iOS十六进制颜色码转换成RGB颜色值

OC代码

#define UIColorFromRGB(rgbValue,alphaValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 \
green:((float)((rgbValue & 0xFF00) >> 8))/255.0 \
blue:((float)(rgbValue & 0xFF))/255.0 \
alpha:alphaValue]

swift代码

func UIColorFromRGB(_ rgbValue:Int,_ alphaValue:CGFloat) -> UIColor {
    return UIColor(red: CGFloat(((Float)((rgbValue & 0xFF0000) >> 16))/255.0) , green: CGFloat(((Float)((rgbValue & 0xFF00) >> 8))/255.0), blue: CGFloat(((Float)(rgbValue & 0xFF))/255.0), alpha: alphaValue)
}
