问题
In my tvOS app, I have a UICollectionView. When I scroll from top to bottom on the Siri Remote, it it moves the view down. This is the opposite of how most Collection Views would work. I want it to behave like a trackpad, when you scroll from bottom to top, have it move the collection view down. How can I invert this scrolling behavior?

You don't want to move away from Apple TV standards. Your goal in making a tvOS application is not to create an entirely different piece of software, but to make your application feel like an extension of the Apple TV. This creates a better user experience when users open your app and everything behaves just as they expect.
