Push notifications are not working in updated vers

I updated my device from ios7 to ios8.1.Push notifications are not working in updated version. I did same process for push notifications which is done in ios7. The code is also updated

    #ifdef __IPHONE_8_0
      //Right, that is the point
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge
    |UIUserNotificationTypeSound
    |UIUserNotificationTypeAlert) categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
#else
    //register to receive notifications
    UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];
#endif

By using the above code also i didnot get notification.Please help me for push notifications in ios8.1.

thanks inadvance

The method for receiving a push notification has also changed:

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier

See Handling Local and Remote Notifications and UIApplicationDelegate for more info.

Here is a full example of an application delegate:

- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
        NSLog(@"Requesting permission for push notifications..."); // iOS 8
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:
            UIUserNotificationTypeAlert | UIUserNotificationTypeBadge |
            UIUserNotificationTypeSound categories:nil];
        [UIApplication.sharedApplication registerUserNotificationSettings:settings];
    } else {
        NSLog(@"Registering device for push notifications..."); // iOS 7 and earlier
        [UIApplication.sharedApplication registerForRemoteNotificationTypes:
            UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge |
            UIRemoteNotificationTypeSound];
    }
    return YES;
}

- (void)application:(UIApplication *)application
    didRegisterUserNotificationSettings:(UIUserNotificationSettings *)settings
{
    NSLog(@"Registering device for push notifications..."); // iOS 8
    [application registerForRemoteNotifications];
}

- (void)application:(UIApplication *)application
    didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)token
{
    NSLog(@"Registration successful, bundle identifier: %@, device token: %@",
        [NSBundle.mainBundle bundleIdentifier], token);
}

- (void)application:(UIApplication *)application
    didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
    NSLog(@"Failed to register: %@", error);
}

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier
    forRemoteNotification:(NSDictionary *)notification completionHandler:(void(^)())completionHandler
{
    NSLog(@"Received push notification: %@, identifier: %@", notification, identifier); // iOS 8
    completionHandler();
}

- (void)application:(UIApplication *)application
    didReceiveRemoteNotification:(NSDictionary *)notification
{
    NSLog(@"Received push notification: %@", notification); // iOS 7 and earlier
}
