xcode高版本啓動RN項目常見錯誤

xcode編譯報錯：'config.h' file not found

解決方案

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

啓動報錯：Unknown argument type '__attribute__' in method -[RCTAppState getCurrentAppState:error:]. Extend RCTConvert to support this type.

個人xcode版本：Version 11.0 (11A420a)

Mac系統版本：10.14.6

緣由：Xcode11(iOS13)中對未使用的接口選擇器的參數unused字符串屬性進行了更改爲了__unused__，致使ReactNative動態收集接口時不能把聲明的接口進行導入，運行時沒法查找到該接口致使的錯誤。

解決方案：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))");
}

修改爲：

static BOOL RCTParseUnused(const char **input)
{

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