 2. ##### Deep Linking

 	* Handling Links from Push Notifications
 		
 		Push notifications and action buttons may have `openUrl` actions attached to them. When a URL is specified, the SDK first calls `urlDelegate` specified in your `IterableConfig` object. You can use this delegate to handle `openUrl` actions the same way as you handle normal deep links. If the delegate is not set or if it returns `false` (the default), the SDK will open Safari with that URL. If you want to navigate to a UIViewController on receiving a deep link, you should do so in the `urlDelegate`.
