If you are developing for an Apple device that is accessing services that return JSON data then this parser may be of use for you.
JSON (http://www.json.org/) is a prevalent data format that represents data and objects in a very simple text based format.
The parser development is still in its infancy, but is currently a fully functional JSON Parser that converts the JSON into Cocoa objects.
If you are interested in joining the development or simply using the parser then please join the following Code Exchange Project.
It is very simply to use right now, just copy the .m and .h files to your project and invoke the parser.
