ios - ionic 电容器 iOS 不尊重黑暗模式

Question

我有一个使用 @media (prefers-color-scheme: dark) 的 Ionic 应用程序，当我使用电容器构建 ios 版本时，它不支持暗模式。我试过这个node module , looked here , and here ，但似乎没有任何效果。为什么 Capacitor 不支持 iOS 上的深色模式？

应该是什么样子。

Answer 1

这有点棘手，因为深色模式的框架文档不是很清楚，而且在某些地方实际上是不正确的。他们也有一个已知的暗模式逻辑错误。

基本上，您需要自己将 CSS 添加到类级别的 variables.scss 文件中。

如果您直接在 @media 设置下方添加:

ion-card {
  --background: #141414;
}

那应该会改变你的卡片颜色。将适当的类应用于未在暗模式下显示的每个其他元素(即您的工具栏)。
