I have some xml where an rgb color value is specified via a "#XXYYZZ" type string. The xml is being read in via NSXMLParser. I can't seem to find an easy Cocoa way to convert this value to an unsigned int. I need an unsigned int rather than an NSColor as the value is used in C++ code. Does anyone know of something I may be missing?


Something like this?

//assume colorString is something like @"#AABBCC"

unsigned colorCode = 0;
unsigned char redByte, greenByte, blueByte;

if (nil != colorString)
{
	NSScanner* scanner = [NSScanner scannerWithString:colorString];
	(void) [scanner scanHexInt:&colorCode];
}
redByte   = (unsigned char)(colorCode >> 16);
greenByte = (unsigned char)(colorCode >> 8);
blueByte  = (unsigned char)(colorCode);
