Instance Property

directionalPressGestureRecognizer

The underlying gesture recognizer for directional button presses.

Declaration

var directionalPressGestureRecognizer: UIGestureRecognizer { get }

Discussion

The directionalPressGestureRecognizer is disabled by default. If you want to perform scrolling in direct response to up, down, left, and right arrow button presses, instead of scrolling indirectly in response to focus updates, enable this gesture recognizer.
