Various JSON parsers exist for objective c. You'll have to pass the data to a library or to javascript in a webview to extract it. Here is a google library: http://code.google.com/p/json-framework/

If you need help with saving the data, I say with no snideness whatsoever that you should read the manual: http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/CoreData/Articles/cdUsingMOM.html
