- Not Running: The app has not been launched yet or has been terminated by the system.
- Inactive: The app is running in the foreground but is not receiving user events (e.g., during an incoming call or SMS).
- Active: The app is running in the foreground and actively interacting with the user.
- Background: The app is in the background but may continue to execute code (e.g., for data loading or background tasks).
- Suspended: The app is in the background and has been suspended by the system to free resources. Code in this state is not executed.
Transitions between states are managed by the system and the AppDelegate delegate. Key delegate methods:
application:didFinishLaunchingWithOptions:: The app has successfully launched.applicationWillResignActive:: Transition from Active to Inactive.applicationDidEnterBackground:: Transition from Inactive to Background.applicationWillEnterForeground:: Transition from Background to Inactive.applicationDidBecomeActive:: Transition from Inactive to Active.applicationWillTerminate:: The app is about to terminate.
