I am creating an iOS app using Flex 4.5 (Flash Builder 5.5) and I want to authorise my user with the Facebook API. Google isn't turning up any answers as to how to do this, and the Facebook documentation obviously only shows you how to do it using Cocoa. Whilst I can obviously make the HTTP request, the Facebook API expects a return uri argument, and I don't want my user to be able to authenticate the app seamlessly like Tweetdeck or other apps that use Facebook.
Has anyone managed to authorise a mobile app build in Flex with Facebook?
