Many thanks are in order for George Fletcher. He has just released a port of the OAuthConsumer framework for Tiger. Any of you who might be working on 10.4 apps can now take advantage of OAuth. The port is 100% API-compatible with the original Leopard version so the docs apply to both frameworks.
Thanks for sharing, George!
The OAuth Spec was just updated to Draft 6, and the Mac OAuthConsumer framework has been updated to match. The framework has now been successfully tested with two live endpoints — Ma.gnolia, and term.ie, both Draft 6 compatible as well.
I have just published Using OAuthConsumer, a complete guide to using the OAuthConsumer framework for Mac apps. It is part of the Google Code project wiki.
Questions and comments from interested developers are welcome.
