Question

I have a completely empty single view application targeting iOS 5.1 and I am attempting to get the app to work only in landscape mode.

In the project summary screen I have selected both landscape options and I have deselected portrait options.

I verified in the info.plist that only landscape orientations appear.

In the storyboard I selected the view controller went to simulated metrics and selected landscape for the orientation.

When the app initially opens a black screen is displayed in landscape mode. When the plain white view is displayed it is in portrait mode. I have read through a number of posts and haven’t been able to find a solution to this problem.

I feel like I am overlooking something simple but in the past when I wanted to make an app in landscape mode I just selected landscape in summary and it worked.

Any suggestions would be greatly appreciated.

@interface ViewController ()

@end

@implementation ViewController



- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

Do you have the following function implemented in your root view controller?

    - (NSUInteger)supportedInterfaceOrientations
    {
        return UIInterfaceOrientationMaskLandscapeLeft;
    }
