xcode iOS6 orientation landscape

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

    // UIDevice isn't firing orientation notifications yet… go look at the status bar
    curDevOrientation = (UIDeviceOrientation)[[UIApplication sharedApplication] statusBarOrientation];
}

if (UIDeviceOrientationIsValidInterfaceOrientation(curDevOrientation)) {
    for (NSNumber *orient in self.viewController.supportedOrientations) {
        if ([orient intValue] == curDevOrientation) {
            forceStartupRotation = YES;
            break;
        }
    }
} 

if (forceStartupRotation) {
    NSLog(@"supportedOrientations: %@", self.viewController.supportedOrientations);
    // The first item in the supportedOrientations array is the start orientation (guaranteed to be at least Portrait)
    UIInterfaceOrientation newOrient = [[self.viewController.supportedOrientations objectAtIndex:0]

intValue]; NSLog(@"AppDelegate forcing status bar to: %d from: %d", newOrient, curDevOrientation); [[UIApplication sharedApplication] setStatusBarOrientation:newOrient];

}


[self.window addSubview:self.viewController.view];
[self.window makeKeyAndVisible];

return YES; }

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];
