CustomBlurEffectView

Customizable blur effect view with blur radius, tint color and tint color alpha.

Requirements

• iOS 9.0+
• Xcode 9.0+
• Swift 5

Usage

Add an instance of CustomBlurEffectView to your view.

import CustomBlurEffectView

let customBlurEffectView = CustomBlurEffectView(
    radius: 20, // Set blur radius value. Defaults to `10` (CGFloat)
    color: .cyan, // Set tint color value. Defaults to `nil` (UIColor?)
    colorAlpha: 0.4 // Set tint color alpha value. Defaults to `0.8` (CGFloat)
)
customBlurEffectView.frame = CGRect(x: 0, y: 0, width: 300, height: 300)
addSubview(customBlurEffectView)

Either you can configure the view different way.

let customBlurEffectView = CustomBlurEffectView()
customBlurEffectView.frame = CGRect(x: 0, y: 0, width: 300, height: 300)
customBlurEffectView.blurRadius = 20
customBlurEffectView.colorTint = .cyan
customBlurEffectView.colorTintAlpha = 0.4
addSubview(customBlurEffectView)

CustomBlurEffectView is inherited from UIView, and UIVisualEffectView is a subview of CustomBlurEffectView. To get UIVisualEffectView layer directly you can use blurLayer property:

let customBlurEffectView = CustomBlurEffectView()
let layer = customBlurEffectView.blurLayer
