this is my json response data. I want to display the six profiles(6 dictionaries) based on the "idprofile" key in a table view with first_name, last_name and the profile image. I am getting confused. Please help?
here's my code:

Answer 1

first you have parse the json. to parse the jason you can use JSONKit

Answer 2

With the help of JSONKIT, first you have to parse response string.
You will get array or dictionary from JSON response. #SmartWork has provided you a link for JSONKIT and How to create JSON Array string given below? will help you out to retrieve array/dictionary from response.
