You should use

NSJSONSerialization

It will automatically take care of parsing and will return you a dictionary of array objects. The objects within the Dictionary can be accessed using key value pair.

NSDictionary* json = [NSJSONSerialization
                      JSONObjectWithData:yourjsonData
                      options:kNilOptions
                      error:&error];
