So I've been programming a Drupal for iPhone app using XMLRPC. I got it working, yeh!
It's a little rough around the edges but things users can do so far...
- Input any drupal website. The drupal services module needs to be installed. Well at least I haven't tested it without the services module. The session module needs sessid checked.
- Login with your drupal username/password.
- Post a title and story to your drupal website.
- Logout.
- The list of features I want to add is pretty long, but at least this basic part is working.
