UI Deploy

Way back in iOS 3.0, Apple introduced the Push Notification Service (APNS) to bring the multitasking support to its mobile operating system. At that time, due to the nature of iOS, only one application is allowed to run in the foreground. Push notification changes the game by allowing applications to receive updates even it’s not actively running. When a notification comes in, iOS displays the notification in the form of on-screen alerts or sounds and it’s up to the user to decide whether to launch the application.
