# scrollViewDidEndDecelerating(_:)

Tells the delegate that the scroll view ended decelerating the scrolling movement.

```
optional func scrollViewDidEndDecelerating(_ scrollView: UIScrollView)
```

## Parameters

`scrollView`

The scroll-view object that’s decelerating the scrolling of the content view.

## Discussion

The scroll view calls this method when the scrolling movement comes to a halt. The [`isDecelerating`](/documentation/UIKit/UIScrollView/isDecelerating) property of `UIScrollView` controls deceleration.
