objective c - NSString by removing the initial zeros?

Question

How can I remove leading zeros from an NSString?

e.g. I have:

NSString *myString;

with values such as @"0002060", @"00236" and @"21456".

I want to remove any leading zeros if they occur:

e.g. Convert the previous to @"2060", @"236" and @"21456".

Thanks.

For smaller numbers:

NSString *str = @"000123";      
NSString *clean = [NSString stringWithFormat:@"%d", [str intValue]];

For numbers exceeding int32 range:

NSString *str = @"100004378121454";     
NSString *clean = [NSString stringWithFormat:@"%d", [str longLongValue]];
