For an iOS app that doesn't exist yet in the App Store, what I should write for "Steps to Reproduce Your Action" when I am submitting the actions for the Facebook Open Graph Api ?
You can submit screenshots of the flow of your app as an acceptable alternative when you have a native mobile app such as this. Specifically, the screenshots should show how the action is triggered within the app and then what the story looks like on a user's Timeline.
Upload the screenshots to some URL and then explain and include the URL with your submission.
