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

Question

我有一个react-native应用程序(目前仅限iOS) - 来自JS背景并且不熟悉XCode，我发现有关为iOS创建生产版本的文档非常稀疏。根据https://facebook.github.io/react-native/docs/running-on-device-ios.html上的一个模糊的句子:

JS 包将根据您的应用程序方案为开发或生产构建(调试 = 带警告的开发构建，发布 = 带性能优化的缩小生产构建)。要更改方案，请导航到 xcode 中的“产品”>“方案”>“编辑方案...”，并在“调试”和“发布”之间更改“构建配置”。

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

我了解了如何在手机上本地运行，以及在模拟器上运行与在手机上运行的区别。它在模拟器和插入的手机上运行良好。

现在，当我存档应用程序、保存为临时分发、上传到 TestFairy、在手机上下载并运行它时 - 我经常看到诸如 Yellowbox 警告之类的内容:

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，创建用于在 XCode 中分发的 React Native 生产版本的正确步骤是什么？

更新

我找到了这个问题的赞成答案How to build .IPA for React Native? 解决问题。我将保留此问题，因为该帖子中的问题与我的问题无关，但它解决了使用命令行创建生产构建的问题:

react-native 包 --dev false --entry-file index.ios.js --bundle-output ios/main.jsbundle --platform ios

并取消 AppDelegate.m 中这一行的注释:

jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main"withExtension:@"jsbundle"];
