服务器地址错误

运行时产生以下错误:Could not connect to development server.

1、URL地址设置

问题:

Could not connect to development server.
Ensure the following:
- Node server is running and available on the same network - run 'npm start' from react-native root
- Node server URL is correctly set in AppDelegate
URL: http://localhost:8081/index.ios.bundle?platform=ios&dev=true
2016-08-29 17:52:29.307 [error][tid:main][RCTWebSocketManager.m:84] WebSocket connection failed with error Error Domain=NSPOSIXErrorDomain Code=61 "Connection refused"

解决:

在AppDelegate.m文件中,把一下代码中的localhost改为你电脑的IP地址，并且保证连接的是同一个网络(例如:连接同一个路由的网络)。

jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];
