iphone – 使用批处理请求在Facebook上上传多张照片

我有一些解决方案，上传多张照片在Facebook通过这个Facebook graph API.

码：

NSString *jsonrequest1 = @"{ \"method\": \"POST\",\"relative_url\": \"me/photos\",\"body\": \"Hello 1\",\"attached_files\": \"file1\" }";
    NSString *jsonrequest2 = @"{ \"method\": \"POST\",\"body\": \"Hello 2\",\"attached_files\": \"file2\" }";
    NSString *jsonrequestsArray = [NSString StringWithFormat:@"[ %@,%@ ]",jsonrequest1,jsonrequest2];
    NSMutableDictionary *params = [NSMutableDictionary DictionaryWithObjectsAndKeys:jsonrequestsArray,@"batch",nil];
    [params setObject:UIImagePNGRepresentation(self.image1) forKey:@"file1"];
    [params setObject:UIImagePNGRepresentation(self.image@R_674_11121@orKey:@"file2"];
    [objFacebook requestWithGraPHPath:@"me" andParams:params andhttpR_401_11845@ethod:@"POST" andDelegate:self];

现在当我运行这个代码，我得到以下输出。

结果字典在 – (void)request：(FBrequest *)request didLoad：(id)result

(
        {
        body = "{\"error\":0,\"error_description\":\"File file1 has not been attached\"}";
        code = 400;
        headers =         (
                        {
                name = "http/1.1";
                value = "400 Bad request";
            },{
                name = "Content-Type";
                value = "text/javascript; charset=UTF-8";
            }
        );
    },{
        body = "{\"error\":0,\"error_description\":\"File file2 has not been attached\"}";
        code = 400;
        headers =         (
                        {
                name = "http/1.1";
                value = "400 Bad request";
            },{
                name = "Content-Type";
                value = "text/javascript; charset=UTF-8";
            }
        );
    }
)

我不知道这个文件如何附加..任何人都可以帮助我找出这个问题。

我的代码有任何变化，那么请让我知道。

提前致谢…
