iOS Facebook Api，对评论帖子点赞

Question

我想在 Facebook 上点赞帖子的评论，我使用与点赞帖子相同的方法。对于一个帖子，它有效，但对于一个评论失败。

文档: https://developers.facebook.com/docs/graph-api/reference/object/likes

我的代码:

[FBRequestConnection startWithGraphPath:[NSString stringWithFormat:@"/%@/likes", postId_]
                             parameters:nil
                             HTTPMethod:@"POST"
                      completionHandler:^(FBRequestConnection *connection, id result, NSError *error)
                        {  //Error:
                        }];

错误是:

Error Domain=com.facebook.sdk Code=5 "The operation couldn’t be completed. (com.facebook.sdk error 5.)" UserInfo=0x158999b0 {com.facebook.sdk:HTTPStatusCode=400, com.facebook.sdk:ParsedJSONResponseKey={ body = { error = { code = 100; message = "(#100) Error finding the requested story"; type = OAuthException; }; }; code = 400; }, com.facebook.sdk:ErrorSessionKey=}

我是这样做的，效果很好

    // post is my module object, encapsulates the info form the post
    // pass the post ID
    NSString *graphPath = [NSString stringWithFormat:@"%@/likes", post.postID];

    FBRequest *request = [FBRequest requestForGraphPath:graphPath];
    // DELETE or POST the like
    NSString *method = post.liked?@"DELETE":@"POST";
    [request setHTTPMethod:method];

    [request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
        BOOL success = YES;
        success = (error)?NO:YES;
        if(success) {

        }
    }];
