How to convert HEX to NSString in Objective-C?

Question

I have a NSString with hex string like \"68656C6C6F\" which means \"hello\".

Now I want to convert the hex string into another NSString object which shows \"hello\"

I think the people advising initWithFormat is the best answer as it's objective-C rather than a mix of ObjC, C.. (although the sample code is a bit terse).. I did the following

unsigned int resInit = 0x1013;
if (0 != resInit)
{
    NSString *s = [[NSString alloc] initWithFormat:@"Error code 0x%lX", resInit];
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Initialised failed"
        message:s
        delegate:nil
        cancelButtonTitle:@"OK"
        otherButtonTitles:nil];
    [alert show];
    [alert release];
    [s release];
}
