this subject but am unable to find a solution to the problem I am experiencing. I have created an iPad app that should be Landscape only - it works fine when ran on any os prior to iOS6 but on iOS6 the app opens in portrait view. This screenshot shows what I mean (sorry not a great explanation) http://s1342.beta.photobucket.com/user/designedbyria/media/ScreenShot2012-11-02at122113.png.html
I'm guessing the problem is somewhere in the below code, but I can't be sure. I have set the supported Interface Orientations to Landscape Left and Landscape Right only - but this has not worked. I have also taken a look at the questions here with no luck..
I am using xcode and cordova/phonegap

Answer 1

I had the same problem (but not using cordova/phonegap).
You have to set your view controller as a RootViewController in your appDelegate instead of just adding as a subview.
Replace in you appdelegate:
[self.window addSubview:self.viewController.view];
[self.window makeKeyAndVisible];
By
[self.window setRootViewController:self.viewController];
[self.window makeKeyAndVisible];

Answer 2

You can use the delegate
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
Using this delegate and the application will be present in Landscape mode or any desired orientation mode.
Try it.
