Accelerated Scrolling support in UIKit and TVMLKit apps

Scroll views on tvOS support accelerated scrolling when a scroll view includes a large amount of content. Accelerated scrolling is activated by continuously swiping the touch surface of the remote, or by resting a finger on the right side of the touch surface of the remote. When accelerated scrolling is enabled, scrolling is faster and an index is displayed. The user can jump between index sections by swiping the right side of the touch surface. Accelerated scrolling is always enabled on all scroll views.

Your app can customize the behavior of scroll views, table views, and collection views:

• By default, a scroll view displays the index bar during accelerated scrolling. You can disable the index bar using the scroll view’s indexDisplayMode property.

• To provide section index titles for a UITableView object, implement the sectionIndexTitlesForTableView: and tableView:sectionForSectionIndexTitle:atIndex: methods on your table’s data source.

• To provide section index titles for a UICollectionView object, implement the indexTitlesForCollectionView: method on your collection view’s data source.
