Embedding YouTube video in iOS app?

I need a YouTube video to play inside my iOS app. I know there's a Youtube API for AS3, but I haven't had much luck getting it to work. When I test the app on my computer, I get the error "SecurityError: Error #3207: Application-sandbox content cannot access this feature", and on the iOS device it just does nothing. I have set Security.allowDomain("www.youtube.com").

Does anyone have working example of getting this to work on a mobile device? Or is there another library altogether that I can use?
