For simplicity the Rest API, sends this JSON response-body= { "status" : "ok"}.

I set-up my Restkit mappings like... created a Class called StatusResponse which has one @property (nonatomic, assign) NSString *status;

RKObjectMapping *statusResponseMapping = [RKObjectMapping mappingForClass:[StatusResponse class]];
    [statusResponseMapping addAttributeMappingsFromDictionary:@{@"status":@"status"}]; 

// also tried : [statusResponseMapping addAttributeMappingsFromDictionary:@[@"status"]]; which resulted in same error

    NSIndexSet *statusCodes = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful);

RKResponseDescriptor *statusResponseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:statusResponseMapping method:RKRequestMethodPOST pathPattern:@"status" keyPath:nil statusCodes:statusCodes];

[[RKObjectManager sharedManager] addResponseDescriptor:statusResponseDescriptor];

I'm running a post which is successful, but I get this error back:

NSUnderlyingError=0x17024d440 "No mappable object representations were found at the key paths searched.", keyPath=null, NSLocalizedDescription=No response descriptors match the response loaded.}
response.body={
  "status": "ok"
}

Any help with this would be appreciated.

You should try keyPath to @"" and pathPattern as nil, here is piece of Code I am using which is perfectly working fine for me. I am doing exactly same you are trying to do.

RKResponseDescriptor *statusResponseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:[ResponseStatus rkObjectMappingForResponse:YES] method:RKRequestMethodAny pathPattern:nil keyPath:@"" statusCodes:statusCodes];

  • Apologies for delayed response. I'm going to try your suggestion. Thanks for sharing. I will let you know my results. – user3337849 May 05 '14 at 22:00

Because your response descriptor has pathPattern:@"status", the mapping will only be used when you make a request to the status path on your server. That probably isn't what you want.

You should probably use pathPattern:nil.

  • I have attempted with pathPattern: Nil without success. I need to know how to create the ObjectMapping for simple JSON object {"status" : "ok"} which does not have a keyPath. When I simple attempt to with keyPath: @"status" I get error key-value coding violation. I have been reading RestKit git wiki on ObjectMapping, but they do not show a how to for this simple case. Do you have a reference that you could point me to? – user3337849 Apr 17 '14 at 14:04
