为iPhone和iPad Xcode 9指定不同的“查看”宽度

Question

我有一个“视图”，没有为其添加任何宽度，并且在我指定了宽高比的情况下，它在不同的iPhone尺寸下都可以正常工作，但是当我切换到iPad时，“视图”会拉伸以占用iPad的整个空间指定iPad中“视图”的宽度，是否有人做过此事？

Answer 1

You need to disable the aspect ratio constraint for IPad and create a suitable one for it like this

1- Un install the aspect ratio constraint , click the + icon near installed from the popup select Regular for width and height , then click add variation

2- And un Check it for RR

3- Select any IPad device in the bottom Bar , click vary for traits and make the new aspect ratio constraint as you want then click Done varying

By this you have 2 different constraints for the aspect ratio when you run the app in IPhone or Ipad , Note: you can do it for any constraint you want
