Parse data returned from j.mp

I'm currently writing an iPhone application, that posts a开发者_开发问答 long url to j.mp (bit.ly). It is fully working and posts the long url successfully. But when I want to copy the returned data into an UITextView, I just get some JSON Data. Now my question: How can I parse this data, so that I only have the shortened url?

Could anyone help me with this?

There are a number of JSON parsers out there that you can use. One that I've worked with is TouchJSON which performed great.
