Image Contents

Say you want to toggle a few images in your app. Instead of hiding / revealing multiple images using the hidden property, you can create a extra “container” image whose contents you set.

image.contents = anotherImage.contents

Example

let chop = Image("chop")!
let rockies = Image("rockies")!

let visibleImage = Image(c4image: chop)
visibleImage.constrainsProportions = true
visibleImage.width = canvas.width
canvas.add(visibleImage)

var isFirst = true
canvas.addTapGestureRecognizer { (center, location, state) -> () in
    if isFirst {
        visibleImage.contents = rockies.contents
    } else {
        visibleImage.contents = chop.contents
    }
    isFirst = !isFirst
}
