标签栏未显示

Question

从通知中打开我的应用时，我有一个特定的视图。导航栏显示，导航正常。我遇到的问题是显示标签栏。这是我的didFinishLaunchingWithOptions方法。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // This prevents the UA Library from registering with UIApplcation by default when
    // registerForRemoteNotifications is called. This will allow you to prompt your
    // users at a later time. This gives your app the opportunity to explain the benefits
    // of push or allows users to turn it on explicitly in a settings screen.
    // If you just want everyone to immediately be prompted for push, you can
    // leave this line out.
    // [UAPush setDefaultPushEnabledValue:NO];

    //Create Airship options dictionary and add the required UIApplication launchOptions
    NSMutableDictionary *takeOffOptions = [NSMutableDictionary dictionary];
    [takeOffOptions setValue:launchOptions forKey:UAirshipTakeOffOptionsLaunchOptionsKey];

    // Call takeOff (which creates the UAirship singleton), passing in the launch options so the
    // library can properly record when the app is launched from a push notification. This call is
    // required.
    //
    // Populate AirshipConfig.plist with your app's info from https://go.urbanairship.com
    [UAirship takeOff:takeOffOptions];

    // Set the icon badge to zero on startup (optional)
    [[UAPush shared] resetBadge];

    // Register for remote notfications with the UA Library. This call is required.
    [[UAPush shared] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |
                                                         UIRemoteNotificationTypeSound |
                                                         UIRemoteNotificationTypeAlert)];

    // Handle any incoming incoming push notifications.
    // This will invoke `handleBackgroundNotification` on your UAPushNotificationDelegate.
    [[UAPush shared] handleNotification:[launchOptions valueForKey:UIApplicationLaunchOptionsRemoteNotificationKey]
                       applicationState:application.applicationState];

    // self.tabBarController = [[UITabBarController alloc] initWithNibName:@"KFBViewController" bundle:nil];

    // self.tabBarController.customizableViewControllers = nil;

    self.window.rootViewController = self.tabBarController;
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];

    // If application is launched due to  notification,present another view controller.
    UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];

    if (notification)
    {
        ActionAlertsViewController *actionAlerts = [[ActionAlertsViewController alloc] initWithStyle:UITableViewStylePlain];
        WebViewController *wvc = [[WebViewController alloc]init];

        [self.window.rootViewController presentViewController:navController7 animated:NO completion:nil];
    }

    return YES;
