在 SwiftUI 中，当操作表出现时会发生什么？

Question

The default accent color of the button, will automatically change to gray(disabled or un-touchable) when an actionsheet shows up. But with custom accent color, this will not happen.

So what caused this behaviour of the button with default accent color?

Answer 1

I reckon (as I couldn't find one) there's no documentation for it.

But as we can all observe, I believe if you use Color.accentColor in any views, and when an ActionSheet comes up, all views will be enumerated and if such view has Color.accentColor for its any color-able property, that property will be toggled (changed to gray and back to accentColor).

For instance, a ZStack with Color.accentColor .
