vegather / BlurryOverlayView.swift
Last active February 26, 2024 16:06
A simple view to animate in and out a blurry overlay. Use .blurIn() and .blurOut() to animate the blur. User interaction is passed through when the view is not blurry. NOTE: If you use storyboards, you need to drag out a UIVisualEffectView and set the class. It doesn't work if you drag out a plain old UIView.
class BlurryOverlayView: UIVisualEffectView {
private var animator: UIViewPropertyAnimator!
private var delta: CGFloat = 0 // The amount to change fractionComplete for each tick
private var target: CGFloat = 0 // The fractionComplete we're animating to
private(set) var isBlurred = false
private var displayLink: CADisplayLink!
override init(effect: UIVisualEffect?) {
super.init(effect: effect)
setup()
