Demo Animation

You can see above demo project code. demo project code

Usage

  • First, You have to define HorizontalParallaxScrollView object.
let view = UIView(...)
let item = HorizontalParallaxScrollViewItem(view: view,
originOffset: CGPoint(x: 150, y: 80),
acceleration: HorizontalParallaxAcceleration.invariable(CGPoint(x: 1, y: 1)),
progress: { (parallaxView, view) in
//...
}
)

If you want, You can define a dynamic acceleration.

let dynamicAcceleration = HorizontalParallaxAcceleration.variable { (parallaxView, view) -> CGPoint in
let progressRatio = (parallaxView.contentSize.width - 3 * parallaxView.contentOffset.x) / parallaxView.contentSize.width
return CGPoint(x: 0.65 * progressRatio, y: 0.65 * (1 - progressRatio))
}

let view = UIView(...)
let item = HorizontalParallaxScrollViewItem(view: view,
originOffset: CGPoint(x: 150, y: 80),
acceleration: dynamicAcceleration,
progress: { (parallaxView, view) in
//...
}
)
  • Second, Build a parallaxView.
let parallaxView = HorizontalParallaxScrollViewBuilder.setOption { (option) in
option.frame = CGRect(x: 0, y: 100, width: view.frame.size.width, height: view.frame.size.height - 100)
option.parallaxViewItems = [item] // You can add more items.
option.isPagingEnabled = false
}.build()
parallaxView.delegate = self //Optional
