If you are bothered by push notifications coming to your lock screen or the Notifications panel of iOS, you can stop them easily. Many apps will try to send you notifications even App Store too. If those bother you and you don’t wan to clear them, the best thing is to disable their ability to post a notification to your iDevice.
This change take effect immediately. After this change, you will get zero alerts, banners or notifications for those apps.
You can change your decision later. If you want to get notification again you can reverse it back.
