Overview

ZoomTransitioning provides a custom transition with image zooming animation. When you use this library with UINavigationController, you can pop view controller with edge swiping.

Demo

Run the demo project in the Demo directory without carthage update or pod install.

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
    }
}
