Remarks

iOS applications are expected to be long-lived, with many transitions between activated and non-activated states (see OnActivated(UIApplication), OnResignActivation(UIApplication)) and are typically only terminated by user command or, rarely, due to memory exhaustion (see ReceiveMemoryWarning(UIApplication)).
