ColorAdjuster is the library which can create a new color by HBS or RGB for the cause in base color, and create gradation view.

Demo

• UIColor can regulate numerical value of HBS and RGB of the target color.

• UIView can make gradation of Gradation.
• You can coordinate gradation colors with the number of any colors.

Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

• swift 2.0, iOS8.0 ~

Installation

ColorAdjuster is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "ColorAdjuster"

Example

• Appoint it in hexadecimal and create UIColor.

let color = UIColor(hex: 0xB7EAE7)

HBS

• Ajustment color of HBS.

let adjustmentColor = color.colorWithHBSComponent(hue: hueValue, brightness: brightnessValue, saturation: saturationValue)
adjustmentColorView.backgroundColor = adjustmentColor

• Get HBS value of color.

if let hbs = adjustmentColor?.colorHBS() {
    print("Hue = \(hbs.hue)")
    print("Bridhtness = \(hbs.brightness)")
    print("Saturation = \(hbs.saturation)")
}

RGB

• Ajustment color of RGB.

let adjustmentColor = color.colorWithRGBComponent(red: rValue, green: gValue, blue: bValue)
targetView.backgroundColor = adjustmentColor

• Get RGB value of color.

if let rbg = adjustmentColor?.colorRGB() {
    print("Red = \(rbg.red)")
    print("Green = \(rbg.green)")
    print("Blue = \(rbg.blue)")
}

Create gradation view.

let targetView = UIView(frame: frame)
let colors: [CGColor] = [UIColor.redColor().CGColor, UIColor.magentaColor().CGColor]
view.addSubView(targetView)

Appoint locations

let locations: [CGFloat] = [0.0, 1.0]
targetView.gradientLayer.insertLayerVerticallyGradient(colors: colors, locations: locations)

Appoint startPoint and endPoint

let startPoint = CGPointMake(1, 0.5)
let endPoint = CGPointMake(0, 0.5)
targetView.gradientLayer.insertLayerVerticallyGradient(colors: colors, startPoint: startPoint, endPoint: endPoint)

Appoint Angle = Zero

targetView.gradientLayer.insertLayerVerticallyGradient(colors: colors, angle: .Zero)

Appoint Angle = FortyFive

targetView.gradientLayer.insertLayerVerticallyGradient(colors: colors, angle: .FortyFive)

Appoint Ninety

targetView.gradientLayer.insertLayerVerticallyGradient(colors: colors, angle: .Ninety)

Function

• Appoint it in hexadecimal and create UIColor.

public convenience init(hex: Int, alpha: CGFloat = 1)

• UIColor ajustment color of HBS.

public func colorWithHBSComponent(hue hue: CGFloat, brightness: CGFloat, saturation: CGFloat) -> UIColor?

• UIColor get HBS value of color.

public func colorHBS() -> ColorAdjuster.HBSProperties?

• UIColor ajustment color of RGB.

public func colorWithRGBComponent(r r: CGFloat, g: CGFloat, b: CGFloat) -> UIColor?

• UIColor get RGB value of color.

public func colorRGB() -> ColorAdjuster.RGBProperties?

• UIView create gradation view.

public func insertLayerVerticallyGradient(colors colors: [CGColor], locations: [CGFloat]) 

Properties

• Value of HBS

public struct HBSProperties {
    public var hue: CGFloat = 0
    public var brightness: CGFloat = 0
    public var saturation: CGFloat = 0
    public var alpha: CGFloat = 1
}

• Value of RGB

public struct RGBProperties {
    public var r: CGFloat = 0
    public var g: CGFloat = 0
    public var b: CGFloat = 0
    public var alpha: CGFloat = 1
}
