Question

在iOS facebooks SDK中，我想获取facebook用户ID，朋友姓名和图片网址（用户个人资料图片）。

问题：

我使用过FBFriendPickerViewController，它显示了朋友的名字，但是我有办法获取图片网址和脸书ID。
也是FBFriendPickerViewController实际列出好友列表的正确方法。或者我应该使用不同的API。

Answer 1

FBRequest* friendsRequest = [FBRequest requestForMyFriends];

[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,NSDictionary* result,NSError *error)
 {
     NSArray* friends = [result objectForKey:@"data"];

     for (NSDictionary<FBGraphUser>* friend in friends)
     {
         NSLog(@"friend id = %@", friend.id);
         NSLog(@"friend name = %@", friend.username);
         NSLog(@"friend pic url = %@", [NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?", friend.id]);

     }
 }];
