DynamicColor provides powerful methods to manipulate colours in an easy way.
Usage
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 = UIColor(hexString: "#c0392b")
let lighterColor = originalColor.lighterColor()
// equivalent to
// lighterColor = originalColor.lightenColor(0.2)
let darkerColor = originalColor.darkerColor()
// equivalent to
// darkerColor = originalColor.darkenColor(0.2)
Saturate, Desaturate & Grayscale
These will adjust the saturation of the color object, much like darkenColor
and lightenColor
adjusted the lightness. Again, you need to use a value between 0 and 1.
let originalColor = UIColor(hexString: "#c0392b")
let saturatedColor = originalColor.saturatedColor()
// equivalent to
// saturatedColor = originalColor.saturateColor(0.2)
let desaturatedColor = originalColor.desaturatedColor()
// equivalent to
// desaturatedColor = originalColor.desaturateColor(0.2)
let grayscaleColor = originalColor.grayscaledColor()
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 = UIColor(hexString: "#c0392b")
let adjustHueColor = originalColor.adjustedHueColor(45 / 360)
let complementColor = originalColor.complementColor()
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 = UIColor(hexString: "#c0392b")
let tintColor = originalColor.tintColor()
// equivalent to
// tintColor = originalColor.tintColor(amount: 0.2)
let shadeColor = originalColor.shadeColor()
// equivalent to
// shadeColor = originalColor.shadeColor(amount: 0.2)
Invert
This can invert the color object. The red, green, and blue values are inverted, while the opacity is left alone.
let originalColor = UIColor(hexString: "#c0392b")
let invertColor = originalColor.invertColor()
Mix
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 = UIColor(hexString: "#c0392b")
let mixColor = originalColor.mixWithColor(UIColor.blueColor())
// equivalent to
// mixColor = originalColor.mixWithColor(UIColor.blueColor(), weight: 0.5)
And many more...
DynamicColor
also provides many another useful methods to manipulate the colors like hex strings, color components, etc. To go further, take a look at the example project.
Installation
CocoaPods
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', '~> 2.3.0'
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
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
To integrate DynamicColor
into your Xcode project using Carthage, specify it in your Cartfile
file:
github "yannickl/DynamicColor" >= 2.3.0
Manually
Download the project and copy the DynamicColor
folder into your project to use it in.
