# pageScrolled

A notification that an app posts when a scroll action completes.

```
nonisolated static let pageScrolled: UIAccessibility.Notification
```

## Discussion

This notification includes a parameter that is an <doc://com.apple.documentation/documentation/Foundation/NSString> object that contains a description of the new scroll position. An assistive app outputs the description string in the parameter.

Use this notification to provide custom information about the contents of the screen after a user performs a VoiceOver scroll gesture. For example, a tab-based app might provide a string like `Tab 3 of 5`, or an app that displays information in pages might provide a string like `Page 19 of 27`.

When an assistive app repeatedly receives the same scroll position string, it indicates to users that scrolling can’t continue due to a border or boundary.

Post this notification after the <doc://com.apple.documentation/documentation/ObjectiveC/NSObject-swift.class/accessibilityScroll(_:)> method using the [`post(notification:argument:)`](/documentation/UIKit/UIAccessibility/post(notification:argument:)) function.
