ios - Facebook iOS sdk 好友列表返回空

Question

我正在使用此代码在 iOS sdk 8.1 中获取 Facebook 好友列表。

FBRequest* friendsRequest = [FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
                              NSDictionary* result,
                              NSError *error) {
    NSArray* friends = [result objectForKey:@"data"];
    NSLog(@"Found: %lu friends", (unsigned long)friends.count);
    for (NSDictionary<FBGraphUser>* friend in friends) {
       NSLog(@"I have a friend named %@ with id %@", friend.name, friend.objectID);
     }
}]; 

但它返回空值。

从 Graph API v2.0 开始，/{user_id}/friends 端点只会返回那些也向您的应用授予相应权限的 friend 。

The /me/friends endpoint no longer includes the full list of a person's friends. Instead, it now returns the list of that person's friends who are also using your app.
