Yes sure, it is simply the scrumptious app sample …
-- -- Project: Facebook Connect scrumptious sample app -- -- Date: March 14, 2013 -- -- Version: 1.0 -- -- File name: mainScreen.lua -- -- Author: Corona Labs -- -- Abstract: Presents the Facebook Connect login dialog, and then posts to the user's stream -- (Also demonstrates the use of external libraries.) -- -- Demonstrates: Facebook library, widget -- -- File dependencies: facebook.lua -- -- Target devices: Simulator and Device (iOS only) -- -- Comments: -- Requires API key and application secret key from Facebook. To begin, log into your Facebook -- account and add the "Developer" application, from which you can create additional apps. -- -- IMPORTANT: Please ensure your app is compatible with Facebook Single Sign-On or your -- Facebook implementation will fail!
