# copiesOnScroll

A Boolean value that indicates if the clip view copies rendered images while scrolling.

```
var copiesOnScroll: Bool { get set }
```

## Discussion

When the value of this property is <doc://com.apple.documentation/documentation/Swift/true>, the clip view copies its existing rendered image while scrolling (only drawing exposed portions of its document view); when it is <doc://com.apple.documentation/documentation/Swift/false>, the view forces its contents to be redrawn each time.
