I want to add a simple button in my iOS game that posts someone's score in their wall, perhaps with a link to the iTunes page of the app.
Do I need to create a Facebook Developer App for this? My problem with this is that apparently the SDK's sharing functionality won't work until the (Facebook) app is approved by the Facebook team, but in order to review the (Facebook) app, the team needs to be able to actually test it - but my game isn't finished and is not on the Appstore yet, so they can't review it...
