Question

如何使用新的facebook api获取我朋友朋友列表的列表。我使用以下代码获得了好友列表，

$friends = $facebook->api('/uid/friends');

但是如果我在同一个函数中传递了他们的用户ID，我就无法得到朋友列表。

Answer 1

你不能，这是他们的私人数据，所以它在他们的控制之下。如果他们希望应用程序可以访问它，他们就会授予权限，并且可以代表他们这样做。

Answer 2

facebook朋友列表只有可标记的朋友列表获取。

Facebook无法访问完整的个人资料朋友列表，只显示您的个人资料中的总朋友列表编号。

pod和plist设置所有其他应该是你的Facebook开发人员步骤适用

所以这里我的代码在swift 3.0可标记好友列表中：

//appdelegate.swift


import CoreData
import FBSDKCoreKit
import FBSDKLoginKit
  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
         return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
        // Override point for customization after application launch.
        return true
    }

    func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
        return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, options: options)
    }
