应用程序在 iOS 中显示黑屏

Question

我正在开发 iOS 应用，其中有带有 TabBar 的侧边菜单，

我已将我的sidemenu container viewController 设置为我的应用程序的 IntitalViewController。

这是我的代码：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
    MFSideMenuContainerViewController *container = (MFSideMenuContainerViewController *)self.window.rootViewController;
    UINavigationController *navigationController = [storyboard instantiateViewControllerWithIdentifier:@"navigationController"];
    UIViewController *leftSideMenuViewController = [storyboard instantiateViewControllerWithIdentifier:@"leftSideMenuViewController"];


    [container setLeftMenuViewController:leftSideMenuViewController];

    [container setCenterViewController:navigationController];


    return YES;
}

这是我的故事板的设计：

当我运行我的应用程序时，我看到一个没有错误的黑屏

哪里出错了，请帮忙

非常感谢！

试试这个（在看到你的代码之后）：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];

    self.window.rootViewController=[[MFSideMenuContainerViewController alloc]init];

    // Override point for customization after application launch.
    MFSideMenuContainerViewController *container = (MFSideMenuContainerViewController *)self.window.rootViewController;

    UITabBarController *tabController = [storyboard instantiateViewControllerWithIdentifier:@"tabBarController"];

    UIViewController *leftSideMenuViewController = [storyboard instantiateViewControllerWithIdentifier:@"leftSideMenuViewController"];



    [container setLeftMenuViewController:leftSideMenuViewController];

    [container setCenterViewController:tabController];


    [self.window makeKeyAndVisible];
    return YES;
}

还提供相应的 id 以在情节提要中查看控制器（用于 tabBar、导航） 并且不要忘记为导航提供根视图控制器 控制器。
