您可以使用iOS size classes并为纵向和横向指定不同的约束。

Storyboards in Interface Builder by default use size classes. Size classes are traits assigned to user interface elements, like scenes or views. They provide a rough indication of the element’s size. Interface Builder lets you customize many of your layout’s features based on the current size class. The layout then automatically adapts as the size class changes.
