NSInternalInconsistencyException:未实现loadSourceForBridge时,bundleURL必须为非nil

Question

我最近开始在我使用的iOS移动应用程序中得到此错误(下面的详细错误)react-native.这种情况只有在我尝试通过使用Option 2静态捆绑加载手机上的应用程序时才会发生.我试过了:

• 在Xcode中清理和重建
• 重置缓存并运行react packager
• 在手机上卸载应用程序
• 来自Windows背景,我也试图重启我的机器

Xcode出错

我可以看到这个问题是印刷在这里的代码,但我在原生iOS开发充其量是一个初学者,不知道如何解决这个问题.

请帮我解决这个问题.谢谢!

AppDelegate.swift文件中的代码

/**
 * Loading JavaScript code - uncomment the one you want.
 *
 * OPTION 1
 * Load from development server. Start the server from the repository root:
 *
 * $ npm start
 *
 * To run on device, change `localhost` to the IP address of your computer
 * (you can get this by typing `ifconfig` into the terminal and selecting the
 * `inet` value under `en0:`) and make sure your computer and iOS device are
 * on the same Wi-Fi network.
 */
// let jsCodeLocation = NSURL(string: "http://localhost:8081/index.ios.bundle?platform=ios&dev=true")


 /**
 * OPTION 2
 * Load from pre-bundled file on disk. The static bundle is automatically
 * generated by "Bundle React Native code and images" build step.
 */
let jsCodeLocation = NSBundle.mainBundle().URLForResource("main", withExtension: "jsbundle")

正如您所看到的,我已经注释掉Option 1并取消注释了"选项2".我在设备上以这种方式运行相同的应用程序,如100次.我没有对代码进行任何更改,但突然间我开始看到上面的错误.

如果您没有正确签署应用程序，您也可能会收到此错误。检查 Xcode 设置和警告
