I'm sure this is a newbie question. I have most of my code in my main view controller. Works fine. I'd like to be told when the app is launching, or when the iPhone is going to sleep. I can add this: - (void)applicationWillTerminateUIApplication *)application to my AppDelegate class, and that's fine. But my AppDelegate doesn't know the objects I want to deal with at shutdown. But I'd like to add it to my view controller class. If I type it in, it says it doesn't know what applicationWillTerminate means. Alternatively, I can catch it in the AppDelegate class, then call a instance method in my ViewController class. But I don't know how to do that either. So, some newbie help would be appreciated! Thank you!
