Is there any way to add a 'skip 30 minutes back/forward' button to a subclassed AVPlayerViewController so it looks native (just like play/pause button)?
回答1:
There is actually no 'good' way of doing it. Apple keeps AVPlayerViewController simple and unfortunately unextensible.
The only thing you can do is set a custom overlaying view. But it doesn't solve the problem.
And docs say you shouldn't subclass AVPlayerViewController which means you either use it and accept as it is or write your own controller that manages an instance of AVPlayer and has everything you need.
