xcode高版本启动RN项目常见错误

xcode编译报错：'config.h' file not found

解决方案

cd node_modules/react-native/third-party/glog-0.3.4
../../scripts/ios-configure-glog.sh

启动报错：Unknown argument type '__attribute__' in method -[RCTAppState getCurrentAppState:error:]. Extend RCTConvert to support this type.

个人xcode版本：Version 11.0 (11A420a)

Mac系统版本：10.14.6

缘由：Xcode11(iOS13)中对未使用的接口选择器的参数unused字符串属性进行了更改为了__unused__，致使ReactNative动态收集接口时不能把声明的接口进行导入，运行时没法查找到该接口致使的错误。

解决方案：找到文件/node_modules/react-native/React/Base/RCTModuleMethod.mm

修改方法：

static BOOL RCTParseUnused(const char **input)
{
  return RCTReadString(input, "__unused") ||
         RCTReadString(input, "__attribute__((unused))");
}

修改为：

static BOOL RCTParseUnused(const char **input)
{

  return RCTReadString(input, "attribute((unused))") ||
         RCTReadString(input, "__attribute__((__unused__))") ||
         RCTReadString(input, "__unused");
}
