Deserializing local NSString of JSON into objects via RestKit (no network download)

Question

Is it possible to deserialize an NSString of JSON into objects via RestKit? I checked the API list here and could not find something that would serve for this p

A more iOS 5+ oriented answer:

NSString* JSONString = jsonString;
NSString* MIMEType = @"application/json";
NSError* error = nil;
id parser = [[RKParserRegistry sharedRegistry] parserForMIMEType:MIMEType];
id parsedData = [parser objectFromString:JSONString error:&error];
if (parsedData == nil && error) {
    NSLog(@"ERROR: JSON parsing error");
}

RKObjectMappingProvider* mappingProvider = [RKObjectManager sharedManager].mappingProvider;
RKObjectMapper* mapper = [RKObjectMapper mapperWithObject:parsedData mappingProvider:mappingProvider];
RKObjectMappingResult* result = [mapper performMapping];
if (result) {

    NSArray *resultArray = result.asCollection;

    MyObject *object = [resultArray lastObject];
    NSLog(@"My Object: %@", object);
}
