It's been quite a while since Facebook last updated its iOS SDK. The last update came out around the launch of the iPhone 5 to include support for iOS 6. The latest SDK update doesn't have a major iOS update to piggyback on, but it includes a number of features that iOS developers will surely appreciate.
Facebook announced that version 3.2 of its SDK for iOS is now available to developers everywhere. The big update this time around is better mobile analytics so iOS app developers can get a better idea of how well their app's Facebook integration is working out.
Mobile analytics now include a number of new metrics and features that will help you get the most out of it:
Aside from additions to analytics, the new SDK features enhanced error handling. In short, all classes of error responses will now receive SDK support and documentation. Facebook says that the "SDK will now automatically categorize errors by common application handling behavior and provide helpers to simplify some common error response cases." Version 3.2 will also handle a larger number error cases, including those introduced in iOS 6.
Version 3.2 also adds improved Web dialog support and improvements to the API. For Web dialog improvements, the SDK now integrates Web, Feed and Requests dialogs without invoking deprecated headers. As for API improvements, Facebook is adding a new FBAccessTokenData type that should make it easier to open a session from token data.
