ios - 从应用程序设置中的应用程序注销
<p><p>我想使用设置包从应用程序中注销。 </p>
<pre><code> func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: ?) -> 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 =
self.window?.rootViewController = tabbarController
}
else {
let login = LoginController()
self.window?.rootViewController = login
}
return true
}
</code></pre>
<p>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应用程序显示登录 View 时，但是当启用开关并返回应用程序时 appDelegate 不调用并且我的 key 不改变。</p>
<p>有我的设置 View :

<p><p>我正在解决这个问题，而是检查 <code>didFinishLaunchingWithOptions</code> 方法中的 <code>enable_logout</code> 键，我检查了 <code>applicationWillEnterForeground</code> 方法。</p>
<p>这是我的代码:</p>
<pre><code>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 =
self.window?.rootViewController = tabbarController
}
else {
let login = LoginController()
self.window?.rootViewController = login
}
}
</code></pre></p>
