【问题描述】：

我正在使用 Facebook 实现社交登录。 我使用以下代码记录用户并“检索”与他的帐户相关的信息（我希望），

PFFacebookUtils.logInInBackgroundWithReadPermissions(["public_profile", "email", "user_friends"]) 
  (user: PFUser?, error: NSError?) -> Void in
  if let user = user 
    if user.isNew 
      print("User signed up and logged in through Facebook!")
     else 
      print("User logged in through Facebook!")
    
   
  print(user)
  else 
    print("Uh oh. The user cancelled the Facebook login.")
  

但控制台输出（和要解析的浏览数据）仅显示一个 ID，没有与此 Facebook 帐户相关联的信息。

我读到要获取用户详细信息，我必须在登录请求后发送 FBSDKGraphRequest。 如果是这样，beetwin 在 Parse 实现中使用登录而不是链接有什么区别（以及优势是什么）？

有没有办法在登录操作后自动导入与“权限”Facebook 帐户相关的信息？

提前谢谢你， 米歇尔

只需根据您的需要编辑读取权限，我没有使用 PFF，但 FBSDK 为我完成了工作，希望它对您有用
