pageScrolled
A notification that an app posts when a scroll action completes.
Declaration
nonisolated static let pageScrolled: UIAccessibility.NotificationDiscussion
This notification includes a parameter that is an 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 accessibilityScroll(_:) method using the post(notification:argument:) function.
