    Since this is the initial view controller, and is not a subclass, you need to set this in your appDelegate.

    In AppDelegate.m, add the following to your application:didFinishLaunchingWithOptions: method:

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
        // Override point for customization after application launch.
    
        // Select the left-most tab of our initial tab bar controller:
        UITabBarController *tabBar = (UITabBarController *)self.window.rootViewController;
        tabBar.selectedIndex = 0;
        return YES;
    }
