Core Application Architecture •EveryiPhone app is created by using the UIKit Framework • From the time the application is launched by the user, to the time it exits, the UIKit framework manage it •the application continuouslyreceives events from the system and must respond to those events •UIApplication object is receiving those events, but responding to the events should be done in the code

Editor's Notes
- #10 The application life cycle constitutes the sequence of events that occurs between the launch and termination of your application. In iPhone OS, the user launches your application by tapping its icon on the Home screen. Shortly after the tap occurs, the system displays some transitional graphics and proceeds to launch your application by calling its main function. From this point on, the bulk of the initialization work is handed over to UIKit, which loads the application’s user interface and readies its event loop.During the event loop, UIKit coordinates the delivery of events to your custom objects and responds to commands issued by your application. When the user performs an action that would cause your application to quit, UIKit notifies your application and begins the termination process.
