1.先在項目工程中根目錄新建一個ReactNative文件夾，在此文件夾中中新建一個package.json文件，在文件中寫入

 {
          "name": "ReactNativeDemo",
           "version": "0.0.1",
           "private": true,
          "scripts": {
           "start": "node node_modules/react-native/local-cli/cli.js start"
                          },
              "dependencies": {
                               "react": "16.6.3",
                               "react-native": "^0.58.6"
            }
 }

3.創(chuàng)建index.js文件作為程序入口。
4.在podfile中添加第三方依賴庫

platform :ios, '10.0'
source 'https://github.com/CocoaPods/Specs.git'
react_native_path = './ReactNative/node_modules/react-native'

target 'ExchangeToken' do
  use_frameworks!
  pod 'RxSwift' #響應(yīng)式編程
  pod 'RxCocoa' #響應(yīng)式cocoa
  pod 'Moya/RxSwift' #網(wǎng)絡(luò)請求
  pod 'RxDataSources' #列表處理
  pod 'ObjectMapper' #模型
  pod 'Moya-ObjectMapper/RxSwift'
 #數(shù)據(jù)庫
  pod 'SDCAlertView'
  pod 'IQKeyboardManagerSwift' #鍵盤處理
  pod 'Toast-Swift', '~> 4.0.0' #toast
  pod 'Kingfisher'  #圖片處理
  pod 'SwiftDate' #時間處理
  pod 'PullToRefresher' #刷新
  pod 'EmptyPage'#空白頁
  pod 'SwifterSwift'
  pod 'SnapKit'
  pod 'DropDown'
  pod 'CHKLineChartKit'
# 'node_modules'目錄一般位于根目錄中
# 但是如果你的結(jié)構(gòu)不同，那你就要根據(jù)實(shí)際路徑修改下面的`:path`
pod 'React', :path => react_native_path, :subspecs => [
'Core',
#'BatchedBridge', # 0.45 版本以后需要添加
'CxxBridge',
'DevSupport', # 如果RN版本 >= 0.43，則需要加入此行才能開啟開發(fā)者菜單
'RCTText',
'RCTImage',
'RCTNetwork',
'RCTWebSocket', # 這個模塊是用于調(diào)試功能的
# 在這里繼續(xù)添加你所需要的模塊
]
# 如果你的RN版本 >= 0.42.0，則加入下面這行
pod 'yoga', :path => react_native_path + '/ReactCommon/yoga'
# Third party deps
pod 'DoubleConversion', :podspec => react_native_path + '/third-party-podspecs/DoubleConversion.podspec'
pod 'glog', :podspec => react_native_path + '/third-party-podspecs/glog.podspec'
pod 'Folly', :podspec => react_native_path + '/third-party-podspecs/Folly.podspec'



  # Pods for ExchangeToken
  target 'ExchangeTokenTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'ExchangeTokenUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

5.更新podfile文件
6.在UIViewController中調(diào)用時需要跟RN工程師進(jìn)行制定規(guī)則，我是用Swift集成調(diào)用如下：

    func setRN()  {
        let urlLocal = NSURL.init(string: "http://localhost:8081/index.bundle?platform=ios")
        let rootView = RCTRootView.init(bundleURL: urlLocal! as URL, moduleName: "App", initialProperties: ["scores":[["name" : "Alex","value":12],["name" :"Joel","value":314]]], launchOptions: [:])
           view = rootView
    }
