[swift]RGB値でUIColorを作成するextension

swiftのUIColorがデフォルトでは0~1.0の値をしてしてインスタンスを作成する仕様になっていて、微妙に使いづらいなと思ったので作った。
ついでにextensionにアプリでよく使う色を定義すると使いやすい。

UIColorExtension.swift
import UIKit

extension UIColor {
    class func rgb(#r: Int, g: Int, b: Int, alpha: CGFloat) -> UIColor{
        return UIColor(red: CGFloat(r) / 255.0, green: CGFloat(g) / 255.0, blue: CGFloat(b) / 255.0, alpha: alpha)
    }
    class func MainColor() -> UIColor {
        return UIColor.rgb(r: 24, g: 135, b: 208, alpha: 1.0)
    }
}
