RestKit:如何处理空的response.body？

Question

我用POST请求一些东西,服务器只发送内容长度为0的状态码200.我怎么处理这个？我不允许在没有映射的情况下添加RKResponseDescriptor,也不允许添加RKResponseDescriptor.

啊,我刚刚发现,你可以为NSNull类创建一个映射.这似乎有效.这是代码:

    {
        RKObjectMapping* responseMapping = [RKObjectMapping mappingForClass:[NSNull class]];
        RKResponseDescriptor* response =
        [RKResponseDescriptor responseDescriptorWithMapping:responseMapping
                                                     method:RKRequestMethodAny
                                                pathPattern:@"entry/sync"
                                                    keyPath:nil
                                                statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

        [restObjectManager addResponseDescriptor:response];
    }

请告诉我这是否正确.
