如何在模拟器 iOS 13 中使用暗模式？

How to use dark mode in simulator iOS 13?

提问by Mr.Javed Multani

While I am developing the iOS app I need to test it in simulator with dark mode option so I can get more clarity about the app UI. But when I go to the Setting I am not getting option for dark mode as real device showing.

在开发 iOS 应用程序时，我需要在模拟器中使用暗模式选项对其进行测试，以便我可以更清楚地了解应用程序 UI。但是当我进入设置时，我没有像真实设备显示那样获得暗模式选项。

在Settings 中，向下滚动到Developer，然后是Dark Appearance...

You can toggle the interface mode (i.e. Light / Dark) as well as adjust dynamic type setting on the fly (when the simulator is running) like this:

您可以切换界面模式（即亮/暗）以及动态调整动态类型设置（当模拟器运行时），如下所示：

Automated Appearance Change

自动外观更改

Xcode 11.4

Xcode 11.4

Apple released a powerful Xcode update which contains some useful things for this topic. Appearance can now be selected directly in the simulator. Just select Features > Toggle Appearanceor ? + ? + A. The automatic appearance switching could stil be important, e.g. for automated screenshot tests on the command line. The script becomes easy like this when using Xcode 11.4:

Apple 发布了一个强大的 Xcode 更新，其中包含有关此主题的一些有用内容。现在可以直接在模拟器中选择外观。只是选择Features > Toggle Appearance或？+ ? + A. 自动外观切换仍然很重要，例如对于命令行上的自动屏幕截图测试。使用 Xcode 11.4 时，脚本变得如此简单：

device_ids=("C741F3CD-FDAC-49EA-A4DB-7F797B97291E" "428183B6-3EB8-4D36-9938-9D07C141BF49")

# The value to use is now just 'dark' or 'light'
appearance=dark

for device in "${device_ids[@]}"; do
  xcrun simctl boot $device
  xcrun simctl ui $device appearance $appearance
done

No more simulator killing or re-setting needed which is a huge performance win. Also no fiddling around with any plist tools anymore - ever. keep in mind that you have to use device ids that are available in the runtime you use. Find them out using xcrun simctl list.

不再需要杀死模拟器或重新设置，这是一个巨大的性能胜利。也不再摆弄任何 plist 工具 - 永远。请记住，您必须使用在您使用的运行时中可用的设备 ID。使用xcrun simctl list.

There is a way using the command line to switch a simulator between light and dark mode. If you have an array with your device IDs you can do the following:

有一种方法可以使用命令行在明暗模式之间切换模拟器。如果您有一个包含设备 ID 的数组，您可以执行以下操作：

device_ids=("C741F3CD-FDAC-49EA-A4DB-7F797B97291E" "428183B6-3EB8-4D36-9938-9D07C141BF49")

# Determine the plist value for the desired style: "dark" -> 2 / "light" -> 1
style=2

for device_id in "${device_ids[@]}"; do
  plist_path="${HOME}/Library/Developer/CoreSimulator/Devices/${device_id}/data/Library/Preferences/com.apple.uikitservices.userInterfaceStyleMode.plist"  
  printf '\n%s' "Set style $style for device $device_id ($plist_path)"

  killall "Simulator"
  xcrun simctl shutdown booted
  xcrun simctl erase $device_id

  # Crate the plist since it might not be available after erase
  [[ ! -f "$plist_path" ]] && /usr/libexec/PlistBuddy -c "save" $plist_path  
  # Set the style mode
  plutil -replace UserInterfaceStyleMode -integer $style $plist_path
done

If you want to specify device names in your script - since device IDs are different on different machines - you can also easily find the id's of them using the following bash code:

如果您想在脚本中指定设备名称 - 因为设备 ID 在不同的机器上是不同的 - 您还可以使用以下 bash 代码轻松找到它们的 ID：

device_names=("iPhone SE" "iPhone 8" "iPhone 11 Pro" "iPhone 11 Pro Max")
device_ids=()

for name in "${device_names[@]}"; do
  id=$(xcrun simctl list --json | jq ".devices | .[] | .[] | select(.name == \"$name\") | .udid" | cut -d\" -f2)
  device_ids+=("$id")
done

printf '%s\n' "${device_ids[@]}"

Alternatively, you can also switch the appearance programmatically (docs):

或者，您也可以以编程方式切换外观 ( docs)：

override func viewDidLoad() {
    super.viewDidLoad()
    #if DEBUG
    // change the appearance only while testing  
    overrideUserInterfaceStyle = .dark
    #endif
}

You can use the "Toggle Appearance" setting from the Simulator menu dropdown (Shift-Command-A):

您可以使用模拟器菜单下拉菜单中的“切换外观”设置（Shift-Command-A）：

There are two ways to enable dark mode in Simulator. Note: Make sure that you're using iOS 13 simulator. X-D

在模拟器中启用暗模式有两种方法。注意：确保您使用的是 iOS 13 模拟器。XD

Solution 1:Change build settings

解决方案 1：更改构建设置

1. Open Settingsapp
2. Select Developer
3. Enable Dark appearance

1. 打开设置应用
2. 选择开发商
3. 启用深色外观

Solution 2:Programmatically

解决方案 2：以编程方式

Simply add this code block in your ViewController file.

只需将此代码块添加到您的 ViewController 文件中。

override func viewDidLoad() {
    super.viewDidLoad()
    #if DEBUG
    // This changes appearance only for debug mode
    overrideUserInterfaceStyle = .dark
    #endif
}

You can also switch Dark mode using this line, you just need to put these lines in your info.plist file

您也可以使用此行切换暗模式，您只需将这些行放在 info.plist 文件中

<key>UIUserInterfaceStyle</key>
<string>Dark</string> //Light
