ios - RestKit: How to handle empty response.body?

Question

I request something with POST, and the server just sends status-code 200 with a content-length of 0 back. How can I handle this? I'm not allowed to add a RKResponseDescriptor without mapping, nor not add the RKResponseDescriptor.

Ah, I just found out, you can create a mapping for the NSNull class. That seems to work. Here's the code:

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

        [restObjectManager addResponseDescriptor:response];
    }

Please tell me if this is the right way.
