How do I force a specific UIInterfaceOrientation on an individual view in a UINavigationController?

Question

Okay, so here\'s the situation:

I have an app in which I only want ONE specific view in a UINavigationController to have a landscape orientation. This view is a UIIm

The UINavigationController overrides the contain UIViewController orientation settings, so you have to create a custom subclass of UINavigationController with the following for 5.1:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    if ([[self topViewController] isKindOfClass:[SigCaptureViewController class]]) {
        return UIInterfaceOrientationIsLandscape(interfaceOrientation);
    } else {
        return UIInterfaceOrientationIsPortrait(interfaceOrientation);
    }
}

For 6.0 and above you need:

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations {
    if ([[self topViewController] isKindOfClass:[EXTRASigCaptureViewController class]]) {
        return UIInterfaceOrientationMaskLandscape;
    } else {
        return UIInterfaceOrientationMaskPortrait;
    }
}

What I haven't figured out is how to make the force the UINavigationController to rotate. calling [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:NO] causes the status bar to rotate but doesn't cause the view to rotate.
