Question

I’m taking a hex color value received as a string and converting it to an int so that I can get the proper hex values. I have the following code underneath my imports:

@implementation NSString (HexIntValue)

- (unsigned int)hexIntValue
{

    NSScanner *scanner;
    unsigned int result;

    scanner = [NSScanner scannerWithString: self];  
    [scanner scanHexInt: &result];

    return result;

}

@end

and then the function is called on a string here:

unsigned int x = (int)[globalBGColor hexIntValue];

Everything works fine, but I really want to get rid of the warning because I’m more or less prepared to submit my app.

Thanks!

I would toss your category in another file. The convention would be to name it “NSSting+HexIntValue.h”. Then make sure you #import it. Should clear everything up.
