A shorthand for creating UIColor object from components

UIColor+ColorComponents.swift

import UIKit

extension UIColor {

    class func colorWithComponents(red redComponent: Float, green: Float, blue: Float, alpha: Float) -> UIColor {
        let r: CGFloat = CGFloat(redComponent/255.0)
        let g: CGFloat = CGFloat(green/255.0)
        let b: CGFloat = CGFloat(blue/255.0)
        let a: CGFloat = CGFloat(alpha)
        return UIColor(red: r, green: g, blue: b, alpha: a)
    }
}
