PercentDrivenInteractionController

public protocol PercentDrivenInteractionController : UIViewControllerInteractiveTransitioning

PercentDrivenInteractionController is used for interaction controller types that can updated based on a percentage of completion. Furthermore, a PercentDrivenInteractionController should be able to cancel and finish a transition animation.

PercentDrivenInteractionController is based on the UIViewControllerInteractiveTransitioning protocol.

Note

While you can implement your custom implementation, UIKit offers a default implementation with UIPercentDrivenInteractiveTransition.
