react native Unknown argument type ‘__attribute__’ in method

找到myproject/node_modules/react-native/React/Base/RCTModuleMethod.mm. 【或者（.m）】文件

修改static BOOL RCTParseUnused 方法如下：

static BOOL RCTParseUnused(const char **input)
{
return RCTReadString(input, “unused”) || RCTReadString(input, “__attribute((unused))”) ||
RCTReadString(input, “attribute((unused))”);
}

重新编译
