Controller object UIApplication is used without subclassing to manage the application event loop. It coordinates other high-level app behaviors.
Some of the behaviours of UIApplications:
-It works along with the app delegate object which contains app-level logic.
-Control the app’s response to changes in interface orientation.
-Register for remote notifications.
-Extend the execution of the app so that it can finish a task in the background.
-Schedule and cancel local notifications.
-Coordinate the reception of remote-control events.
(A major role of a UIApplication object is to handle the initial routing of incoming user events. It also dispatches action messages forwarded to it by control objects (UIControl) to the appropriate target objects.)
