【问题描述】：

我有以下几行代码。我应该添加什么以便电子邮件也被存储？ 任何东西都适合 swift

  @IBAction func fblogin(sender: AnyObject) 
    var permissions = ["public_profile","email"]
    PFFacebookUtils.logInWithPermissions(permissions, 
        (user: PFUser!, error: NSError!) -> Void in
        if let user = user 
            if user.isNew 
                println("User signed up and logged in through Facebook!")
                var user = PFUser.currentUser()
                self.performSegueWithIdentifier("login", sender: self)
                //let defaults = NSUserDefaults.standardUserDefaults()

             else 
                println("User logged in through Facebook!")
                self.performSegueWithIdentifier("login", sender: self)
            
         else 
            println("Uh oh. The user cancelled the Facebook login.")
        
    )

【问题讨论】：

您在 API 中查看并尝试了什么？

parse.com/questions/…

找不到 swift 的任何内容。不了解 Objective C

逻辑一样，类名一般都一样，试试看

【参考方案1】：

考虑到您已经设置了解析和 facebook，点击 Facebook 按钮后，它将如何工作。

    @IBAction func fblogin(sender: AnyObject) 
    var permissions = ["public_profile","email"]
    PFFacebookUtils.logInWithPermissions(permissions, 
        (user: PFUser!, error: NSError!) -> Void in
        if let user = user 
            if user.isNew 
                println("User signed up and logged in through Facebook!")
                var user = PFUser.currentUser()
                self.performSegueWithIdentifier("login", sender: self)
                let defaults = NSUserDefaults.standardUserDefaults()

                FBRequestConnection.startForMeWithCompletionHandler(connection, result, error in
                    println(result.email);
                    PFUser.currentUser().setObject(result.email as String, forKey: "email")
                    PFUser.currentUser().saveInBackground()


                )
                defaults.setBool(true,forKey:"signedup")
                self.performSegueWithIdentifier("login", sender: self)

            else 
                println("User logged in through Facebook!")
                let defaults = NSUserDefaults.standardUserDefaults()
                defaults.setBool(true,forKey:"signedup")
                self.performSegueWithIdentifier("login", sender: self)
            
         else 
            println("Uh oh. The user cancelled the Facebook login.")
        
    )

【讨论】：

您介意添加几句话来解释您的代码应该如何使用吗？

在 PFUser.currentUser().setObject(result.email as String, forKey: "email") 处出现错误

【参考方案2】：

在目标c中，您可以通过这种方式解决您的问题

[PFFacebookUtils logInWithPermissions:permissionsArray
                                block:^(PFUser *user, NSError *error) 
  if (user) 
    [FBRequestConnection startForMeWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) 
      if (!error) 
        // Store the current user's Facebook ID on the user
        [[PFUser currentUser] setObject:[result objectForKey:@"id"]
                                 forKey:@"fbId"];
        [[PFUser currentUser] saveInBackground];
      
    ];
  
];
