# NSViewControllerPresentationAnimator

A set of methods that let you define animations to play when transitioning between two view controllers.

## Declaration

```swift
protocol NSViewControllerPresentationAnimator : NSObjectProtocol
```

## Overview

Overview Implement this protocol only if you want to provide custom animations. You might find what you need in the NSViewController.TransitionOptions enumeration, which provides many predefined animations. A class that adopts this protocol is responsible for both presenting and dismissing a view controller.
