兩種生成jsbundle方式：
- curl命令download jsbundle
- react-native bundle 命令生成
curl命令生成
1.在React Native項目根目錄下運行 npm start
2.使用curl命令生成 main.jsbundle
curl http://localhost:8081/index.ios.bundle -o main.jsbundle
3.在AppDelegate.m中選擇使用main.jsbundle
jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
react-native bundle 命令
react-native bundle 命令:
Options:
–entry-file Path to the root JS file, either absolute or relative to JS root [required]
–platform Either “iOS” or “android”
–transformer Specify a custom transformer to be used (absolute path) [default: “/Users/babytree-mbp13/projects/xcodeProjects/AwesomeProject/node_modules/react-native/packager/transformer.js”]
–dev If false, warnings are disabled and the bundle is minified [default: true]
–prepack If true, the output bundle will use the Prepack format. [default: false]
–bridge-config File name of a a JSON export of __fbBatchedBridgeConfig. Used by Prepack. Ex. ./bridgeconfig.json
–bundle-output File name where to store the resulting bundle, ex. /tmp/groups.bundle [required]
–bundle-encoding Encoding the bundle should be written in (https://nodejs.org/api/buffer.html#buffer_buffer). [default: “utf8”]
–sourcemap-output File name where to store the sourcemap file for resulting bundle, ex. /tmp/groups.map
–assets-dest Directory name where to store assets referenced in the bundle
–verbose Enables logging [default: false]
打包步驟：
1. 工程目錄下執(zhí)行
react-native bundle --entry-file index.ios.js --bundle-output ./bundle/iosBundle/index.ios.jsbundle --platform ios --assets-dest ./bundle/iosBundle/ --dev flase
2. 在xcode中添加bundle文件夾
3. 在AppDelegate.m中選擇使用main.jsbundle
jsCodeLocation = [[NSBundle mainBundle] URLForResource:@”index.ios” withExtension:@”jsbundle”];
