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.

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

Don't

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.

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 covers parts of the content below. The banner can also be customized to appear between the content and push it down without covering it up.

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 sticks to the navigation once the user scrolls up while the header component disappears.

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.

Information

It is also technically feasible to have multiple banners. In this scenario, the second (more recent) banner would be positioned above the first one, overlaying the content of the page. However, users are still be able to access the underlying content by scrolling downwards.

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.

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.
