React-native: Update instructions to run app on iOS device using offline bundle

[varungupta85]

The instructions in the documentation to run the app on iOS device using an offline bundle says

Open ios/YourApp/AppDelegate.m
Uncomment the line, jsCodeLocation = [[NSBundle mainBundle] ...

Using latest version 0.30.0, such line is no longer present in the default AppDelegate.m file. Below is the excerpt from the default AppDelegate.m file

 NSURL *jsCodeLocation;

  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];

  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
                                                      moduleName:@"TestAppDelete"
                                               initialProperties:nil
                                                   launchOptions:launchOptions];

If I try to copy over the line from an old application and use that, I see that jsCodeLocation is returned as null.

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

Have these instructions changed? What are the new instructions to run the app using an offline bundle?

I have the same problem.

I need also a solution

Refer to the accepted answer for this stackoverflow question. The instructions for running the app on the device have changed but they are yet to be updated on the documentation.

[Manuel83]

The stackoverflow post is the solution. Now its working. An update of the React Native Documentation is required.

Please raise the priority. The situation is pretty bad...

The current react-native documentation reads:

1. Open ios/YourApp/AppDelegate.m
2. Uncomment the line, jsCodeLocation = [[NSBundle mainBundle] ...

That's inaccurate.

Apparently there is some hidden trick involving adding ip.txt to your XCode project:
React Native 0.29+ without dev mode in iOS?

It's also pretty unclear to me how one should integrate CodePush with RCTBundleURLProvider, see https://github.com/Microsoft/react-native-code-push/issues/393

Please update the documentation ASAP. Thx!

The docs are fixed in this PR right? https://github.com/facebook/react-native/pull/9748

See next release's docs: http://facebook.github.io/react-native/releases/next/docs/running-on-device-ios.html

@tiemevanveen I don't agree that the docs are fixed. I am still seeing that note about uncommenting the jsCodeLocation:

[teameh]

No not yet, but will be in the next release. You can already see the "next" documentation in the link I posted

[PublicParadise]

Yes, you are right. Looks better. Will ip.txt be eventually documented as well?
