如何在iOS中重新注册推送通知

Question

I have problem in app version updates

[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications];

In my older version app I have called above method two times wrongly in didfinishedlaunch method, For that I have received the same notification twice. So I have called that method one time only. After that I have uploaded that new version into the app store.

My problem is When a user is newly installed my new version app, It will be good, I have received notification single time.

But I have upgraded the older version to the new version, The above problem is repeated for me.Same Notification shows twice.

I think you can delete the app and then reinstall it fresh and I think it will ask you about notifications again, of which will be your new code. If not then I guess it depends on your push notification service (eg Parse etc) where there maybe functionality to then delete a device from the list of registered devices for notifications etc.
