Objective c string formatter for distances

Question

I have a distance as a float and I\'m looking for a way to format it nicely for human readers. Ideally, I\'d like it to change from m to km as it gets bigger, and to round the n

Answer 1

found this today asking the same question....going with :

 NSString *rvalue;
    if (value > 1000) {
        rvalue = [NSString stringWithFormat:@"%.02f km",value];
    }else {
        rvalue = [NSString stringWithFormat:@"%.02f m",value];
    }

could wrap this in a method, if need be
