Try like this,

{
    return UIInterfaceOrientationLandscapeLeft;
}

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