# allowedScrollTypesMask

A scroll type mask that enables recognition of scroll events.

## Declaration

```swift
var allowedScrollTypesMask: UIScrollTypeMask { get set }
```

## Discussion

Discussion Setting this mask enables the pan gesture to recognize scroll events, like a mouse scroll movement or a two-finger scroll on a track pad. See UIScrollType. note: Setting this property doesn’t disable scrolling through touches. To disable touch scrolling, return false from gestureRecognizer(_:shouldReceive:) or set the allowedTouchTypes to an empty array.
