Cunqi / CXImageViewer

An iOS image viewer support zoom in/out behavior just like native photos image viewer

CXImageViewer

An image viewer created for both plain swift and swiftUI use.

It supports zoom in / out logic which mimics ios native photos app

• double tap to zoom in, the image viewer will try to track the tapped location as close as possible
• support pinch gesture recognizer to zoom in / out image
• allow customizing maximumZoomScale

To use the component, there are two scenarios:

Swift

let image = // prepare image
let imageViewer = CXImageViewer()
imageViewer.image = image
imageViewer.maximumZoomScale = 4.0

SwiftUI

CXImageViewer(image: $image, zoomLevel: .constant(1.0))
                    .maxZoomLevel(4.0)
