SwiftUI:在设备上测试时未检测到暗模式

问题描述

我正在尝试使用 SwiftUI 在我的 iOS 应用程序中实现暗模式:简单的测试是更改背景颜色.

I'm am trying to achieve dark mode within my iOS application using SwiftUI: simple test would be to change the background colour.

我已经设置了我的颜色集，如下所示:

I have set up my colour set as seen below:

ContentView.swift:

ContentView.swift:

import SwiftUI

struct ContentView : View {

  @EnvironmentObject var session: SessionStore

  func getUser () {
      session.listen()
  }

  var body: some View {
    Group {
      if (session.session != nil) {
        VStack {
            WelcomeView()
            .background(Color("bg"))
            .edgesIgnoringSafeArea(.all)
        }
      } else {
        VStack {
            SigninView().transition(.move(edge: .bottom))
        }.frame(maxHeight: .infinity)
            .background(Color("bg"))
            .edgesIgnoringSafeArea(.all)
      }
    }.animation(.spring())
    .onAppear(perform: getUser)
  }

}

这不起作用.但是，当在 .onAppear 之后使用 .colorScheme(.dark) 强制暗模式时 - 它可以工作.

This doesn't work. However, when forcing dark mode with .colorScheme(.dark) after .onAppear - it works.

当使用 @Environment (\.colorScheme) var colorScheme:ColorScheme 调试时，它返回 light，即使我的 iPhone 设置为暗模式.

When debugging with @Environment (\.colorScheme) var colorScheme:ColorScheme it returns light, even though my iPhone is set to Dark Mode.

我错过了什么吗?

推荐答案

我想通了.原来用户界面样式在我的 Info.plist 文件中设置为 light - 只需将其删除即可.

I figured it out. Turns out User Interface Style was set to light in my Info.plist file - just delete it.
