我正在使用 FQL 来确定用户是否喜欢某个帖子。当用户没有喜欢任何帖子时，响应已经足够好，但是当帖子被点赞时它保持不变，我没有得到用户（我的）user_id的响应。

这是我所做的：（在获得read_stream许可后在授予的块内）

NSURL *requestURL = [NSURL URLWithString:@"https://graph.facebook.com/fql"];
    NSMutableDictionary * params = [NSMutableDictionary
                                    dictionaryWithObjectsAndKeys:[NSString stringWithFormat:@"select user_id from like where object_id=%@ AND user_id=me()",postID], @"q", nil];
    SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                            requestMethod:SLRequestMethodGET
                                                      URL:requestURL
                                               parameters:params];
    request.account = [[self.accountStore accountsWithAccountType:accountTypeFacebook] objectAtIndex:0];
    [request performRequestWithHandler:^(NSData *data,
                                         NSHTTPURLResponse *response,
                                         NSError *error) {

        if(!error){
            NSDictionary *resultDictionary = [[NSDictionary alloc] init];
            resultDictionary = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
            NSLog(@"dictionary with user id's: %@",resultDictionary);
        }else{
          //handle error gracefully
        }
     }];

输出（不喜欢帖子时）：

{
    data =     (
    );
}

输出（当帖子被喜欢时）：

{
    data =     (
    );
}

我尝试使用post_idinplace of传递帖子的 id 和查询object_id，但没有成功。

To check whether user liked a post we need to get data form stream table instead of like table, please follow the below request 

Request : 
NSURL *requestURL = [NSURL URLWithString:@"https://graph.facebook.com/fql"];
                                                       NSMutableDictionary * params1 = [NSMutableDictionary
                                                                                        dictionaryWithObjectsAndKeys:[NSString stringWithFormat:@"SELECT likes FROM stream WHERE post_id = '%@'",postID], @"q",facebookOfflineAccessToken,@"accessToken",nil];

Response : you will get "user_likes" = 0 for not liked,"user_likes" = 1 for like
