Question

我需要检查用户是否已登录，并相应地重定向它们。将此代码添加到我的应用代理后，我的应用程序将永久停留在纵向模式下，并且不会以横向渲染。我做错了什么？我听说过没有正确设置根视图，或添加子视图或容器等等问题。下面有什么东西看起来不正确可能导致我像我一样被卡住了吗？

谢谢！

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {

    //Redirect user to either home screen, or login/register screen
    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
    var storyboard = UIStoryboard(name: "Main", bundle: nil)
    var initialViewController = storyboard.instantiateViewControllerWithIdentifier("vcLoginGateway") as UIViewController

    var userSettings = UserSettings()

    //Change gateway view controller to the home view controller if logged in
    if (userSettings.IsUserLoggedIn()) {
        initialViewController = storyboard.instantiateViewControllerWithIdentifier("vcHome") as UIViewController
    }

    self.window?.rootViewController = initialViewController
    self.window?.makeKeyAndVisible()

    return true
}

Answer 1

所以我最终使我的登录网关成为初始视图控制器，然后在app委托中检查：

    if (userSettings.IsUserLoggedIn()) {
        var initialViewController = storyboard.instantiateViewControllerWithIdentifier("vcHome") as UITabBarController
        self.window!.rootViewController = initialViewController
    }

现在它仅检查您是否已登录，如果是，则相应地重定向您。这工作，现在我可以旋转我的设备！真棒。谢谢大家

您是否检查过“设备方向”是否已选中“左侧风景”和“右侧风景”？检查构建目标 - ＆gt;常规 - ＆gt;部署信息 - ＆gt;设备方向

Answer 3

请检查一下：

var initialViewController = storyboard.instantiateViewControllerWithIdentifier("vcLoginGateway") as UIViewController

var userSettings = UserSettings()

//Change gateway view controller to the home view controller if logged in
if (userSettings.IsUserLoggedIn()) {
    initialViewController = storyboard.instantiateViewControllerWithIdentifier("vcHome") as UIViewController
}

你把它们都作为UIViewController但是你应该这样做，假设你的ViewCOntroller的名字是NameOfYouViewController，所以你应该写：

initialViewController = storyboard.instantiateViewControllerWithIdentifier("vcHome") as NameOfYouViewController

希望这会有所帮助.. :)
