Looking for a JSON tutorial

[mistergreen2011]

Hey,
I'm looking for a ios 5 json tutorial but with some restrictions. The resulting json is fairly large so dumping all the content into an array will probably cause a memory crash. So maybe a selective parsing?

I would also like it not to have it dependent on an internet connection, so I can drag a json file into the app bundle and that the app read that instead of a url?

thanks.
