Running react-native app on iOS device using offline bundle

Question

The official React Native documentation to run app on iOS device using offline bundle says

Open ios/YourApp/AppDelegate.m

Uncomment the line, jsCo

Answer 1

When I open the global proxy in ShadowsocksX, automatic IP detection won't return http://localhost:8081/index.ios.bundle in the debug mode. That's why the URL for main.jsbundle returned as null.

How to solve?

Option 1:

replace

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

with

jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];

This method could disable automatic IP detection.

Option 2:

Switch your proxy mode if you open the global proxy mode.
