iphone - SideMenuController を含む tabviewcontroller の前の loginviewcontroller

Question

問題: 4 つのタブを含む tabViewController があり、最初のタブには sideMenuViewControllerを含む homeViewController があります。今、一度だけログインする tabViewController の前に loginViewController を追加したいと思います。以下の AppDelegate.m クラスのコード。

Now I want to include loginViewController before the tabViewController

AppDelegate.m に必要な変更を提案してください

AppDelegate.m

 (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
tabBarController = (UITabBarController *) self.window.rootViewController;
        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:[NSBundle mainBundle]];


        MFSideMenuContainerViewController *container = (MFSideMenuContainerViewController *)tabBarController.viewControllers [0];
        NSParameterAssert ([container isKindOfClass: [MFSideMenuContainerViewController class]]);
    //    UIViewController *historycontr=(UIViewController *)tabBarController.viewControllers[2];
    //    UIViewController *hist=[storyboard instantiateViewControllerWithIdentifier:@"historyController"];
        UINavigationController *navigationController = [storyboard instantiateViewControllerWithIdentifier:@"navigationController"];
        UIViewController *leftSideMenuViewController = [storyboard instantiateViewControllerWithIdentifier:@"leftSideMenuViewController"];
        UIViewController *rightSideMenuViewController = [storyboard instantiateViewControllerWithIdentifier:@"rightSideMenuViewController"];

        [container setLeftMenuViewController:leftSideMenuViewController];
        [container setRightMenuViewController:rightSideMenuViewController];
        [container setCenterViewController:navigationController];



        return YES;
    }
