ImageTransition
ImageTransition is a library for smooth animation of images during transitions.
Something looks like below:
| e.g. UIImageView | e.g. UIImageView in UICollectionView | 
|---|---|
![]()  | 
![]()  | 
Feature
- Transition zooming animation like the iOS Photos app and the "Pinterest", and so on
 -  Easy to use (conform to 
ImageTransitionableprotocol) - Swifty (protocol-oriented)
 - Animation configuration customizable (animation duration, UIView.AnimationOptions)
 - CornerRadius animation (e.g. from a round image to a square Image)
 
Installation
Carthage
- Add 
github "shtnkgm/ImageTransition"to your Cartfile. - Run carthage update.
 
CocoaPods
- Add 
pod 'ImageTransition'to your podfile. - Run pod update.
 
Usage
- Confirm 
ImageTransitionableprotocol 
// Source UIViewController
import ImageTransition
extension SourceViewController: ImageTransitionable {
    var imageViewForTransition: UIImageView? {
        return imageView
    }
}
// Destination UIViewController
import ImageTransition
extension DestinationViewController: ImageTransitionable {
    var imageViewForTransition: UIImageView? {
        return imageView
    }
}- Set Delegate
 
    // present / dismiss transition
    @objc private func imageViewDidTapped() {
        let destinationViewController = DestinationViewController.make()
        destinationViewController.transitioningDelegate = ImageTransitionDelegate.shared
        present(destinationViewController, animated: true, completion: nil)
    }
    // push / pop transition
    @objc private func imageViewDidTapped() {
        let destinationViewController = DestinationViewController.make()
        // Set ImageTransitionDelegate.shared to `delegate` property of UINavigationContoller
        navigationController?.delegate = ImageTransitionDelegate.shared
        navigationController?.pushViewController(destinationViewController, animated: true)
    }Customize
You can customize the configuration of animation.
ImageTransitionDelegate.shared.presentDuration = 0.5
ImageTransitionDelegate.shared.dismissDuration = 0.5
ImageTransitionDelegate.shared.pushDuration = 0.5
ImageTransitionDelegate.shared.popDuration = 0.5
ImageTransitionDelegate.shared.presentAnimationOptions = [.curveLinear]
ImageTransitionDelegate.shared.dismissAnimationOptions = [.curveEaseIn]
ImageTransitionDelegate.shared.pushAnimationOptions = [.curveLinear]
ImageTransitionDelegate.shared.popAnimationOptions = [.curveEaseIn]Requirements
- iOS 12.0 or later
