当应用程序通过链接点击打开时，IOS 13 无法处理通用链接点击

Question

我正在尝试通过通用链接点击处理打开的应用程序。在 ios 13 以下，它运行良好，但对于 ios 13，它只能在后台运行应用程序。如果应用程序不在前台或后台工作，单击链接将打开未调用的应用程序继续 userActivity功能。我还尝试在场景委托 willconnnect 中获取它以进行委托。但仍然没有调用我的代码下面有什么问题？

场景代表

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
  guard let _ = (scene as? UIWindowScene) else { return }

  if connectionOptions.userActivities.first != nil {
    self.scene(scene, continue: userActivity!)
   }
}
    func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
    continueUserActivity(userActivity: userActivity)
}
func continueUserActivity(userActivity : NSUserActivity){
    if userActivity.activityType == NSUserActivityTypeBrowsingWeb {
        let url = userActivity.webpageURL!
        let dataDict:[String: String] = [AppLinkManager.appLinkExtraKey: url.absoluteString]

        NotificationCenter.default.post(name: .didReceiveAppLink, object: nil, userInfo: dataDict)
    }
}

应用程序委托

  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
   if let userActivityDict = launchOptions?[.userActivityDictionary] as? [AnyHashable : Any],
      let userActivity = userActivityDict["UIApplicationLaunchOptionsUserActivityKey"] as? NSUserActivity {
       continueUserActivity(userActivity: userActivity)
   }
    return true
  } 
  func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool  {
      continueUserActivity(userActivity: userActivity)
      return true
   }


func continueUserActivity(userActivity : NSUserActivity){
    if userActivity.activityType == NSUserActivityTypeBrowsingWeb {
        let url = userActivity.webpageURL!
        let dataDict:[String: String] = [AppLinkManager.appLinkExtraKey: url.absoluteString]

        NotificationCenter.default.post(name: .didReceiveAppLink, object: nil, userInfo: dataDict)
    }  
  }

您是否尝试过continue userActivity在以下位置实现功能SceneDelegate：

func scene(_ scene: UIScene, continue userActivity: NSUserActivity) { }

我在使用 Firebase DynamicLink 时遇到了同样的问题，看起来 UniversalLinks（可能还有其他几个 API）在SceneDelegate.

因此，如果您的目标是 iOS 13 及更低版本，请尝试同时实现SceneDelegate和AppDelegate
