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);
