iOS How did Facebook put App Store pages in its app)

[moonman239]

I just tapped on an app in Facebook. Facebook then gave me its App Store page. Strangely, the App Store icon is not in my app switcher. I even clicked "free," then "install" just to see if the phone would switch to the native App Store app.

How did they do that?

By linking to the App Store?

moonman239, I must say... You create some very weird threads and posts

I'm guessing it was using SKStoreProductViewController, which is an iOS 6 StoreKit API that lets you bring up a modal controller with an App Store product page.
