This application demonstrates a custom presentation that coordinates between multiple animations using UIViewPropertyAnimator and view controller transition APIs.
The idea of coordinating multiple animations was explained in the Advance Animation with UIKit WWDC 2017 session 230. This application is implemented by referring to that approach.
- Manages the presentation style
- Adds custom views for presentation
- Inherits from
UIPresentationController - Conforms to the
UIViewControllerTransitioningDelegateprotocol
- Is responsible for creating the animations
- Conforms to the
UIViewControllerAnimatedTransitioningprotocol
- Drives the timing of custom animations using gesture recognizers
- Inherits from
UIPercentDrivenInteractiveTransition - Conforms to the
UIViewControllerInteractiveTransitioningprotocol
All transition animations are defined with transitionAnimators method of PresentationAnimatedTransitioning protocol.
You can refer to the implementation of SecondViewController.
