Features
The Notification Center was first seen in Android OS but has since been developed by Apple to be implemented in iOS 5. The notifications in Notification Center collate in a window which can be dragged down from the menu bar. If the user touches the notification, they will go to the application that the notification is from. There are three flavors of notifications: Banner-style messages strip across any app that are being used, including the phone's lock screen. Alerts are the familiar, large blue screens that pop up and demand action before being dismissed. The weather, phone, Messages, calendar, stock, mail, and Game Center applications are the default applications that are supported within Notification Center.[2] The Apple-designed applications Apple Store and Cards are supported as well.[3] Notification Center can also be customized to be viewed on the lock screen. A user can respond to a notification on the lock screen by swiping on it.
