Following up with its initial iOS 6 release, Facebook has just released the first update since July for it’s mobile SDK today, version 3.1. You can check out the details and the added tools for the new SDK below if you’re interested in developing mobile apps, or if you’re just a hardcore Facebook fan.

Developers can download SDK 3.1 right here.

Native, ready-to-use UI controls:

The SDK includes several pre-built user interface controls:

-Friend Picker to help apps easily pick friends. Example: use a friend picker to choose friends to tag in an Open Graph action.
-Places Picker so apps can easily integrate with Facebook places. Example: use this picker to let users include a place with their posts.
-Profile Picture control so your app can easily show the profile picture of a user, their friends, places, or other kinds of Facebook objects.
-Login controls for easily building Login and Logout experiences.

Facebook Login support across iOS versions:Lets your app work seamlessly on all iOS versions 4.0+ and integrates easily with the native login support in iOS 6.

Easy session management:Introduces the FBSession API that manages, stores, and refreshes user tokens. You can also override default behaviors to build advanced features. It uses the modern Objective-C “block” metaphor to notify your app of login, logout and other session state changes, and it instantly integrates with iOS 6.

Improved API support:Minimizes the code you need to call Facebook Graph, FQL, and other APIs. It natively supports batched API requests to significantly improve performance for API calls, which translate into faster, better user experiences.

This SDK also contains a beta for Facebook’s new Ad analytics tool. This allows developers to get statistics saying how effective their adds are:

Ad analytics (Beta): Lets you record analytics to give you information about the effectiveness of your ads and understand how people use your app. Learn more about the mobile ads product.
