无法获取账户信息 Parse & FB SDK

Question

我正在使用 ParseFacebookUtilsV4，而 fb idk 似乎在检索用户信息时遇到问题，只是暂时打印到控制台中。问题是似乎启动请求的块没有被执行，因为每当我调试它似乎只是跳过启动完成处理程序。

// View controller code
        PFFacebookUtils.facebookLoginManager().loginBehavior = .web

        var loginTask = PFFacebookUtils.logInInBackground(withReadPermissions: [])

        loginTask.continue( { (bfTask) -> Any? in

            print("I'm here")

            let request = FBSDKGraphRequest(graphPath:"me", parameters: ["fields":"id,email,name,first_name,last_name,picture"]  )
            print(request)
            request?.start {

                (connection, result, error) in

                print(result)

            }
            return ""
        })

// App delegate config

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

        let configuration = ParseClientConfiguration {
            $0.applicationId = "xxxx"
            $0.clientKey = "xxxxx"
            $0.server = "https://parseapi.back4app.com"
        }
        Parse.initialize(with: configuration)

        PFFacebookUtils.initializeFacebook(applicationLaunchOptions: launchOptions)

        PFTwitterUtils.initialize(withConsumerKey: "xxxxx", consumerSecret: "xxxxx")

        // Override point for customization after application launch.
        return true
    }

这是我用于 Facebook 请求的函数。我正在使用阻止请求：

func loadFacebookUserDetails() {

    // Define fields we would like to read from Facebook User object
    let requestParameters = ["fields": "id, email, first_name, last_name, name"]

    // Send Facebook Graph API Request for /me
    let userDetails = FBSDKGraphRequest(graphPath: "me", parameters: requestParameters)
    userDetails.startWithCompletionHandler({
        (connection, result, error: NSError!) -> Void in
        if error != nil {
            let userMessage = error!.localizedDescription
            let myAlert = UIAlertController(title: "Alert", message: userMessage, preferredStyle: UIAlertControllerStyle.Alert)

            let okAction = UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil)
            myAlert.addAction(okAction)
            self.presentViewController(myAlert, animated: true, completion: nil)

            PFUser.logOut()
            return
        }

        // Extract user fields
        let userId:String = result.objectForKey("id") as! String
        let userEmail:String? = result.objectForKey("email") as? String
        let userFirstName:String?  = result.objectForKey("first_name") as? String
        let userLastName:String? = result.objectForKey("last_name") as? String



        // Get Facebook profile picture
        let userProfile = "https://graph.facebook.com/" + userId + "/picture?type=large"

        let profilePictureUrl = NSURL(string: userProfile)

        let profilePictureData = NSData(contentsOfURL: profilePictureUrl!)


        // Prepare PFUser object
        if(profilePictureData != nil)
        {
            let profileFileObject = PFFile(name:"profilePic.jpeg",data:profilePictureData!)
            PFUser.currentUser()?.setObject(profileFileObject!, forKey: "ProfilePic")
        }

        PFUser.currentUser()?.setObject(userFirstName!, forKey: "Name")
        PFUser.currentUser()?.setObject(userLastName!, forKey: "last_name")



        if let userEmail = userEmail
        {
            PFUser.currentUser()?.email = userEmail
            PFUser.currentUser()?.username = userEmail
        }



        PFUser.currentUser()?.saveInBackgroundWithBlock({ (success, error) -> Void in


            if(error != nil)
            {
                let userMessage = error!.localizedDescription
                let myAlert = UIAlertController(title: "Alert", message: userMessage, preferredStyle: UIAlertControllerStyle.Alert)
                let okAction = UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil)
                myAlert.addAction(okAction)
                self.presentViewController(myAlert, animated: true, completion: nil)
                PFUser.logOut()
                return


            }


            if(success)
            {
                if !userId.isEmpty
                {
                    NSUserDefaults.standardUserDefaults().setObject(userId, forKey: "user_name")
                    NSUserDefaults.standardUserDefaults().synchronize()


                    dispatch_async(dispatch_get_main_queue()) {
                        self.dismissViewControllerAnimated(true, completion: nil)
                    }

                }

            }

        })


    })

}
