ios – 当app不在后台时打开通用链接

我有类似的问题 iOS: apple universal link if app is not open?.当我点击通用链接时,应用程序无法进入func应用程序(_应用程序：UIApplication,继续userActivity：NSUserActivity,restorationHandler：@escaping([Any]？) – > Void) – > Bool {}如果它不在后台.

我在didFinishLaunchingWithOptions中添加了一些代码.但它不起作用.非常感谢你如果有人可以提供帮助.

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

    let activityDic = launchOptions?[UIApplicationLaunchOptionsKey.userActivityDictionary]
    if activityDic != nil {
        // ConTinue activity here
        self.window?.rootViewController?.restoreUserActivityState(activityDic as! NSUserActivity)
    }


   return true
}

func application(_ application: UIApplication,conTinue userActivity: NSUserActivity,restorationHandler: @escaping ([Any]?) -> Void) -> Bool {
    if userActivity.activityType == NSUserActivityTypeBrowsingWeb {          
            if let controller = UIStoryboard(name: "Main",bundle: nil).instantiateViewController(withIdentifier: "xxx") as? XXXTableViewController {
                if let window = self.window,let rootViewController = window.rootViewController {
                    var currentController = rootViewController
                    while let presentedController = currentController.presentedViewController {
                        currentController = presentedController
                    }
                    currentController.present(controller,animated: true,completion: nil)
                }
            }
    }

    return true

}

if let url = launchOptions?[UIApplicationLaunchOptionsKey.url] as? URL { //Deeplink
        // process url here
    }
    else if let activityDictionary = launchOptions?[UIApplicationLaunchOptionsKey.userActivityDictionary] as? [AnyHashable: Any] { //Universal link
        for key in activityDictionary.keys {
            if let userActivity = activityDictionarY[key] as? NSUserActivity {
                if let url = userActivity.webpageURL {
                    // process url here
                }
            }
        }
    }
