I came up with a similar solution, but different:
I prepend the string (Note that I just add "1" in the format itself)
NSString* theString = [NSString stringWithFormat:@"1%0.4lf", aValue];
theString = [theString stringByTrimmingCharactersInSet:...
// Where we differ is that I now use substringWithRange:
short len = [theString length];
theString = [theString substringWithRange:NSMakeRange(1, len-1)];
// I then apply the removal of the decimal separator
return [theString stringByTrimmingCharactersInSet:[NSCharacterSet
characterSetWithCharactersInString:(NSString *)[[NSUserDefaults
standardUserDefaults] objectForKey:NSDecimalSeparator]]];
Does anyone know which one might be better--i.e., is substringWithRange (+
the length call) costlier than stringByTrimmingCharactersInSet or is it the
other way around?
Thanks!
