ios 9 objective-c screen size issues

Question

I upgrade to ios 9 and xcode 7 (from xcode 6.2) and now this happens when I start my app:

There is now all this black bars above and below.

My appDelegate is like so:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    // Override point for customization after application launch.
    // self.window.backgroundColor = [UIColor whiteColor];
    // [self.window makeKeyAndVisible];



    _startViewController = [[StartViewController alloc] init];
    _startNavigationController = [[StartNavigationController alloc] initWithRootViewController:_startViewController];
    self.window.rootViewController = _startNavigationController;
    [self.window makeKeyAndVisible];

    // Need to fix this since deprecated
    // [application prefersStatusBarHidden:NO];
    // [application preferredS :UIStatusBarStyleDefault];

    // [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

    return YES;
}    

Answer 1

case was missing the LaunchScreen.storyboard in General setting under App icons and launch images:

above function is not work check the follow the below steps:

1. Navigate to project settings
2. Under "App Icons and Launch Images" click on "Use Asset Catalog"
3. Select "Migrate" on the popup that appears.

This should fix the issue.
