ShadowView is an iOS Shadow library that makes view's shadow implementation easy and sweet 🎉 🎊.

Add simple shadows to add a gaussian blurred projection (as a shadow) to any UIView.

• Add shadow easily from the storyboard and programmatically.
• Add a gaussian blurred projection of your view (like iOS 10 music app).
• Customize the border width and border color of any view from storyboard .

• iOS 9.0+
• Xcode 8

You can use CocoaPods to install ShadowView by adding it to your Podfile:

source 'https://github.com/CocoaPods/Specs.git' platform :ios, '9.0' use_frameworks! target '<Your Target Name>' do pod 'ShadowView' end

1. Install Carthage via Homebrew

$ brew update $ brew install carthage

2. Add github "PierrePerrin/ShadowView" to your Cartfile.

3. Run carthage update.

4. Drag ShadowView.framework from the Carthage/Build/iOS/ directory to the Linked Frameworks and Libraries section of your Xcode project’s General settings.

5. Add $(SRCROOT)/Carthage/Build/iOS/ShadowView.framework to Input Files of Run Script Phase for Carthage.

1. Download and drop all files in ShadowView directory in your project.
2. Nice Job the best shadow library is now installed! 🎉 🎊 🎈

To get the full benefits import ShadowView wherever you import UIKit

import UIKit import ShadowView

This shadow framework uses default CoreGraphics shadows by adding it the the layer of the view.

layer.shadowColor : CGColor layer.shadowRadius : CGFloat layer.shadowOffset : CGSize layer.shadowOpacity : Float layer.shadowPath : CGPath?

Here the implemation is different. A shadow container need to be added and all views that needs a blurred shadow need to be subviews of this container. The container takes a screen of all it's subviews and then apply blur on it.

Any view has new paramerters in the storyboar that you can change in order to add a customize shadow to your view.

Add an UIView to you ViewController, change it class to ShadowView and insert in it all view that needs a blurred shadow.

Set the shadows parameters to your view and it the shadow will appear! 🌟

view.shadowRadius = 5 view.shadowOffset = CGSize.zero view.shadowColor = UIColor.black.cgColor view.shadowOpacity = 0.3

Create you container ShadowView and then add views that need Shadows inside of it.

 let exampleShadowContainerView = ShadowView() let imageView = UIImageView(image: #imageLiteral(resourceName: "sample.jpg")) override func loadView() { super.loadView() exampleShadowContainerView.frame = self.view.bounds exampleShadowContainerView.autoresizingMask = [.flexibleWidth,.flexibleHeight] exampleShadowContainerView.shadowOffset = CGSize(width: 0, height: 10) exampleShadowContainerView.shadowRadius = 20 self.view.addSubview(exampleShadowContainerView) self.exampleShadowContainerView.addSubview(imageView) imageView.center = exampleShadowContainerView.center } override func viewDidLayoutSubviews() { super.viewDidLayoutSubviews() imageView.frame.size = CGSize(width: 200, height: 200) imageView.center = exampleShadowContainerView.center self.exampleShadowContainerView.updateShadow() }

Please see the example for more prescisions.

//Shared Paramerters @IBInspectable public var shadowRadius : CGFloat @IBInspectable public var shadowOffset : CGSize @IBInspectable public var shadowColor : UIColor? @IBInspectable public var shadowOpacity : Float //Normal Shadow @IBInspectable var shadowPath : CGPath? //ShadowView only ///It changes the size of the projected shadow view. @IBInspectable var shadowScale : CGFloat ///Changes the tint color of the blurred image @IBInspectable var shadowTintColor : UIColor ///Changes the saturation of the blurred image (default:1) @IBInspectable var shadowSaturation : CGFloat

Don't use Views like Sliders or ActivityIndicators, the shadow don't update un real-time. It's preferable to use statics Views like Labels, images...
