Firebase DeepLink 不适用于 iOS14 中已终止/已终止的应用程序状态

Question

我已将其集成Firebase DeepLink/DynamicLinks/UniversalLink到我们的应用程序中。当app is running或 处于, 时background/foreground state，Deep Links工作没有问题。但是，当应用程序处于not running或处于killed/terminated状态时，应用程序将启动，但不会调用或初始化任何触发方法。就像它只触发URL Scheme. 因此，结果，我无法获取所单击的深层链接的数据，这是一个大问题。

IndidFinishLaunchingWithOptions: launchOptions始终为零，因此launchOptions[.url]为零

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

并且open url:options:不触发

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool

当然这个continue userActivity:restorationHandler:不会触发

func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool

因此，我只能启动该应用程序而没有捕获任何数据。任何解决方法或建议表示赞赏。谢谢！

我花了一些时间来解决这个问题。在尝试了一系列解决方法之后，有效的解决方案是迁移到新的Apple's App Structure使用SceneDelegate.

要处理 DeepLink 从终止状态，您需要配置此函数：

var window: UIWindow?

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    if let userActivity = connectionOptions.userActivities.first, let url = userActivity.webpageURL {            
        DynamicLinks.dynamicLinks().handleUniversalLink(url) { dynamicLink, error in
            guard let dynamicLink = dynamicLink, let url = dynamicLink.url else { return }
            parseDynamicLink(fromURL: url)
        }
    }
    
    guard let windowScene = (scene as? UIWindowScene) else { return }
    
    // Initialize UIWindow
    window = UIWindow(windowScene: windowScene)
    window?.rootViewController = YOUR_ROOT_VIEW_CONTROLLER
    window?.makeKeyAndVisible()
}

处理场景委托的其他部分（与 UIApplication 等效）：

func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
    guard let url = userActivity.webpageURL else { return }
    DynamicLinks.dynamicLinks().handleUniversalLink(url) { dynamicLink, error in
        guard let dynamicLink = dynamicLink, let url = dynamicLink.url else { return }
        parseDynamicLink(fromURL: url)
        
        // launch dynamic link code here...?
    }    
}

func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
    guard let urlContext = URLContexts.first else { return }

    if let dynamicLink = DynamicLinks.dynamicLinks().dynamicLink(fromCustomSchemeURL: urlContext.url) {
        guard let url = dynamicLink.url else { return }
        parseDynamicLink(fromURL: url)
    }    
}

如果您计划进行迁移，请确保正确配置您的，Info.plist然后Application Scene Manifest在此处设置场景配置：

func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
    return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}

你的Application Scene Manifest应该看起来像这样：
