Firebase Deeplink 不调用 Swift 3 中 AppDelegate 的 application:continueUserActivity:restorationHandler 函数

Question

我正在使用 firebase Deeplink URL 打开我的应用程序的特定部分。当应用程序在后台运行时它运行良好，但是当我杀死应用程序并从外部单击深层链接 url 时我不知道如何处理这种情况，我的意思是我应该在哪里写我的条件来获取 url 的参数。

应用程序在后台时调用此应用程序委托方法

   @available(iOS 8.0, *)
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([Any]?) -> Void) -> Bool {
    guard let dynamicLinks = DynamicLinks.dynamicLinks() else {
        return false
    }
    let handled = dynamicLinks.handleUniversalLink(userActivity.webpageURL!) { (dynamiclink, error) in
        if let dynamicLink = dynamiclink, let _ = dynamicLink.url
        {
            var path = dynamiclink?.url?.path
            path?.remove(at: (path?.startIndex)!)
            let delimiter = "/"
            var fullNameArr = path?.components(separatedBy: delimiter)
            let type: String = fullNameArr![0]
            let Id: String? = (fullNameArr?.count)! > 1 ? fullNameArr?[1] : nil
            if(type == "games")
            {
                self.callGameDetailView(gameId: Id! , gameType: "created", notificationId: "NIL" )

            }else{
                var paths = dynamicLink.url?.path
                paths?.remove(at: (path?.startIndex)!)
                self.setRewardViewController(paths!)

            }
        } else {
            // Check for errors
        }
    }
    return handled
}

但是当我杀死应用程序并点击动态链接网址时，它不会调用 open url 方法：

@available(iOS 9.0, *)
func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any])
    -> Bool {

   return self.application(application, open: url, sourceApplication: nil, annotation: [:])


}


func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {

    let dynamicLink = DynamicLinks.dynamicLinks()?.dynamicLink(fromCustomSchemeURL: url)
    if let dynamicLink = dynamicLink
    {
        var path = dynamicLink.url?.path
        path?.remove(at: (path?.startIndex)!)
        let delimiter = "/"
        var fullNameArr = path?.components(separatedBy: delimiter)
        let type: String = fullNameArr![0]
        let Id: String? = (fullNameArr?.count)! > 1 ? fullNameArr?[1] : nil
        if(type == "games")
        {
            self.callGameDetailView(gameId: Id! , gameType: "created", notificationId: "NIL" )

        }else{
            var paths = dynamicLink.url?.path
            paths?.remove(at: (path?.startIndex)!)
            self.setRewardViewController(paths!)
            return true
        }
    }

    return FBSDKApplicationDelegate.sharedInstance().application(
        application,
        open: url,
        sourceApplication: sourceApplication,
        annotation: annotation)
}

简而言之，我不知道如何在应用程序第一次运行或杀死应用程序后运行时处理动态链接？

我也有同样的问题，你需要从 launchOptions 获取 NSUserActivity

var launchURL :URL? = nil

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
            ....
            // this code should have worked but not working for me with Xcode 9
            //        if let userActivityDictionary = launchOptions?[.userActivityDictionary] as? [UIApplicationLaunchOptionsKey : Any],
            //            let auserActivity = userActivityDictionary[.userActivityType] as? NSUserActivity {
            //            launchURL = auserActivity.webpageURL
            //        }

             if let userActDic = launchOptions?[UIApplicationLaunchOptionsKey.userActivityDictionary] as? [String: Any],
                        let  auserActivity  = userActDic["UIApplicationLaunchOptionsUserActivityKey"] as? NSUserActivity{

                        NSLog("type \(userActDic.self),\(userActDic)") // using NSLog for logging as print did not log to my 'Device and Simulator' logs
                        launchURL = auserActivity.webpageURL
                    }
            ...
            }

func applicationDidBecomeActive(_ application: UIApplication) {
            if let url = self.launchURL {
                self.launchURL = nil

                DispatchQueue.main.asyncAfter(deadline: .now()+2.0, execute: {
                    // wait to initalize notifications

                    if let dynamicLinks = DynamicLinks.dynamicLinks()  {
                        NSLog("handling \(dynamicLinks)")
                        dynamicLinks.handleUniversalLink(url) { (dynamiclink, error) in
                            if let link = dynamiclink?.url {
                                NSLog("proceessing \(dynamicLinks)")
                                let strongMatch = dynamiclink?.matchConfidence == .strong
    // process dynamic link here
                                self.processDynamicLink(withUrl: link, andStrongMatch: strongMatch)
                            }
                        }

                    }

                })
            }

        }
