iPhone Passcode Entry Points

I've written a passcode system for my iPhone app, and currently have it working perfectly in the -applicationDidFinishLaunching method, but I was wondering what are the other methods I have to override to account for things like sleep, and multitasking?


For the app delegate, probably

- (void)applicationDidBecomeActive:(UIApplication *)application;


- (void)applicationWillEnterForeground:(UIApplication *)application;

You might also want to use:

- (void)applicationSignificantTimeChange:(UIApplication *)application;

I think that covers it, though.
