When opening Game Center in my iOS app, I see a Facebook like button which is grayed out. Beneath the button is the text: "Facebook Liking Unavailable". My question is: how do I enable Facebook liking, and how do I specify which page will get the like? Do I have to put my app's Facebook URL into the code somewhere?
Are your settings in Settings | Facebook current so that you are authenticated? FWIK that should be all there is to it.
