Further documentation available as part of this blog post.
Features
- Easily create animated or static gradients.
- Configurable gradient direction.
- Use hex values, RGB values or names to specify colors (including color names specified in asset catalogs on iOS 11 or higher).
- Supports animating between gradients with a varying number of colors.
- Supports axial, radial and on iOS 12, conic gradients.
- Auto-animate or animate manually using the
startAnimating
andstopAnimating
functions. - Loop animations with the
autoRepeat
property.
To learn more about how to use AnimatedGradientView, check out the blog post, take a look at the example app, the demo over on Appetize.io, or make use of the table of contents below:
What's new in AnimatedGradientView 3.0.0?
AnimatedGradientView 3.0.0 provides support for Xcode 12 and raises the minimum deployment target to iOS 9 (dropping support for iOS 8).
Quickstart
Creating and adding a new AnimatedGradientView
as a subview is as simple as follows:
let animatedGradient = AnimatedGradientView(frame: view.bounds)
animatedGradient.direction = .up
animatedGradient.animationValues = [(colors: ["#2BC0E4", "#EAECC6"], .up, .axial),
(colors: ["#833ab4", "#fd1d1d", "#fcb045"], .right, .axial),
(colors: ["#003973", "#E5E5BE"], .down, .axial),
(colors: ["#1E9600", "#FFF200", "#FF0000"], .left, .axial)]
view.addSubview(animatedGradient)
You'll also need to remember to import the framework using import AnimatedGradientView
.
Requirements
AnimatedGradientView is written in Swift 5.0 and is available on iOS 8.0 or higher.
Installation
Cocoapods
CocoaPods is a dependency manager which integrates dependencies into your Xcode workspace. To install it using RubyGems run:
gem install cocoapods
To install AnimatedGradientView using Cocoapods, simply add the following line to your Podfile:
pod "AnimatedGradientView"
Then run the command:
pod install
For more information see here.
Carthage
Carthage is a dependency manager which produces a binary for manual integration into your project. It can be installed via Homebrew using the commands:
brew update
brew install carthage
In order to integrate AnimatedGradientView into your project via Carthage, add the following line to your project's Cartfile:
github "rwbutler/AnimatedGradientView"
From the macOS Terminal run carthage update --platform iOS
to build the framework then drag AnimatedGradientView.framework
into your Xcode project.
For more information see here.
Swift Package Manager
Swift Package Manager is a dependency manager built right into Xcode 11 and higher. From the File menu, add a new Swift Package dependency to your project and paste in this project's Git URL.
Usage
Static Gradients
If all you need is a gradient without animation this is easily achieved by setting the colors
property to an array of UIColor
as follows:
let gradient = AnimatedGradientView(frame: view.bounds)
gradient.colors = [[UIColor.blue, UIColor.red]]
gradient.direction = .up
view.addSubview(gradient)
The colors
property is actually an array of UIColor
arrays. If further UIColor
arrays are specified then animation will occur between them. Using the direction
property it also possible to define the direction of the gradient.
If it is more convenient to work with hex color strings rather than UIColor
then make use of the colorStrings
property instead as follows:
let gradient = AnimatedGradientView(frame: view.bounds)
gradient.colorStrings = [["#3224AE", "#FF66FF"]]
gradient.direction = .up
view.addSubview(gradient)
Gradient Types
AnimatedGradientView supports three types of gradients which can be set using the type
property.
let gradient = AnimatedGradientView(frame: view.bounds)
gradient.autoAnimate = false
gradient.colorStrings = [["#3224AE", "#FF66FF"]]
gradient.type = .axial
view.addSubview(gradient)
The three gradient types supported are:
Axial
This is your standard linear gradient blending between color stops from the start point to the end point.
<div align="center"> <img width="200" height="200" src="https://github.com/rwbutler/AnimatedGradientView/raw/main/docs/images/axial.png" alt="Axial Gradient"> </div>Radial
The gradient appears to radiate outwards from the start point (at the center) towards the end point in a circular fashion blending between the color stops from the start point to end point as with a linear gradient.
<div align="center"> <img width="200" height="200" src="https://github.com/rwbutler/AnimatedGradientView/raw/main/docs/images/radial.png" alt="Radial Gradient"> </div>Conic
This type of gradient is only available from iOS 12 onwards. It is similar to a radial gradient in that the start point represents the center of the circle and the end point represents a point on the outer edge. However, whilst a radial gradient blends between color stops from the start point to the end point (from the center to the outer edge), a conic gradient places the color stops along the outer edge of the circle blending between the color stops from 0 degrees to 360 degrees.
