objective c - Removing leading zeroes from a string

Question

I have a string 0023525631 but what I want is the string 23525631 -- without the leading zeroes. How do I do this?

Answer 1

Use Reguler Expression like this,

 NSString *str =@"000034234247236000049327428900000";
    NSRange range = [str rangeOfString:@"^0*" options:NSRegularExpressionSearch];
    str= [str stringByReplacingCharactersInRange:range withString:@""];
    NSLog(@"str %@",str);

O/P:-str 34234247236000049327428900000
