That line of code is correct. What's the error you're getting?

Are you putting it in the application:didFinishLaunchingWithOptions method before the return?

and this is the whole of the UIColor thing

  • (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. self.window.backgroundColor = [UIColor whiteColor]; [self.window makeKeyAndVisible]; return YES; }

Do you have the following line in your AppDelegate.h file?

@property (strong, nonatomic) UIWindow *window;

Also, make sure you've got your storyboard selected in your Apps target settings.
