Performing a POST in RestKit without all the fiddly object mapping stuff

RestKitPost.m

NSDictionary* dict = @{@"Status": newStatus ? @"On" : @"Off"};
    
    NSString* url = @"/api/status";
    [[RKClient sharedClient] post:url usingBlock:^(RKRequest *request) {
        [request setBody:dict forMIMEType:RKMIMETypeJSON];
        
        request.onDidLoadResponse = ^(RKResponse* response) {
            NSLog(@"status ok %@", response); 
            
            if (completion) {
                completion(nil);
            }
        };
        request.onDidFailLoadWithError = ^(NSError* error) {
            NSLog(@"status error %@", error);
            
            if (completion) {
                completion(error);
            }
        };
    }];
