Iridescent Effect View (inspired by Apple Pay Cash) ✨

Shiny

Shiny is an iOS library that generates an iridescent effect view matched to the gyroscope, similar to the Apple Pay Cash card in the Wallet app.

$ pod try Shiny

Requirements

• iOS 9.0+
• Xcode 9.0+
• Swift 5 (Shiny 2.x), Swift 4 (Shiny 1.x)

Usage

Adding ShinyView programmatically (supports storyboard/xib too):

import Shiny

let shinyView = ShinyView(frame: CGRect(x: 0, y: 0, width: 320, height: 200))
shinyView.colors = [.gray, .red, .green, .blue, .gray]
shinyView.startUpdates() // necessary
view.addSubview(shinyView)

You must call startUpdates() for the instance to observe motion changes. Calling stopUpdates() on the instance will stop motion updates.

func startUpdates() // Starts listening to motion updates.
func stopUpdates() // Stops listening to motion updates.

Customization

The ShinyView exposes several properties to customize the radial gradient used to create the shiny effect:

var colors: [UIColor] // The color of each gradient stop.
var locations: [CGFloat]? // The location of each gradient stop. The default is `nil`.
var scale: CGFloat // The scale factor of the gradient. The default is `2.0`.
