SBJson (aka json-framework)

JSON (JavaScript Object Notation) is a light-weight data interchange
format that's easy to read and write for humans and computers alike.
This library implements strict JSON parsing and generation in
Objective-C.

Features

• BSD license
• Super-simple high-level API:
  • Call [str JSONValue] on any NSString instance to parse its JSON text
  • Call [obj JSONRepresentation] on any NSArray or NSDictionary to return its JSON text
• Good balance between simplicity and flexibility provided by the SBJsonParser and SBJsonWriter classes
• Configurable recursion depth limit
• Garbage Collection
• Automatic Reference Counting (ARC)
• Optionally sort dictionary keys in JSON output
• Optional pretty-printing of JSON output

Changes in comparison to the original SBJson repo

• Support for converting NSDate to JSON text (as a string with seconds since epoc)
