force UIViewController to be in Landscape mode iOS7

Question

I've implemented the proper functions, but they don't get triggered? I've tried several solutions here on StackOverFlow, but none of them work. I've tried adding the view to a UINavigationController, also doesn't work.

FakeIDDetailViewController.h:

@interface FakeIDDetailViewController : UIViewController
@end

FakeIDDetailViewController.m:

@interface FakeIDDetailViewController ()

-(BOOL)shouldAutorotate
{
    return NO;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (UIInterfaceOrientationMaskLandscapeLeft);
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeLeft;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeLeft;
}

- (NSUInteger) application:(UIApplication *)application     supportedInterfaceOrientationsForWindow:(UIWindow *)window {
    return UIInterfaceOrientationLandscapeLeft;
}

Answer 1

If you are pushing a view controller to a stack of other view controllers in a navigation controller, requiring landscape only will not work well. You should display the landscape-constraint view controller modally.

Answer 2

For a navigation controller interface, forcing an orientation is not supported by the framework. See my answer here: https://stackoverflow.com/a/15301322/341994

For a workaround (not very good), see my answer here: https://stackoverflow.com/a/16379515/341994

However, forcing an orientation works fine for a presented view controller.
