Listen to what you're being told. The signal that "the home button is pressed and the home screen is presented" is NSApplication's delegate message applicationDidEnterBackground: and the corresponding NSNotification. The app is background; the view is not disappearing. *No* view controller has *ever* signaled viewWillDisappear: merely because the app is backgrounding.

(It is true that view controllers used to signal viewWillDisappear: when the app was *terminating*. But those days are long gone; we are in the iOS 4 world of multitasking now.)
