Google APIs Client Library for Objective-C

Written by Google, this library is a flexible and efficient Objective-C framework for accessing JSON APIs.

This is the recommended library for accessing JSON-based Google APIs for iOS and Mac OS X applications. The library is compatible with applications built for iOS 3 and later, and Mac OS X 10.5 and later.

To get started with Google APIs and the Objective-C client library, read the introduction and study the example applications.

To browse the library source code, visit the Source tab. Generated interfaces for Google APIs are in the services folder. Library changes are documented in the release notes.

Google APIs with generated interfaces include

The library may also be used without generated interfaces with JSON REST and JSON-RPC APIs.

If you have a problem or want a new feature to be included in the library, please join the discussion group. Be sure to include http logs for requests and responses when posting questions. Bugs may also be submitted on the issues list.

Externally-included projects: The library includes code from the separate projects GTM HTTP Fetcher, GTM OAuth 2, and json-framework.

Google Data APIs: The library for older, XML-based APIs is still available.

More useful classes for Mac and iPhone developers are available in the Google Toolbox for Mac.
