title: NSLocalNotification - show notification animation when the app is running in iOS5
body: <p>Is it possible to show <code>NSLocalNotification</code> when the app is running and in the foremost position? As the <code>Apple document</code> says when the app is in the foremost position the notification will not be shown (it shows in notification center though, just doesn't have the flipping animation on top), then what's the point for method <code>presentLocalNotificationNow</code>: ?</p>
