Facebook SDK 3.5 for the platform iOS offers application developers the opportunity to implement a native Share Dialog that allows sharing content from iDevices without much effort. Those at Facebook have implemented the possibility of introducing the sharing system in applications through a single line of code, with developers having much less work to offer such functionality through their own applications.
The Share Dialog further improves upon the iOS 6 share sheet by adding support for publishing Open Graph actions to make it easier for people to tell their stories on mobile. In addition, people can now tag friends and share where they are enabling them to share in a more meaningful and engaging way, while helping even more people connect with your app.
Any developers can implement this functionality and if you are interested in learning more about it, then it is recommended to read this documentation.
