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.
The Facebook SDK for iOS brings that functionality to millions of iOS devices, but the SDK is really for the iPhone and iPad apps that want to beef up their social functionality. Three months ago, the social network launched the Facebook SDK for Android, which brought the same features to Android app developers.
