How to publish 'X is playing MyGame' on news ticker in Facebook?

Question

When my friends are playing Facebook-based games, I see "Friend's Name is playing Game's Name" in the news ticker. How can I achieve the same functionality for an iOS Game? Is there a special way of doing this, or is it just done using the Open Graph actions and objects?

Those are automatic 'discovery stories' - you can't post them manually
