javascript - React Native IOS 生产版本 : RCTFatalException crash and SocketProtocolError YellowBox

Question

我有一个 react-native 应用程序(目前仅适用于 iOS)——并且来自 JS 背景并且不熟悉 XCode，我发现有关为 iOS 创建生产构建的文档非常稀少。根据 https://facebook.github.io/react-native/docs/running-on-device-ios.html 上的一个模糊句子:
The JS bundle will be built for dev or prod depending on your app's scheme (Debug = development build with warnings, Release = minified prod build with perf optimizations). To change the scheme navigate to Product > Scheme > Edit Scheme... in xcode and change Build Configuration between Debug and Release.

但是，在 XCode v7.3 中，当我单击“产品”>“方案”>“编辑方案”时看到的内容(没有“在调试和发布之间更改构建配置”的选项):



我了解如何在本地手机上运行，​​以及在模拟器上运行与手机上运行的区别。它在模拟器和插入的手机上运行良好。

现在，当我归档应用程序、保存以进行临时分发、上传到 TestFairy、在手机上下载并运行它时 - 我经常看到类似 Yellowbox 警告的内容:



还有像这样的可疑崩溃(由TestFairy记录):

Application Specific Information:
*** Terminating app due to uncaught exception 'RCTFatalException: 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://192.168.0.21:8081/index.ios.bundle?platform=ios', reason: 'Could not connect to development server.

Ensure the following:
- Node serv...'

那么，在 XCode 中创建用于分发的 react native 生产构建的正确步骤是什么？

更新

我找到了这个问题的赞成答案 How to build .IPA for React Native?至解决问题 .由于该帖子上的问题与我的问题无关，因此我将保留它，但它通过使用命令行解决了创建生产构建的问题:
react-native bundle --dev false --entry-file index.ios.js --bundle-output ios/main.jsbundle --platform ios

并且在 AppDelegate.m 中取消注释这一行:
jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
