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

Answer 1

Judging by the views without any answers, it seems this facility does not exist in RestKit yet. Instead of spending more time trying to figure out how to do the mapping, I wrote my own mapper using the output of JsonKit parser and removed the dependency on RestKit (used the builtin classes for network activity). Right now my mapper is not generic (it has a few dependencies on how the objects are laid out and their names in json) but it works for the purposes of the project. I might come back later and turn it into a more generic object mapping library later on.
