第一步、新建iOS项目（cocoapods）

第二步、在项目中建一个名为reactnative的文件夹, 用于存放我们react-native的相关文件, 再创建一个package.json文件, 用于初始化react-native的相关配置.(此处复制于另一个mobX项目)

{
  "name": "MobXTest",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "babel-plugin-syntax-decorators": "^6.13.0",
    "babel-plugin-transform-decorators-legacy": "^1.3.5",
    "babel-preset-mobx": "^1.0.3",
    "babel-preset-stage-0": "^6.24.1",
    "mobx": "^5.1.0",
    "mobx-react": "^5.2.5",
    "react": "16.4.1",
    "react-native": "0.56.0"
  },
  "devDependencies": {
    "babel-jest": "23.4.2",
    "babel-preset-react-native": "^5",
    "jest": "23.5.0",
    "react-test-renderer": "16.4.1"
  },
  "jest": {
    "preset": "react-native"
  }
}

cd reactnative
yarn install

第三步、创建一个index.ios.js，为RN界面

/** @format */

import {AppRegistry, StyleSheet, Text, View, TextInput,TouchableOpacity} from 'react-native';

import React, {Component} from 'react';

class Root extends Component {
    render() {
        return (
            <Text>iOS项目中集成RN</Text>
        );
    }
}
AppRegistry.registerComponent('iOSInstallRN', () => Root);

第四步、添加ReactNative

reactnative 为之前建立的文件夹

platform :ios, '9.0'
use_frameworks!
target 'iOSInstallRN' do
pod 'AFNetworking'
pod 'MBProgressHUD'
pod 'React', :path => './reactnative/node_modules/react-native', :subspecs => [
  'Core',
  'DevSupport',
  'RCTText',
  'RCTNetwork',
  'RCTWebSocket',
  'RCTImage',
  'RCTGeolocation',
  'RCTSettings'
  ]
pod 'yoga', :path => './reactnative/node_modules/react-native/ReactCommon/yoga'
end

pod install

第五步、配置App Transport Security

  <key>NSAppTransportSecurity</key>
  <dict>
    <key>NSExceptionDomains</key>
    <dict>
      <key>localhost</key>
      <dict>
       <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
       <true/>
      </dict>
    </dict>
  </dict>

❌这种问题可能是ios支持的版本太低，建议升高，此处改为9.0

❌RCTRootView.h file not found

在Header Search Paths 添加 $(SRCROOT)/../node_modules/react-native/React

❌(暂未遇到)
在Other Linker Flags中添加-lc++即可。
注：-lc++要添加在JavaScriptCore之后，否则编译也不过。

❌如果是版本0.45=<x<=0.46，则需要增加RCTBatchedBridge，cocoapods中增加BatchedBridge，如果版本>0.46则需要用RCTCxxBridge，增加DoubleConversion, Folly,Glog。

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

修改Podfile

platform :ios, '9.0'
use_frameworks!
target 'iOSInstallRN' do
pod 'AFNetworking'
pod 'MBProgressHUD'
pod 'React', :path => './reactnative/node_modules/react-native', :subspecs => [
  'Core',
  'DevSupport',
  'RCTText',
  'RCTNetwork',
  'RCTWebSocket',
  'RCTImage',
  'RCTGeolocation',
  'RCTSettings',
  'CxxBridge' # Include if RN >= 0.47
  ]
pod 'yoga', :path => './reactnative/node_modules/react-native/ReactCommon/yoga'
pod 'DoubleConversion', :podspec => './reactnative/node_modules/react-native/third-party-podspecs/DoubleConversion.podspec'
pod 'Folly', :podspec => './reactnative/node_modules/react-native/third-party-podspecs/Folly.podspec'
pod 'glog', :podspec => './reactnative/node_modules/react-native/third-party-podspecs/glog.podspec'

end

1、如果可以翻墙 直接pod install
2、(我采用此方法)如果不能, 新建third-party文件,在百度云上面下载这四个文件解压，将4个文件放入third-party中

❌
#import <React/RCTRootView.h>

❌
