我在Xcode8发布之前开始研究应用程序然后切换,当我尝试使用Facebook登录登录应用程序时出现以下错误

应用程序的实现:openURL:sourceApplication:annotation:not found.请将处理程序添加到App Delegate中.类:GhostGab.AppDelegate

我检查了所有的设置,他们似乎很好.任何帮助将不胜感激

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

    return true
}

  func application(application: UIApplication, openURL url: URL, sourceApplication: String?, annotation: AnyObject) -> Bool {

        application,
        open: url,
        sourceApplication: sourceApplication,
        annotation: annotation)
    // Add any custom logic here.
    return facebookDidHandle
}

        tableView.estimatedRowHeight = 300
        tableView.rowHeight = UITableViewAutomaticDimension
        tableView.scrollEnabled = true

        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        // Return the number of rows in the section.
        return 4
    }
    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) …
