使用BlackBerry Dynamics SDK时如何访问rootViewController

Question

我正在部署具有多个视图控制器的ios 13应用程序（使用情节提要，没有导航控制器，没有启动屏幕）。为了关闭/显示视图控制器，我使用以下代码：

@objc func onMenuItemUploadsTap(_ sender: UIView) {
    self.view.window!.rootViewController?.dismiss(animated: false, completion: {
        let appDelegate = UIApplication.shared.delegate as! AppDelegate
        let vc = appDelegate.getViewController(viewController: .Uploads)
        vc.modalPresentationStyle = .fullScreen
        UIApplication.shared.windows.first!.rootViewController!.present(vc, animated: true, completion: nil)
    })
}

实例化viewController后，我将它们保留在AppDelegate中，因为用户可以从viewController跳转到viewController因此，viewController必须保持其状态/值，这就是为什么要使用：

let vc = appDelegate.getViewController(viewController: .Uploads)

好吧……当我在发布模式下运行该应用程序时，仅显示初始viewController（名为：HomeController），而不显示我想展示的'vc'，调试控制台让我知道：]]

Attempt to present <XXX.UploadController: 0x7ffc71152400> on <UIViewController: 0x7ffc70714c40> whose view is not in the window hierarchy!

注意：UIViewController：0x7ffc70714c40不是HomeController！（“ HomeController”在情节提要中标记为：是初始视图控制器）

在调试模式下（没有BlackBerry SDK），该应用程序运行正常。

我的AppDelegate :: didFinishLaunchingWithOptions ...：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
       
    // Override point for customization after application launch.
    
#if !DEBUG
    XXXGDiOSDelegate.sharedInstance.appDelegate = self
    GDiOS.sharedInstance().authorize(XXXGDiOSDelegate.sharedInstance)
#else
    let controller = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "HomeController") as? HomeController
    window = UIWindow()
    window?.makeKeyAndVisible()
    window?.rootViewController = controller
#endif
    return true
}
我的问题：使用BlackBerry SDK时如何访问rootViewController？

我正在使用：macOS Mojave 10.14.6，xCode 11.1（11A1027），BlackBerry_Dynamics_SDK_for_iOS_v6.1.0.170

提前感谢！

我尝试过：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
       
    // Override point for customization after application launch.
    let controller = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "HomeController") as? HomeController
    window = UIWindow()
    window?.makeKeyAndVisible()
    window?.rootViewController = controller

#if !DEBUG
    XXXGDiOSDelegate.sharedInstance.appDelegate = self
    GDiOS.sharedInstance().authorize(XXXGDiOSDelegate.sharedInstance)
#endif
    return true
}
和

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
       
    // Override point for customization after application launch.
    
#if !DEBUG
    XXXGDiOSDelegate.sharedInstance.appDelegate = self
    GDiOS.sharedInstance().authorize(XXXGDiOSDelegate.sharedInstance)
#endif

    let controller = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "HomeController") as? HomeController
    window = UIWindow()
    window?.makeKeyAndVisible()
    window?.rootViewController = controller

    return true
}
