I'm about finished with a native iPhone app, but I need to finish SSO via Facebook. Despite my best effort, I am unable to figure-out what value is supposed to go in the "iPhone App Store ID" field during the process where I register my app with Facebook on their website.
I have an "App ID" at http://developer.apple.com/ios/manage/bundles/, but Facebook gives me the error "iPhone App Store ID must be an integer" when I put my App ID in that field. My App ID is not an integer.
I know Facebook specifically labels the field with "App Store"; please tell me that isn't really the case, since... how would anyone have something on the "App Store" if it's still in development?
Everyone has "that issue" that motivates their first Stack Overflow post, and this is mine. I eagerly await news that I'm missing something.
Create a new app in iTunes Connect. That app will have a unique app id. That's the id they want. That is, in fact, the App Store id for the app.
