Undefined symbol: _OBJC_CLASS_$_WXApi

[chobitsX]

• 使用版本：react-native 0.63.2 + xcode 11.6，配置环境IOS开发环境
• 问题一：react-native link react-native-wechat-lib，按文档Build Setup for iOS 配置，依旧会提示WXApi.h文件找不到，通过在 header search paths里添加 "$(SRCROOT)/../node_modules/react-native-wechat-lib/ios"可以解决
• 问题二：xcode运行项目，遇到报错：Undefined symbol: OBJC_CLASS$_WXApi

pod install了没？

pod install了没？

pod install了好几次，依旧这个问题

[chobitsX]

经过尝试，初步找到解决办法了，我上面反馈的问题一和问题二，都可以通过下面方法解决，在终端输入以下指令(项目根目录下)

cd ios
pod install
cd ..
npx react-native link
# 虽然前面按照文档执行了react-native link react-native-wechat-lib，但上面这一步依旧不能少

应该是没有添加libRCTWechat.a, 添加到Libraries下面也可以解决
