    What is the use of controller object UIApplication?

    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.)
