A swift implementation of Facebooks shimmer effect.
This project is no longer under active development. It's stable and should still be good to use for a number of years. I'm moving my efforts into SwiftUI.
- Swift 5.1+
- iOS 9.0+
Download the .zip from this repo and drag the Shimmer folder into your project.
Add github "BeauNouvelle/ShimmerSwift" to your Cartfile.
Add pod 'ShimmerSwift' to your Podfile.
In Xcode 11 you can add packages by going to File > Swift Packages > Add Package Dependency. Copy in this repos URL and go from there.
Shimmer is super easy to get started with.
Simply create a ShimmeringView or ShimmeringLayer and add your content.
// Setup ShimmeringView
let shimmerView = ShimmeringView(frame: self.view.bounds)
self.view.addSubview(shimmerView)
// Setup the view you want shimmered
let label = UILabel(frame: shimmerView.bounds)
label.text = "This is my shimmering text"
// Add the view you want shimmered to the `shimmerView`
shimmerView.contentView = label
// Start shimmering
shimmerView.isShimmering = true
// To stop shimmering.
shimmerView.isShimmering = false
All customizable properties are well documented in code, and are reproduced below.
The content view to be shimmered
contentView: UIView
Set to true to start shimmer animation, and false to stop. Detaults to false.
isShimmering: Bool
The speed of the shimmer animation in points per second. The higher the number, the faster the animation.
Defaults to 230.
shimmerSpeed: CGFloat
The highlight length of the shimmer. Range of [0,1], defaults to 1.0.
shimmerHighlightLength: CGFloat
The direction of the shimmer animation.
Defaults to .right, which will run the animation from left to right.
shimmerDirection: Shimmer.Direction
The time interval between shimmers in seconds. Defaults to 0.4.
shimmerPauseDuration: CFTimeInterval
The opacity of the content during a shimmer. Defaults to 0.5.
shimmerAnimationOpacity: CGFloat
The opacity of the content when not shimmering. Defaults to 1.0.
shimmerOpacity: CGFloat
The duration of the fade used when the shimmer begins. Defaults to 0.1.
shimmerBeginFadeDuration: CFTimeInterval
The duration of the fade used when the shimmer ends. Defaults to 0.3.
shimmerEndFadeDuration: CFTimeInterval
