# UIDynamicAnimatorDelegate

To respond to the pausing or resumption of UIKit dynamic animation, configure a custom class to adopt the UIDynamicAnimatorDelegate protocol. Then, in a dynamic animator (an instance of the UIDynamicAnimator class), set the delegate to be an instance of your custom class.

## Declaration

```swift
@MainActor protocol UIDynamicAnimatorDelegate : NSObjectProtocol
```
