一.环境搭建ios
1.ios启动时cocoapod报错关于cdn的东西下载不下来的问题
需要在Podfile首行增加
source 'https://github.com/CocoaPods/Specs.git'
2.解决上述问题后，又出现No script URL provided. Make sure the packager is running or you have embedded a JS bundle in your a这个报错
需要讲ios下的build目录删除，打开一个窗口运行npx react-native start,再打开一个窗口运行npx react-native run-ios
