Using NSScanner to convert Hex to RGB Color
I’ve found that defining a custom UIColor using RGB values is a little counter intuitive compared to the more common hexadecimal notation used in CSS. This is particularly true if you want to define a color value in a file and don’t want to have to split it into three separate values.
