推荐答案

一旦您授权用户并获得访问令牌，您就可以可以快速确定哪些朋友已经授权您的应用程序，并致电 / me / friends？fields = installed

Once you've authorised the user and obtained an access token, you can quickly determine which of their friends have already authorised your app with a call to /me/friends?fields=installed

对于已经授权该应用的用户的朋友，结果将如下所示：

For the users' friends who have already authorised the app, the result will look like this:

{
   "installed": true, 
   "id": "{USER_ID_GOES_HERE}"
}, 

而对于尚未授权该应用的用户，结果将如下所示：

and for the users who have not already authorised the app, the result will look like this:

{
  "id": "{USER_ID_GOES_HERE}"
}, 

在iOS SDK中执行此操作，您将看不到确切的返回值，但SDK应将结果放入可以使用的数据结构中，并检查是否存在已安装项目

If you're doing this in the iOS SDK you won't see that exact return value, but the SDK should put the results into a data structure you can use, and check for the presence of the 'installed' item

您也可以要求添加用户对象字段，而不仅仅是安装，但这只是一个快速例如，向您展示如何获取使用该应用的朋友列表

You can also request additional User object fields other than just 'installed', but this is just a quick example to show you how to get the list of friends that use the app
