Facebook released their iOS SDK today which brings iOS 6 integration along for developers to integrate on their apps.
One of the most important things this iOS 6 integration brings is the native Facebook login, which makes it quicker to log in to Facebook than current methods make it possible.
Improved Facebook API makes it faster when making calls to Facebook's API as batching has been enabled for SDK requests.
The iOS SDK 3.0 offers pre-built native UI views so developers don't have to built them. Some of these include Profile Picture view, Facebook Places picker and Friend select options.
Modern Objective-C language makes it easy for apps to transition between the Facebook SDK to iOS environment.
Also, Facebook updated their iOS Development Center with tutorials, reference docs and concepts.
