NSScanner has
- (BOOL)scanHexInt:(unsigned *)value; // Optionally prefixed with
"0x" or "0X"
- (BOOL)scanHexLongLong:(unsigned long long *)result;
so you can
unsigned yourValueHere;
BOOL success = [[NSScanner scannerWithString:string]
scanHexInt:&yourValueHere];

In NSString theres -intValue, -floatValue, -doubleValue, but no -
hexValue (that I can find). I'd like to convert ascii hex NSStrings
(@"001A4CD3" etc) into integer values. Having a -hexValue method
would make that a snap. If theres no Cocoa way, I guess I could try
my hand at writing a category(?) method on NSString using sscanf
with %x.
