RESTKit: RKMappingResult with Dictionary

Question

In the image below is the JSON that I'm getting back.

Below is my code mapping:

+(RKMapping *)googleMapping
{
    RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[mappingModel class]];

    [mapping addAttributeMappingsFromDictionary:@{
                                                  @"description" : @"description",
                                                  @"reference" : @"reference"
                                                  }];
    return mapping;
}

Fetch:

RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping
                                                                                            method:RKRequestMethodGET
                                                                                       pathPattern:nil
                                                                                       keyPath:@"predictions" statusCodes:statusCodeSet];
RKObjectRequestOperation *operation = [[RKObjectRequestOperation alloc] initWithRequest:request
                                                                    responseDescriptors:@[responseDescriptor]];

[operation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {

    NSLog(@"mappingResults %@", mappingResult);

} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    NSLog(@"mappingResults Error %@", error);

}];
[operation start];

NSLog:

The mappingResult that returns should be an array with NSDictionary Objects? It seems to return the value of "description" in an array and there is no "reference" value. What am I doing wrong?

Returned JSON:

Answer 1

description is a defined method name, so by adding your own property with the same name you're overriding the default implementation. So, you do have the objects you expect, but the log prints something you aren't expecting.

Change the name of your property so it doesn't overlap with description.
