This is a lightweight JSON library for Objective-C. It works on the iPhone and on the desktop. Most JSON parsers are NSScanner based which has a fair amount of overhead. I don't claim that this is the absolute fastest, but it is very lightweight.
The parser is written as a recursive descent parser, meaning that if you have extremely nested JSON, it is possible to run out of stack space. It is possible to convert this to a stack based parser instead of recursion, but all of my uses are from trusted sources. Additionally, at least two of the other popular JSON libraries also hinge on recursion.
This library currently does not have a JSON Generator, but that will be coming soon.
