Notes

React Native iOS 打包

工程根目录下执行 js 文件打包命令

react-native bundle --entry-file demo/index.js --bundle-output ./ios/bundle/index.ios.jsbundle --platform ios --assets-dest ./ios/bundle --dev false

首先要确保相应的文件夹已经存在,如 📁bundle

–entry-file JS 文件的总入口 绝对路径 相对路径

–bundle-output JS 打包文件的出口

–platform 平台 ios 或者 android

–assets-dest JS 打包文件中,存放资源文件的路径,精确到文件夹名称

–dev 若为 false,JS 打包文件将会被压缩,同时 warning 会停用


最后生成在 ios 目录下,生成 📁assets 和 📃index.ios.jsbundle,可能还会有 📃index.ios.jsbundle.meta,但这个不需要

添加 JS 打包文件到 iOS 项目下

将 📁assets 和 📃index.ios.jsbundle 添加到项目文件夹下,其中 📁 通过 Create folder references 的方式添加,即添加完成后,图标为蓝色文件夹的那种

修改原生代码中,js 入口文件的读取路径

修改 AppDelegate.m 为

jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"index.ios" withExtension:@"jsbundle"];
