Facebook SDK 3.0 Beta for iOS now Available for Download


facebook sdk for iOS

Facebook released the beta version of Facebook SDK 3.0 for iOS which allows developers to create Facebook-integrated apps and will automatically use the native Facebook Login in iOS 6 when it becomes available, which will ensure that apps will work seamlessly on all iOS versions 4.0 and later.

Facebook SDK 3.0 Beta new features:

1. Better user session management: In the past, managing auths, user sessions and tokens was hard. We've spent a lot of time working to make these takes easier for you. This release introduces FBSession, which manages, stores and refreshes user tokens with default behaviors you can override. It uses the block metaphor to notify your app when a user's token changes state.

2. Ready-to-Use Native UI Views: This SDK release includes a variety of pre-built user interface (UI) components for common functions. You can quickly drop them into your apps instead of building each one from scratch or using dialogs. This gives you a fast, native and consistent way to build common features.

  • FBProfilePictureView lets you display a user’s profile picture.
  • FBPlacePickerViewController allows users to query the Facebook Places database to find nearby options and check in.
  • FBFriendPickerViewController, with single and multi-selection options, enables users to easily select friends. This supports filtering friends by device type and application authorization status.

3. Modern Objective-C language features support: With Automatic Reference Counting (ARC), you no longer have to spend as much time on memory management. Support for blocks means that it’s now more straightforward to handle sessions and calls to asynchronous Facebook APIs. This, along with inclusion of key language features like idiomatic API naming and KVO, allows you to transition seamlessly between the Facebook SDK and Apple’s iOS environment.

4. Improved Facebook APIs support: We have enabled batching for SDK requests to significantly improve latency for Facebook API calls, which translates to much faster access times for API requests. Support for strongly typed Objective-C types for graph actions and objects makes programming against the social graph more concise and easier. This combined with our action publishing API makes it easier to publish Open Graph actions to people’s timelines

The company has also introduced a new iOS Dev Center that will help developers quickly access tools and resources needed for iOS.
