RN0.52版本后，开启remote debug后， chrome会显示报错，类似
Failed to load http://192.168.0.105:8081/index.delta?platform=ios&dev=true&minify=false: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8081' is therefore not allowed access. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
或者

，程序不能正常运行！
解决方法是，安装chrome插件“Allow-Control-Allow-Origin”，之后就正常了，吼吼！
