The YAJL framework is an Objective-C framework for the YAJL SAX-style JSON parser.

• Stream parsing, comments in JSON, better error messages.
• Parse directly from NSString or NSData.
• Generate JSON from default or custom types.
• Properly handles large numeric types.
• Document style parser.
• Error by exception or out error.

• The online API documentation.

• Copy YAJL.framework to your project directory (maybe in MyProject/Frameworks/.)
• Add the YAJL.framework files (from MyProject/Frameworks/) to your target.
• In Build Settings, add @loader_path/../Frameworks to Runpath Search Paths. If you don't see Runpath Search Paths make sure All is selected instead of 'Basic'.
• In Build Phases, select Add Build Phase, then Add Copy Files.

  • Make sure the copy phase appears before any Run Script phases
• Import with #import <YAJL/YAJL.h>.
• See the API documentation

• Copy YAJL.framework to your project directory (maybe in MyProject/Frameworks/.)
• Add the YAJL.framework files (from MyProject/Frameworks/) to your target. It should be visible as a Linked Framework in the target.
• Under Build Settings, add @loader_path/../Frameworks to Runpath Search Paths
• Add New Build Phase | New Copy Files Build Phase.
  • Change the Destination to Frameworks.
  • Drag YAJL.framework into the the build phase

  • Under Framework Search Paths make sure the (parent) directory to YAJLiOS.framework is listed.
  • Under Other Linker Flags in your target, add -ObjC and -all_load
• Import with #import <YAJLiOS/YAJL.h>.
