iPhone JSON Retreving Value

Hi I am passing one api and getting the response from the server

[{\"Latitude\":\"34\",\"Longitude\":\"45\"},{\"Latitude\":\"46\",\"Longitude\":\"45\"},{\"Latitude\":\"73\",\"Longi开发者_StackOverflowtude\":\"54\"}]

however i didn't know how to break the response which i have got from server into array, so that i can store the values and used it..

It's standard JSON. Lots of libraries out there that do exactly that. I would recommend SBJSON.

to expend on MarPowell answer - this is JSON check out the JSON website - http://www.json.org/
