Even though the YouTube app is now not a built-in app by Apple, it looks like when tapping a youtube link (in mail, for example), which starts with http://www.youtube.com, opens the YouTube app right away.
Is there a way to this for custom apps in iOS 6? I only know of custom schemes as the way to launch an app via URL.
The best solution i came across is in this post = >
Is it possible to register a http+domain-based URL Scheme for iPhone apps, like YouTube and Maps?
But this is not as good as youtube integration. Requires user interaction via a confirm dialog etc. I wonder if IOS treats youtube links special and custom apps won't be able to use it?
