When trying to build ios client in react-native, I modified part of AppDelegate.m file as shown below (i.e., replaced option 1 with option 2):
// 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, and make sure your computer and
// iOS device are on the same Wi-Fi network.
//jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle"];
// OPTION 2
// Load from pre-bundled file on disk. To re-generate the static bundle, run
//
// $ curl http://localhost:8081/index.ios.bundle -o main.jsbundle
//
// and uncomment the next following line
jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
I downloaded main.jsbundle to the iOS folder where AppDelegate.m is.
$ ls iOS
AppDelegate.h Base.lproj Info.plist main.m
AppDelegate.m Images.xcassets main.jsbundle
But, if I do the build again in XCode and run it in ios simulator, it pauses in main.m with the following error:
2015-03-31 12:46:28.877 AwesomeProject[26849:1320518] * Assertion failure in -[RCTRootView initWithBundleURL:moduleName:launchOptions:], /Users/yourname/scripts/code/startup/reactnative/AwesomeProject/node_modules/react-native/React/Base/RCTRootView.m:82 2015-03-31 12:46:28.883 AwesomeProject[26849:1320518] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'A bundleURL is required to create an RCTRootView'
So, it seems to be complaining about bundleURL. I will appreciate help with identifying what the issue is.
You need to add the file to the project. To do so, you need to right-click on the project name and select "Add files to MyProject…". Then choose the main.jsbundle.
Then build your project and it should work.
