If you have an iPhone, there’s a good chance that you’ve received notifications for events that happened before your current iOS device was released. If so, you can view and manage these notifications using the Notification Center on your device. To open the Notification Center on your iPhone, open the Settings app and select “Notification Center.” In the Notification Center, you’ll see a list of all of your recent notifications. You can see which events were sent to you by default and which ones you’ve added yourself by clicking on one of the icons in the list. You can also manage these notifications by selecting one of three options: Show All Notifications, Hide All Notifications, or Remove All Notifications from This Device. If you select Show All Notifications, all of your recent notifications will be displayed in the Notification Center. If you hide all notifications or remove them from this device, only those that were sent to you will be displayed.
