I successfully integrated Facebook SDK 3.1 in my app, and I'm trying to propose iOS6+ only features to iOS6+ users. I was able to show the share sheet, but I was quite disapointed when I saw what the post on my wall looked like. Here is an image to describe what I mean :

The first one is what is got from a pre-iOS6 dialog (the web popup), and the second one is got from the new iOS6+ Native Facebook Dialog (SLComposeViewController, in other words).
My questions are :
Is there a way to make the second post look like the first one using FacebookNativeDialog ? Is it possible to give a params Dictionary like before so the post will display correctly "via {myAppName}" ? Or is it simply the new way of showing posts, and the older way is deprecated ?
