Changes

Summary
iOS 6 introduced both the UIActivityViewController class and Social Framework, both of which may be used to integrate Twitter, Facebook and Sina Weibo functionality into iOS 6 applications.
For general purpose requirements, the UIActivityViewController and SLComposeViewController classes provide an easy to implement path to social network integration. For more complex requirements, however, the SLRequest class may be used in conjunction with the Accounts framework to access social network accounts and construct and submit HTTP requests to supported social network APIs.  This chapter provided an overview of the UIActivityViewController and SLComposeViewController classes and outlined the steps necessary to deploy them in applications. The next chapter, entitled An iPhone iOS 6 Facebook Integration Tutorial using UIActivityViewController will work through the development of an example application using the UIActivityViewController class to implement Facebook integration into an iOS 6 based iPhone app. The concepts behind the SLRequest class will be covered in iPhone iOS 6 Facebook and Twitter Integration Tutorial using SLRequest.
