Parse this input - ios

Question

I get this text from the quizlet API. But how do I proceed to import it and cut it into usable pieces. I tried NSXMLParser but it didn't work. (Error 111).
How do I parse this input?
I don't need specific instructions, but a hint to where to search would be awesome.

You would use something like this to convert it to a NSDictionary:
NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
Where data would be your response containing JSON. There may be some work involved to tailor up the json so that you get only the portion you want.

Answer 2

Here is my 'hint to where to search' : This is json, check for NSJSONSerialization tuto on the web.
