Cocoa-Touch - How parse local Json file

Question

I\'m newbie in iOS dev and I\'m trying to parse a local Json file such as

{\"quizz\":[{\"id\":\"1\",\"Q1\":\"When Mickey was born\",\"R1\":\"1920\",\"R2\":\"1

Answer 1

Use jsonlint.com to find errors in your JSON string.
In this case, it says you have non-valid JSON near "R4"
