No, you will receive a the notification in the appdelegate.

    //Place your code to handle the notification here.

I made an lib to make an animation almost as same as local notification's.

Check this: https://github.com/OpenFibers/OTNotification

Demo: enter image description here

enter image description here

And you can post a new message to this lib when you received a message in

- (void) application:(UIApplication *)application didReceiveLocalNotification:    (UILocalNotification *)notification
{
    OTNotificationManager *notificationManager = [OTNotificationManager defaultManager];
    OTNotificationMessage *notificationMessage = [[OTNotificationMessage alloc] init];
    notificationMessage.title = [self notificationTitle];
    notificationMessage.message = @"A notification. Touch me to hide me.";
    [notificationManager postNotificationMessage:notificationMessage];
}
