# interactionControllerForPresentation(using:)

Asks your delegate for the interactive animator object to use when presenting a view controller.

## Declaration

```swift
optional func interactionControllerForPresentation(using animator: any UIViewControllerAnimatedTransitioning) -> (any UIViewControllerInteractiveTransitioning)?
```

## Parameters

- `animator`: The transition animator object returned by your doc://com.apple.uikit/documentation/UIKit/UIViewControllerTransitioningDelegate/animationController(forPresented:presenting:source:) method.

## Return Value

Return Value The interactive animator object to use to manage the timing of the transition or nil if you do not want to support interactive transitions.

## Discussion

Discussion Use this method to create and return an object that implements the methods of the UIViewControllerInteractiveTransitioning protocol. The implementation of that protocol should configure the event-handling code required to manage the appearance of the target view controller. You may return nil from this method if you do not want to the animations to be interactive. important: If you implement this method, you must also implement the animationController(forPresented:presenting:source:) method and use it to return a custom transition animator object. If the animationController(forPresented:presenting:source:) method returns nil, UIKit does not call this method. For more information on implementing an interactive animator object, see UIViewControllerInteractiveTransitioning.
