React Native iOS 之Could not connect to development server.
React Native 是目前最火的开发框架,其他不说了,上Bug。
按照 React Native iOS环境搭建 高级版
在mac上 搭建 React Native 环境,运行 项目 若出现了如下情况。
模拟器上 显示
Xcode 打印
2016-02-16 17:01:49.806 [info][tid:com.facebook.React.JavaScript][RCTJSCProfiler.m:63] JSC profiler is not supported.
2016-02-16 17:01:50.089 [fatal][tid:main] 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
请将项目中 AppDelegate.m 中的
jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];
替换为
jsCodeLocation = [NSURL URLWithString:@"http://127.0.0.1:8081/index.ios.bundle?platform=ios&dev=true"];
原因之一:做本地局域网开发环境,大部分都会做服务器映射处理,localhost 被指向特定的IP 而不是本机的127.0.0.1, 就会出现这样的问题。
