Is there some system notification that I can subscribe to be notified when user switches ring/silent button? I would also like to know whether Apple provides some "system notifications list" or not. I've spent an hour searching this but failed.

There is no way to find out that. Apple in response to some request has answered like this

We never have provided a method for detecting hardware mute switch and don't intend to do so.

In case you would try some work around I think Apple will reject your application, however you could request for the feature or report a bug to apple.
