I did everything in this tutorial:
http://www.raywenderlich.com/3443/apple-push-notification-services-tutorial-part-12
I created certificates, app_id and a Provisioning profile and try to use Push Notification Service with simple code below in delegate file:
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
// Let the device know we want to receive push notifications
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
I tried my app on my iPad but it doesn't work. iOS doesn't ask me if I allow my app to use Push Notifications, also doesn't show my app in Settings>Notifications list. I don't get an error while compiling or running my app..

Error
I just implemented "didFailToRegisterForRemoteNotificationsWithError" method and I am getting this error while running application
