AppDelegate的应用开始设置错误

Question

我添加了appdelegate didfinishlaunchingwithoptions标签栏菜单。添加此菜单后打开应用程序时，它总是从MainTableView开始。即使我退出了应用程序，当应在MainTableView中打开应用程序时，也会打开LoginViewController页面。换句话说，我希望在用户退出应用程序后打开应用程序时返回登录页面。添加tabbar菜单后，我遇到了这样的问题。

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, MessagingDelegate, UITabBarControllerDelegate {

var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        if #available(iOS 10.0, *) {
            // For iOS 10 display notification (sent via APNS)
            UNUserNotificationCenter.current().delegate = self
            let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
            UNUserNotificationCenter.current().requestAuthorization(
                options: authOptions,
                completionHandler: {_, _ in })
            // For iOS 10 data message (sent via FCM
            Messaging.messaging().delegate = self
        } else {
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        }

        application.registerForRemoteNotifications()
        FirebaseApp.configure()
