两种生成jsbundle方式：

• curl命令download jsbundle
• react-native bundle 命令生成

curl命令生成

1.在React Native项目根目录下运行 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中选择使用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]

打包步骤：

1. 工程目录下执行
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文件夹

3. 在AppDelegate.m中选择使用main.jsbundle
jsCodeLocation = [[NSBundle mainBundle] URLForResource:@”index.ios” withExtension:@”jsbundle”];
