Answer 2

Checkout this JSON framework for Objective-C on code.google.com or on Github.

It is pretty straightforward to use. You instantiate your SBJSON object then call objectWithString with your buffer:

SBJSON * parser = [[SBJSON alloc] init];
NSString * buffer = @"{"name":"WFNX"}";
NSError* error = NULL;
// the type of json will depend on the JSON data in buffer, in this case, it will be 
// and NSDictionary with one key/value pair "name"->"WFNX"
id json = [parser objectWithString:buffer error:&error];
