Facebook today provided developers with a handful of new tools that it says will improve the way their apps interact with and pull content from Facebook.
First, Facebook is offering a new API for its Open Graph that makes integrating the Graph with third-party apps much easier for developers. Second, it is improving app log-ins to make it easier for users (and developers) to log into apps with Facebook credentials and still maintain permission and privacy controls. Log-ins should also be faster.
Last, Facebook has published iOS SDK 3.5 for developers. This latest SDK incorporates the changes mentioned above, and includes an updated Developer Center.
