Intro

A banner is a notification that appears on the screen to inform the user about a certain event or a change in system status. It contains a short notification text and optionally a button to allow the user to take a recommended action

Banner examples: an error, an offline, and a syncing banner

Usage

Use a banner when the user needs to be informed about a certain event or a change in system status. Keep the text of the notification message short and concise to avoid blocking other important content on the screen.

Do’s

Keep the text short and concise
Ensure that the user can still interact with the device

Don’ts

Don’t allow the text to be longer than 1 or 2 lines
Don’t let the banner text cover up other important information on the screen

Example of a short banner text

Behavior and Interaction

Touch Targets

The banner contains three possible touch targets: the bar, a dismiss button and an action button.

Banner Position

The banner appears by sliding down from underneath the navigation bar, or a header component, if it is present. It slides up the same way to disappear. By default, it will cover parts of the content below. The banner can also be customized to appear between the content and push it down without covering it up.

Position of the banner when appearing

Scrolling

The banner sticks to the navigation bar when the user scrolls up or down. If there is a header component between the navigation bar and the banner, the banner will stick to the navigation once the user scrolls up while the header component disappears.

The screens from the left to right show how the banner sticks to the navigation bar

Content Underneath a Banner

By default, the banner slides down without impacting the content scroll position. If the user scrolls to the top, content that is hidden underneath might show up.

Example where content is hidden underneath a banner

Adaptive Design

The banner follows the global layout margin of the iOS size classes (compact and regular) and therefore adapts to any iPhone or iPad device and its containers.

Variations

Progress Banner

A progress banner is used to indicate a loading process or an in-progress state. Users can be enabled to pause or stop the progress by tapping on the bar.

Example of a progress banner

Persistence

A banner is, by default, persistent and won’t disappear unless the system status or condition described in the banner text changes. If you want a banner to disappear after a certain time, you can set a timer or provide an option for the user to dismiss it.
