Colortools adds some methods and properties to UIColor. Let's look at the properties!
public var hue: Double? // Returns a UIColor's hue
public var saturation: Double? // Returns a UIColor's saturation
public var brightness: Double? // Returns a UIColor's brightness
public var alpha: Double? // Returns a UIColor's alpha value
public var red: Double? // Returns a UIColor's red component
public var green: Double? // Returns a UIColor's green component
public var blue: Double? // Returns a UIColor's blue component
public var white: Double? // Returns a UIColor's white component, if it's a greyscale UIColor.But what about the methods? CHECK THESE OUT:
public func getHsba() -> (hue:Double, saturation:Double, brightness:Double, alpha:Double)?
// Returns an optional tuple with the named HSBA components
public func getRgba() -> (red:Double, green:Double, blue:Double, alpha:Double)?
// Returns an optional tuple with the named RGBA components
public func getGreyscale() -> (white:Double, alpha:Double)?
// Returns an optional tuple with the named greyscale components
public func lighten(amount:Double) -> UIColor?
// Returns an optional UIColor with the brightness raised by a number between 0.0 and 1.0
public func scaleLighten(amount:Double) -> UIColor?
// Returns an optional UIColor with the brightness raised a percentage of the
// way to 1.0. (i.e. scaleLighten(0.5) on a UIColor with a brightness of 0.5 will
// return a UIColor with a brightness of 0.75 -- 50% of the way to 1.0
public func darken(amount:Double) -> UIColor?
// The opposite of lighten
public func scaleDarken(amount:Double) -> UIColor?
// The opposite of scaleLighten
public func tint(amount:Double) -> UIColor?
// Takes a double between 0.0 and 1.0, and adds the corresponding amount of
// white to the color. This is kind of like lighten, but different. Try it.
public func shade(amount:Double) -> UIColor?
// The opposite of tint, this adds black to a color
public func saturate(amount:Double) -> UIColor?
// Takes a double between 0.0 and 1.0 and raises the saturation accordingly
public func desaturate(amount:Double) -> UIColor?
// The opposite of saturate
public convenience init(hex:UInt32)
// This takes a hexadecimal number of RRGGBBAA format. Observe:
let green = UIColor.init(hex:0x00FF00FF)
let semiTransparentRed = UIColor.init(hex:0xFF000088)
let orange = UIColor.init(hex:0xF27935FF)
// And so on.To run the tests, clone the repo, and run pod install from the Example directory first.
