ios - 从应用程序设置中的应用程序注销

Question

我想使用设置包从应用程序中注销。

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

//enable_logout key for logout switch identifire in setting budle plist.
        let userLogout =  UserDefaults.standard.bool(forKey: "enabled_logout")
        print(userLogout)

            let userLogin =  UserDefaults.standard.bool(forKey: "isUserLogin")
            if userLogin {

                let homeController = HomeController()
                let homeNav = UINavigationController.init(rootViewController: homeController)


                let aboutController = AboutController()
                let aboutNav = UINavigationController.init(rootViewController: aboutController)

                let userBaseController = UserBaseInfoController()
                let userBaseNav = UINavigationController.init(rootViewController: userBaseController)

                tabbarController.viewControllers =[homeNav,userBaseNav,aboutNav]

                self.window?.rootViewController = tabbarController

            }
            else {

                let login = LoginController()
                self.window?.rootViewController = login


            }



        return true
    }

我在 appDelegate 中添加了此代码，我想当用户在设置中启用注销开关然后返回到应用程序显示登录视图时，但是当启用开关并返回到应用程序 appDelegate 时不会调用并且我的密钥不会更改。

有我的设置视图：

我正在解决这个问题，而不是检查方法中的enable_logout键didFinishLaunchingWithOptions，我检查了 applicationWillEnterForeground方法。

这是我的代码：

func applicationWillEnterForeground(_ application: UIApplication) {

        let userLogout =  UserDefaults.standard.bool(forKey: "enable_logout")
        print(userLogout)


        if !userLogout {

            let homeController = HomeController()
            let homeNav = UINavigationController.init(rootViewController: homeController)


            let aboutController = AboutController()
            let aboutNav = UINavigationController.init(rootViewController: aboutController)

            let userBaseController = UserBaseInfoController()
            let userBaseNav = UINavigationController.init(rootViewController: userBaseController)

            tabbarController.viewControllers = [homeNav,userBaseNav,aboutNav]

            self.window?.rootViewController = tabbarController

        }
        else {

            let login = LoginController()
            self.window?.rootViewController = login

        }

    }
