The fastest JSON parser and serializer for Objective-C.
KSJSON is simply the fastest Objective-C based JSON converter there is. Benchmarks are available at https://github.com/kstenerud/JSONCompare
There are two files to add to your project: KSJSON.h and KSJSON.m.
There are two API calls: serializeObject and deserializeString. That's it.
No extra dependencies. No special include paths. No extra linker options. No pollution of NSArray and friends with helper categories that might clash with another library.
KSJSON includes 70 unit tests, which have 90% code coverage.
KSJSON compiles cleanly with ALL warnings enabled (including pedantic).
The armv7 object code for KSJSON weighs in at 42 kilobytes.
KSJSON supports compiling with or without ARC.
Copy KSJSON.h and KSJSON.m into your project.
NSError* error;
id container = [somewhere getContainer];
NSString* jsonString = [KSJSON serializeObject:container error:&error];
NSError* error;
NSString* jsonString = [somewhere getJSONString];
id container = [KSJSON deserializeString:jsonString error:&error];
