SwiftyShadow

Codacy Badge

Helper Libraries to generate wonderful shadow in Swift iOS.

Screenshots

Requirements

  • iOS 8.0+
  • Xcode 8+
  • Swift 4.2

Installation

CocoaPods

To integrate PhotoCollectionView into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

pod 'SwiftyShadow', '~> 1.7.0'

Then, run the following command:

$ pod install

Manually

  • Drag and drop Sources folder into your project.

Usage

Inner Shadow in View

Use SwiftyInnerShadowView class as UIView to make this View has inner shadow.

  • Use Storyboard

Set SwiftyInnerShadowView as UIView Class in the storyboard:

then make an outlet

@IBOutlet weak var testView: SwiftyInnerShadowView!
  • inner shadow properties Set inner shadow propeties through shadowLayer of SwiftyInnerShadowView
testView.shadowLayer.shadowRadius = 4
testView.shadowLayer.shadowColor = UIColor.red.cgColor
testView.shadowLayer.shadowOpacity = 0.8
testView.shadowLayer.shadowOffset = CGSize.zero
testView.cornerRadius = 120

Outer Shadow in View

You can set up outer shadow in view with default properties in UIView

imageView.layer.cornerRadius = 120
imageView.layer.shadowRadius = 20
imageView.layer.shadowOpacity = 0.8
imageView.layer.shadowColor = UIColor.black.cgColor
imageView.layer.shadowOffset = CGSize.zero

but shadow doesn't work if view has clipsToBounds = true, so just call generateOuterShadow function

imageView.generateOuterShadow()

Elliptical Shadow

You need set up shadow properties first, then call generateEllipticalShadow

imageView.layer.shadowRadius = 20
imageView.layer.shadowOpacity = 0.8
imageView.layer.shadowColor = UIColor.black.cgColor
imageView.layer.shadowOffset = CGSize.zero
        
imageView.generateEllipticalShadow()
