ImageTransition

Cocoapods Carthage compatible Swift Version GitHub

ImageTransition is a library for smooth animation of images during transitions.

Something looks like below:

e.g. UIImageViewe.g. UIImageView in UICollectionView
sample_01.gifsample_02.gif

Feature

  • Transition zooming animation like the iOS Photos app and the "Pinterest", and so on
  • Easy to use (conform to ImageTransitionable protocol)
  • Swifty (protocol-oriented)
  • Animation configuration customizable (animation duration, UIView.AnimationOptions)
  • CornerRadius animation (e.g. from a round image to a square Image)

Installation

  • Swift Package Manager: https://github.com/shtnkgm/ImageTransition.git
  • Carthage: github "shtnkgm/ImageTransition"
  • CocoaPods: pod "ImageTransition"

Usage

  • Confirm ImageTransitionable protocol
// 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
