使用带有标签栏控制器的多个故事板

Question

我正在尝试让我的应用程序根据运行的设备加载不同的故事板。现在，我已经能够检测到设备并基于它在 AppDelegate 中设置 rootViewController。但是，我注意到，当我这样做时，我的标签栏控制器消失了。我认为这是因为我只是将 rootViewController 设置为一个新实例。我将如何解决此问题以使标签栏可见？

AppDelegate.swift

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    window =  UIWindow(frame: UIScreen.mainScreen().bounds)
    window?.makeKeyAndVisible()


    if ((UIDevice.currentDevice().modelName == "iPhone 5") || (UIDevice.currentDevice().modelName == "iPhone 5c") || (UIDevice.currentDevice().modelName == "iPhone 5s") || (UIDevice.currentDevice().modelName == "iPhone SE") || (UIDevice.currentDevice().modelName == "iPod Touch 5") || (UIDevice.currentDevice().modelName == "iPod Touch 6")) {

        storyboard = UIStoryboard(name: "iPhoneSE", bundle: nil)
        let rootController = storyboard!.instantiateViewControllerWithIdentifier("login5")

        if let window = self.window {
            window.rootViewController = rootController
        }

        print("-----------------------iPhone5-----------------------")

    } else if ((UIDevice.currentDevice().modelName == "iPhone 6") || (UIDevice.currentDevice().modelName == "iPhone 6s")){

        storyboard = UIStoryboard(name: "iPhone6", bundle: nil)
        let rootController = storyboard!.instantiateViewControllerWithIdentifier("login6")

        if let window = self.window {
            window.rootViewController = rootController
        }

        print("-----------------------iPhone6-----------------------")

    }

只是一个非常愚蠢的想法：您在实例化相关的 StoryBoard 之前使窗口可见。尝试在条件句之后移动 makeKeyAndVisible() 行。
