ios - How to use url stored in Appdelegate.m inside JavaScript -

i'm working on ios hybrid app cordova , backbone.js. stored url in appdelegate.m file using nsuserdefaults. want import url in backbone.js file instead of hard coded url in file.

here's sample code that.

native code used in appdelegate.m

nsuserdefaults *defaults = [nsuserdefaults standarduserdefaults];  // initial launch url console app policy nsdictionary *apppolicydictionary =[gdlibrary getapplicationpolicy]; nsstring *serviceurlfrompolicy =[[apppolicydictionary objectforkey:@"loginurl"]objectforkey:@"loginurl"]; [defaults setobject:serviceurlfrompolicy forkey:@"loginurl"]; [defaults synchronize]; 

how declared url in backbone.js

define(["jquery", "backbone"], function($, backbone) {       var appconfig = {         defaults: {             env: "dev"         },          session_timeout: 30 * 60, // in seconds          dev: {             url: 'https://www.myurl.com'         }     }
