Detecting presence of GameKit invitation at application start without authentication

My application, among other features, is going to support real-time multiplayer games using Apple GameKit.


When the application starts, I want to avoid authentication, unless it is needed for playing a game.


Is there a way to find out without authentication if the application was started as a result of accepting an invitation, or just from the desktop?
