There are couple of JSON frameworks. JSONKit , SBJSON , Native JSON and other. Which one is the best to use for Iphone app OR ios App and why ?
I have used SBJson for two years, and many Object-C API use SBJson too. It is quite hard to compare different json apis, however SBJson is easy to use and widely used.
if you want to target just iOS5 and above you could try NSJSONSerialization
Basically iOS 5 has a new class named NSJSONSerialization. It has a static method called JSONObjectWithData:options:error that takes an NSData and gives you back a Foundation object – usually an NSDictionary or an NSArray depending what do you have at the top of your JSON file hierarchy.
an excellent example
