如何使用向左或向右滑动实现3D Touch预览操作？

Question

I know how to add UIPreviewActionItem when swipe from the bottom. There is a method previewActionItems() . But how to do the following thing:

Answer 1

Left and right swipe is a custom implementation by Apple engineers. Broke my heart when I found that out as well.

Answer 2

As Apple's documentation says:

Provide peek quick actions, if appropriate. Within a peek, users can swipe up to reveal actions that are related to the item.

There is nothing about left/right swipe.
