DynamicColor provides powerful methods to manipulate colors in an easy way in Swift.
- iOS 8.0+ / Mac OS X 10.9+ / tvOS 9.0+ / watchOS 2.0+
- Xcode 9.1+
- Swift 4.0+
Creation (Hex String)
Firstly, DynamicColor provides useful initializers to create colors using hex strings or values:
let color = UIColor(hexString: "#3498db") // equivalent to // color = UIColor(hex: 0x3498db)
To be platform independent, the typealias
DynamicColor can also be used:
let color = DynamicColor(hex: 0x3498db) // On iOS, WatchOS or tvOS, equivalent to // color = UIColor(hex: 0x3498db) // On OSX, equivalent to // color = NSColor(hex: 0x3498db)
Darken & Lighten
These two create a new color by adjusting the lightness of the receiver. You have to use a value between 0 and 1.
let originalColor = DynamicColor(hexString: "#c0392b") let lighterColor = originalColor.lighter() // equivalent to // lighterColor = originalColor.lighter(amount: 0.2) let darkerColor = originalColor.darkened() // equivalent to // darkerColor = originalColor.darkened(amount: 0.2)
Saturate, Desaturate & Grayscale
These will adjust the saturation of the color object, much like
lighter adjusted the lightness. Again, you need to use a value between 0 and 1.
let originalColor = DynamicColor(hexString: "#c0392b") let saturatedColor = originalColor.saturated() // equivalent to // saturatedColor = originalColor.saturated(amount: 0.2) let desaturatedColor = originalColor.desaturated() // equivalent to // desaturatedColor = originalColor.desaturated(amount: 0.2) let grayscaledColor = originalColor.grayscaled()
Adjust-hue & Complement
These adjust the hue value of the color in the same way like the others do. Again, it takes a value between 0 and 1 to update the value.
let originalColor = DynamicColor(hex: 0xc0392b) // Hue values are in degrees let adjustHueColor = originalColor.adjustedHue(amount: 45) let complementedColor = originalColor.complemented()
Tint & Shade
A tint is the mixture of a color with white and a shade is the mixture of a color with black. Again, it takes a value between 0 and 1 to update the value.
let originalColor = DynamicColor(hexString: "#c0392b") let tintedColor = originalColor.tinted() // equivalent to // tintedColor = originalColor.tinted(amount: 0.2) let shadedColor = originalColor.shaded() // equivalent to // shadedColor = originalColor.shaded(amount: 0.2)
This can invert the color object. The red, green, and blue values are inverted, while the opacity is left alone.
let originalColor = DynamicColor(hexString: "#c0392b") let invertedColor = originalColor.inverted()
This can mix a given color with the receiver. It takes the average of each of the RGB components, optionally weighted by the given percentage (value between 0 and 1).
let originalColor = DynamicColor(hexString: "#c0392b") let mixedColor = originalColor.mixed(withColor: .blue) // equivalent to // mixedColor = originalColor.mixed(withColor: .blue, weight: 0.5) // or // mixedColor = originalColor.mixed(withColor: .blue, weight: 0.5, inColorSpace: .rgb)
DynamicColor provides an useful object to work with gradients: DynamicGradient. It'll allow you to pick color from gradients, or to build to build a palette using different color spaces (.e.g.: RGB, HSL, HSB, Cie L*a*b*).
Let's define our reference colors and the gradient object:
let blue = UIColor(hexString: "#3498db") let red = UIColor(hexString: "#e74c3c") let yellow = UIColor(hexString: "#f1c40f") let gradient = DynamicGradient(colors: [blue, red, yellow]) // equivalent to // let gradient = [blue, red, yellow].gradient
Let's build the RGB palette (the default color space) with 8 colors:
let rgbPalette = gradient.colorPalette(amount: 8)
Now if you want to change the gradient color space to have a different effect, just write the following lines:
let hslPalette = gradient.colorPalette(amount: 8, inColorSpace: .hsl)
Or if you prefer to work directly with array of colors, you can:
let labPalette = [blue, red, yellow].gradient.colorPalette(amount: 8, inColorSpace: .lab)
And many more...
DynamicColor also provides many another useful methods to manipulate the colors like hex strings, color components, color spaces, etc. To go further, take a look at the example project.
Install CocoaPods if not already available:
$ [sudo] gem install cocoapods $ pod setup
Go to the directory of your Xcode project, and Create and Edit your Podfile and add DynamicColor:
$ cd /path/to/MyProject $ touch Podfile $ edit Podfile source 'https://github.com/CocoaPods/Specs.git' platform :ios, '8.0' use_frameworks! pod 'DynamicColor', '~> 4.0.2'
Install into your project:
$ pod install
Open your project in Xcode from the .xcworkspace file (not the usual project file):
$ open MyProject.xcworkspace
You can now
import DynamicColor framework into your files.
Carthage is a decentralized dependency manager that automates the process of adding frameworks to your Cocoa application.
You can install Carthage with Homebrew using the following command:
$ brew update $ brew install carthage
DynamicColor into your Xcode project using Carthage, specify it in your
github "yannickl/DynamicColor" >= 4.0.2
Swift Package Manager
You can use The Swift Package Manager to install
DynamicColor by adding the proper description to your
import PackageDescription let package = Package( name: "YOUR_PROJECT_NAME", targets: , dependencies: [ .Package(url: "https://github.com/yannickl/DynamicColor.git", versions: "4.0.2" ..< Version.max) ] )
Download the project and copy the
DynamicColor folder into your project to use it in.
