InteractiveImageView

InteractiveImageView is an open-source library that provides experience showing images like a Photos App on iPhone. (Tap to zoom, pinch and pan gestures, rotation with keep position, motion inertia). The view supports UIKit and SwiftUI framework.

Usage

SwiftUI

@State var tapLocation: CGPoint = .zero
InteractiveImage(image: .init(named: "Iceland"), zoomInteraction: .init(location: tapLocation, scale: 1.2, animated: true)

SwiftUI before iOS 16 didn't support touch location detection. To zoom to the touch location, you could use the Gestures package.

.onTouchGesture(count: 2) { gesture in
  tapLocation = gesture.location
}

UIKit

var interactiveImageView = InteractiveImageView(maxScale: 2.0)
interactiveImageView.image = UIImage(named: "Iceland")

func gestureHandler(_ sender: UITapGestureRecognizer) {
  let location = sender.location(in: imageView)
  interactiveImageView.zoom(to: location, scale: 2.0, animated: true)
}
