Facebook is continuing its push to spread Open Graph to every corner of the web (including mobile) with a new version of the Facebook SDK for iOS.
The new SDK (software development kit) gives iPhone, iPad and iPod touch developers easier access to Facebook's massively ambitious Open Graph API. Launched at Facebook's F8 conference earlier this year, the Open Graph protocol makes it easier for third-party websites to integrate Facebook functions onto their webpages, most prominently the now-ubiquitous "Like" button.
The new devkit comes with a second major addition: support for Facebook OAuth 2.0. It replaces Facebook Connect, which is being phased out in favor of the OAuth open standard.
