You will need to change the ip address in AppDelegate.m from localhost to your private ip.

Example:

From:
jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle"];

To:
jsCodeLocation = [NSURL URLWithString:@"http://192.168.1.10:8081/index.ios.bundle"];

@nav i know that, and it works, by changing the IP
but the problem i am facing with, occurs after i unplug the phone from computer

See #240.

If there's a way of doing this with a compile-time flag, that would be much neater.

@glenjamin , you can have a User Defined build setting in xcode, and use this flag to choose between http url or file location.

Closing in favor of #240
