One reason of this type of behavior can be that you have not registered your application for RemoteNotifications. To register it for apns you will need to write following code in your Application Delegate’s didFinishLaunchingWithOptions method.

[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeBadge ];

It will register your device for Badge and Alert kind of notification. To verify whether application is registered or not you can go in settings>notification>your application if its their with these two kind of notification types then your application will be ready to call the delegate method and receive notification(if the switch in settings is on).

Moreover, it would be helpful if you implement application:didFailToRegisterForRemoteNotificationsWithError: method and log errors if any.
