Usage
Refer to the example project for details.
import ZoomTransitioning
Adopt ZoomTransitionSourceDelegate to source view controller
extension ImageListViewController: ZoomTransitionSourceDelegate { func transitionSourceImageView() -> UIImageView { return selectedImageView } func transitionSourceImageViewFrame(forward forward: Bool) -> CGRect { return selectedImageView.convertRect(selectedImageView.bounds, toView: view) } func transitionSourceWillBegin() { selectedImageView.hidden = true } func transitionSourceDidEnd() { selectedImageView.hidden = false } func transitionSourceDidCancel() { selectedImageView.hidden = false } }
Adopt ZoomTransitionDestinationDelegate to destination view controller
extension ImageDetailViewController: ZoomTransitionDestinationDelegate { func transitionDestinationImageViewFrame(forward forward: Bool) -> CGRect { if forward { let x: CGFloat = 0.0 let y = topLayoutGuide.length let width = view.frame.width let height = width * 2.0 / 3.0 return CGRect(x: x, y: y, width: width, height: height) } else { return largeImageView.convertRect(largeImageView.bounds, toView: view) } } func transitionDestinationWillBegin() { largeImageView.hidden = true } func transitionDestinationDidEnd(transitioningImageView imageView: UIImageView) { largeImageView.hidden = false largeImageView.image = imageView.image } func transitionDestinationDidCancel() { largeImageView.hidden = false } }
set delegate property of UINavigationController
import ZoomTransitioning class NavigationController: UINavigationController { private let zoomNavigationControllerDelegate = ZoomNavigationControllerDelegate() required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) delegate = zoomNavigationControllerDelegate } }
