Question

当我运行此命令时：

react-native run-ios

我的应用默认在iPhone6模拟器设备中运行：

Found Xcode project RN.xcodeproj
Launching iPhone 6 (9.2)...

默认情况下，如何让应用程序在不同的模拟器设备（如iPhone5s）中运行？

Answer 1

使用--simulator标志指定模拟器。

这些是iOS 12.0的可用设备：

react-native run-ios --simulator="iPhone 5s"
react-native run-ios --simulator="iPhone 6"
react-native run-ios --simulator="iPhone 6 Plus"
react-native run-ios --simulator="iPhone 6s"
react-native run-ios --simulator="iPhone 6s Plus"
react-native run-ios --simulator="iPhone 7"
react-native run-ios --simulator="iPhone 7 Plus"
react-native run-ios --simulator="iPhone 8"
react-native run-ios --simulator="iPhone 8 Plus"
react-native run-ios --simulator="iPhone SE"
react-native run-ios --simulator="iPhone X"
react-native run-ios --simulator="iPhone XR"
react-native run-ios --simulator="iPhone XS"
react-native run-ios --simulator="iPhone XS Max"
react-native run-ios --simulator="iPad Air"
react-native run-ios --simulator="iPad Air 2"
react-native run-ios --simulator="iPad"
react-native run-ios --simulator="iPad Pro"
react-native run-ios --simulator="iPad Pro"
react-native run-ios --simulator="iPad Pro"
react-native run-ios --simulator="iPad Pro"
react-native run-ios --simulator="iPad"

列出所有可用的iOS设备：

xcrun simctl list devices

目前无法设置默认值。

React Native Docs: Running On Simulator

Answer 2

您还可以通过向scripts文件的package.json元素添加条目来使用 npm 。 E.g。

"launch-ios": "react-native run-ios --simulator \"iPad Air 2\""

然后使用它：npm run launch-ios

Answer 3

您可以在version: '2' services: app1: image: 'mhart/alpine-node:6.3.0' container_name: app1 command: npm start app2: image: 'mhart/alpine-node:6.3.0' container_name: app2 command: npm start # databases [...]文件中创建别名：

~/.bash_profile

然后使用创建的别名运行react-native：

alias rn-ios="react-native run-ios --simulator \"iPhone 5s (10.0)\""

Answer 4

如果你追捕，有一个项目设置：

{project}/node_modules/react-native/local-cli/runIOS/runIOS.js

module.exports下有一些选项，包括：

options: [{ command: '--simulator [string]', description: 'Explicitly set simulator to use', default: 'iPhone 7', }

我的是第231行，只需将其设置为有效的已安装模拟器并运行即可 react-native run-ios默认情况下它将运行到该模拟器。

Answer 5

1）重命名您的模拟器，如果模拟器名称相同但iOS版本不同

Xcode -> Window -> Devices and Simulators -> Simulators.

2）打开您的react native项目文件夹

3）修改 package.json

"scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest",
    "flow": "node_modules/.bin/flow",
    "start-iphone6": "react-native run-ios --simulator \"iPhone 6 11.3\""
}

4）npm run start-iphone6

Answer 6

我为它开发了CLI工具。您只需输入“rndcli”并选择设备

即可

https://github.com/nazrdogan/rndcli

Answer 7

正如Ian L回答的那样，我还使用NPM来管理脚本。

示例：

{
  "scripts": {
    "ios": "react-native run-ios --simulator=\"iPad Air 2\"",
    "devices": "xcrun simctl list devices"
  }
}

这样，我可以快速获得所需的东西：

列出所有设备：npm run devices
运行默认模拟器：npm run ios

Answer 8

这是更改iOS模拟器的新途径，您只需更改

default: 'iPhone 6' or something else

路径：

<project_root>/node_modules/@react-native-community/cli/build/commands/runIOS/runIOS.js

Answer 9

使用此命令获取设备列表

xcrun simctl list devices

控制台

Answer 10

我在使用XCode 10.2指定正确的iOS模拟器版本号时遇到了问题，所以使用了：

react-native run-ios --simulator='iPhone X (com.apple.CoreSimulator.SimRuntime.iOS-12-1)'

Answer 11

更改/node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js的行代码

第55行

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
from matplotlib import cm

np.random.seed(15)
df = pd.DataFrame(columns=['X', 'Y', 'val'])
df['X'] = np.random.randint(-226,227,300)
df['Y'] = np.random.randint(-27,462,300)
df['val'] = np.random.randint(0,3000,300)/1000
fig, ax = plt.subplots(figsize=(10,10))
hexbin = ax.hexbin(df['X'], df['Y'], C=df['val'].values, reduce_C_function=np.bincount)

替换：

  if (
    simulator.availability !== '(available)' &&
    simulator.isAvailable !== true
  ) {
    continue;
  }

Answer 12

有多种方法可以实现这一目标：

使用--simulator标志
使用--udid标志

首先，您需要列出所有可用的设备。要列出所有运行的设备

xcrun simctl list device

这将给出如下输出：

这些是适用于iOS 13.0及更高版本的设备：

== Devices ==
-- iOS 13.6 --
    iPhone 8 (5C7EF61D-6080-4065-9C6C-B213634408F2) (Shutdown)

    Apple Watch Series 5 - 44mm (5922489B-5CF9-42CD-ACB0-B11FAF88562F) (Shutdown)

然后从输出中选择名称或uuid，然后根据需要进行操作。

要使用--simulator运行，请运行：

npx react-native run-ios --simulator="iPhone SE"

要使用--udid标志运行，请运行：

npx react-native run-ios --udid 90953319-BF9A-4C6E-8AB1-594394AD26CE

希望这个答案对您有所帮助。

Answer 13

这是世博会！

更新 XCode 后，我总是得到 iPhone 12 Max 模拟器，但我更喜欢 iPhone 8。所以这里是我采取的步骤：

当模拟器处于对焦状态时，转到 File -> Open Simulator 并选择您希望作为默认设置的那个。
关闭旧模拟器，关闭 localhost:19002 并使用 ctr + C 停止终端中的服务器。
运行 npm start，然后按 i。

现在它正在您打开的模拟器上运行。

快乐编码！

Answer 14

iPhone Xʀ 模拟器

    "iosxr": "react-native run-ios --simulator=\"iPhone Xʀ\"",

只需将此添加到 package.json 文件中的脚本

这里使用的字母“ʀ”与“R”是不同的Unicode

然后点击 $ yarn iosxr 在 iPhone Xʀ Simulator 上启动应用程序

Answer 15

如果要更改默认设备，而只需要运行react-native run-ios，则可以在finder中搜索关键字“ runios”，然后打开文件夹并修复index.js文件，将“ iphone X”更改为需要的设备
