Run react-native application on iOS device directly from command line?
提问by Aakash Sigdel
Is it possible to run react-native application on an iOS device directly from the command line like we do on simulator with react-native run ios --simulator "iPhone 5s"?
是否可以像我们在模拟器上那样直接从命令行在 iOS 设备上运行 react-native 应用程序react-native run ios --simulator "iPhone 5s"？

The following worked for me (tested on react native 0.38and 0.40):
以下对我有用（在 react native0.38和上测试0.40）：
npm install -g ios-deploy
# Run on a connected device, e.g. Max's iPhone:
react-native run-ios --device "Max's iPhone"
If you try to run run-ios, you will see that the script recommends to do npm install -g ios-deploywhen it reach install step after building.
如果您尝试运行run-ios，您将看到脚本npm install -g ios-deploy在构建后到达安装步骤时建议执行。
While the documentation on the various commands that react-native offers is a little sketchy, it is worth going to react-native/local-cli. There, you can see all the commands available and the code that they run - you can thus work out what switches are available for undocumented commands.
虽然 react-native 提供的各种命令的文档有点粗略，但值得去react-native/local-cli。在那里，您可以看到所有可用的命令以及它们运行的代码——因此您可以确定哪些开关可用于未记录的命令。

First install the required library globally on your computer:
首先在您的计算机上全局安装所需的库：
npm install -g ios-deploy
Go to your settings on your iPhone to find the name of the device.
转到 iPhone 上的设置以查找设备名称。
Then provide that below like:
然后提供如下：
react-native run-ios --device "______\'s iPhone"
Sometimes this will fail and output a message like this:
有时这会失败并输出如下消息：
Found Xcode project ________.xcodeproj
Could not find device with the name: "_______'s iPhone".
Choose one of the following:
______'s iPhone Udid: _________
That udid is used like this:
那个 udid 是这样使用的：
react-native run-ios --device --udid 0412e2c230a14e23451699
Optionally you may use:
您可以选择使用：
react-native run-ios --device --udid 0412e2c230a14e23451699 -- configuration Release

wait and watch to run your app in specific devices - K00L ;)

After following the steps, I still got an error,
按照步骤操作后还是报错
error Could not find device with the name: "....'s Xr"
错误找不到名称为“....'s Xr”的设备
After removing special characters from the device name (Go to Settings -> General -> About -> Name)
从设备名称中删除特殊字符后（转到Settings -> General -> About -> Name）
Eg: '
例如：'
