A notification informs a user about information received on their Apple Watch, such as a message, an upcoming appointment, or new data. These notifications appear in the form of an alert message or a badge on the app icon. Depending on the app settings, you may also hear a voice alert when you receive a notification. The iOS platform supports both local notifications and remote notifications (or push notifications.)

A local notification is scheduled by an app and delivered on the same device. Whereas, a remote notification is sent by your server to the Apple Push Notification service (APNS) and from there the notification is delivered to your device.

The notifications you receive are either short look notification or long look notifications. To customize a

  • Short-Look Notification uses a static notification.
  • Long-Look Notification you can use both static notification and dynamic notification.

The following example shows how a notification appears on your watch.

Short-Look Notification Long-Look Notification

You may receive a Short-Look notification instead of a Long-Look notification due to the following reasons:

  • Battery Saver is on.
  • You have exceed your carrier's data plan limits.
  • Data Sense is enabled and you have exceeded your specified limit.
  • Dynamic notification not configured.

A notification consist of following panes:

  • Sash: It is the top pane of a notification. In Sash, the app icon (you can upload the icon from the Project Settings > Apple Watch OS > Long-Look Notification Icon) and project title are displayed.
  • App Content: The central pane of a notification. Here, you can design a notification using the Volt MX Iris widgets.
  • Dismiss: The bottom pane of a notification. This pane contains system defined Dismiss button only. You cannot delete this button or add another widget.

Add a Static Notification

In Volt MX Iris, initially when you add a notification, it implies that you are adding a static notification. Only after you add a static notification, you can add a dynamic notification.

To add a static notification, follow these steps:

  1. Expand the Watch channel and hover on Notifications to display a drop-down arrow.
  2. Click the drop-down arrow and click New Notification. A new static notification is created. The system assigns a unique name to this notification.
  3. Rename the notification (if required) by clicking the drop-down arrow next to the notification and then clicking Rename. The notification name becomes an editable text field. Rename the notification and then press Enter on your keyboard.

Add a Dynamic Notification

You can add a dynamic notification only after you have added a static notification. For each static notification, you can add only a single dynamic notification.

To add a static notification, follow these steps:

  1. Hover on a static notification to display a drop-down arrow.
  2. Click the drop-down arrow and then click Create Dynamic Notification.

    A new dynamic notification is created with the same name as static notification and appended with the word [Dynamic]. For example, if a static notification is named watchNotification, its dynamic notification is named as watchNotification [Dynamic].

    Note: If a static notification is renamed, its dynamic notification is also renamed. The dynamic notification follows the naming convention Name of the static notification + [Dynamic].

Difference between a Static Notification and Dynamic Notification

  • A static notification displays the notification’s alert message and any static images and text are configured during design time.
  • A dynamic notification allows you to customize the appearance of your notification’s content. This notification is optional when designing a notification scene.
