swift / ColorコードをUIColorに変換

    func colorWithRGBHex(hex:Int,alpha: Float = 1.0) -> UIColor{
        let r = Float((hex >> 16) & 0xFF);
        let g = Float((hex >> 8) & 0xFF);
        let b = Float((hex ) & 0xFF);
        return UIColor(
            red: CGFloat(r / 255.0),
            green: CGFloat(g / 255.0),
            blue: CGFloat(b / 255.0),
            alpha: CGFloat(alpha))
    }

使い方

        let arryColors = [
            colorWithRGBHex(0xFFFFFF,alpha:1.0).CGColor as AnyObject,
            colorWithRGBHex(0xCCCCCC,alpha:1.0).CGColor as AnyObject
        ];
