我可以看到这个问题在代码中打印了here,但我最初是本机iOS开发中的初学者,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,我已经注释掉了选项1并且没有注释掉“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.
