iOS - Force Landscape Orientation

问题

I've been trying to figure this out for a while now and its possibly a duplicate but I haven't found a correct solution. So I've created a view controller and the build the xib in landscape mode. When I try to push the view controller, it displays as Portrait but I want it to show up landscape. I've added the following methods to my code:

- (BOOL)shouldAutorotate {
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight || interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}

Any help is appreciated!
