When the view controller’s
modal property is
UIModal, UIKit uses the object in this property to facilitate transitions and presentations for the view controller. The transitioning delegate object is a custom object that you provide and that conforms to the
UIView protocol. Its job is to vend the animator objects used to animate this view controller’s view onscreen and an optional presentation controller to provide any additional chrome and animations.
