iOS 使用因 iPhone 尺寸之间的特征而异

问题描述

我有一个按钮，我想根据所使用的 iPhone 设置不同的宽度.显然 7 Plus 的宽度更大，而线下的宽度更小.我单击按钮，单击 Vary for Traits，选择 Height，更改每个 iPhone 的约束，然后单击 Done Varying 并构建，但无论我在哪个设备上运行它，它始终保留我最后编辑的约束.

I have a button that I want to be different widths depending on which kind of iPhone is being used. Obviously a larger width for the 7 Plus, and smaller on down the line. I click the button, click Vary for Traits, choose Height, change constraints for each iPhone, then click Done Varying and build, but it always keeps whatever the last constraint I edited was, no matter which device I run it on.

推荐答案

Vary For Traits 与不同的 iPhone 尺寸无关.所有 iPhone(纵向)都具有相同的特征；没有什么可改变的.

Vary For Traits has nothing to do with different iPhone sizes. All iPhones (in portrait) have identical traits; there is nothing to vary.
