The knowledge that user experience designer must master: The notice content of design specification

Article Description: Design message notifications for iOS5.

As one of the major updates to the IOS5, the Notification Center can place all the alerts in a user's iOS device in one location, greatly facilitating user viewing and management. If a user receives a new e-mail message, a text message, or a request to add a friend, whether under any interface (including a full screen application, such as games), users can "pull down" from the top of the screen, and the notification center will be "pulled down", where the user can view all notices. So Apple's introduction to iOS5 says the notification Center is the perfect way to keep abreast of the latest life information.

Scenarios in which notifications may occur

Typically in the following scenario, the iOS application notifies the user that something interesting has happened:

1. Received a message

2. Something is about to happen

3. New data available for download

4. The State of certain things has changed

Four types of notification for IOS5

1. Banner (Banner)

A banner notification is a new feature that appears in IOS5, a bar that is displayed at the top of the screen and automatically disappears after a few seconds. A banner notice will display the program's small icon (low split screen display 29x29 icon, high split screen display 58x58 icon), program name and notification content. Small icons help users to see at a glance which application is reminding them.

2. Reminder (Alert)

Reminder notifications do not automatically disappear and require the user to interact with them to close. The designer needs to design the details of the notice, and sometimes the action button (which is discussed later) to design title. The background style of the entire reminder, including the buttons inside the style, is immutable, so designers and developers should not be creative here. Android because of its openness, we can use our own designed controls, and iOS may be doing this to keep the UI style consistent.

3. Mark (Badge)

A tag notification is a red oval mark displayed in the upper-right corner of the program's icon that shows the number of notifications that are required to be processed by the user. Similarly, the color and shape and size of the tag cannot be changed. The number of updated applications in the App Store, and the number of unread messages received in mail is notified to the user with a tag.

4. Sound (Sound)

Voice prompts are also a way of notifying iOS, which supports customization and can be used in combination with the previous three types of notifications.

Local notifications and push notifications

The iOS application uses local notifications or push notifications to alert users:

1. Local notification

Local notifications for applications are generated and published by the user's iOS device, regardless of whether the application is running in the foreground. Just like a calendar application, or a to-do list application, you can send a local alert alerting the user that a meeting is about to begin.

2. Push notification

The application's push notification is published in this way: The application's remote server (Provider) first sends a notification to Apple's push notification service (Apple push Notification service, APNs), Apple's notification server then pushes the notice to all iOS devices that have the app installed.

If you want to use push notifications, you must first register with Apple's push notification service which types of notifications you want to use, such as the following code that represents both the registration of both the tag and the sound of the two types of notifications:

-(void) applicationdidfinishlaunching: (UIApplication *) App {
