Asks the delegate for a region as the pointer moves within the interaction’s view.

```

## Parameters

`interaction`

This [`UIPointerInteraction`](/documentation/UIKit/UIPointerInteraction).

`request`

The [`UIPointerRegionRequest`](/documentation/UIKit/UIPointerRegionRequest) that describes the pointer’s location in the interaction’s view.

`defaultRegion`

The [`UIPointerRegion`](/documentation/UIKit/UIPointerRegion) that represents the entire surface of the interaction’s view.

## Return Value

A `UIPointerRegion` in which to apply a pointer style. Return `nil` to indicate that this interaction typically doesn’t customize the pointer for the current location.
