Question

I have a many strings, here 3 for example:

1. example old
14. example new
234. example 45

I want to exclude the first numbers and make that:

example old
example new
example 45

What i do is:

   NSString *fixed1 = [str substringWithRange:NSMakeRange(3, [str length]-3)];
   NSString *fixedStr = [fixed1 stringByReplacingOccurrencesOfString:@". " withString:@""];

And what i got is:

example old
 example new
example 45

The problem is the space at the start of “example new”. I don’t know how to remove it, if i try this:

 NSString *fixed1 = [str substringWithRange:NSMakeRange(3, [str length]-3)];
 NSString *fixed2 = [fixed1 stringByReplacingOccurrencesOfString:@". " withString:@""];
 NSString *fixedStr = [fixed2 stringByReplacingOccurrencesOfString:@" " withString:@""];

I got this:

exampleold
examplenew
example45

Im going crazy with this, please someone have a nice & simple idea how to solve it?

Thanks!

You can use

- (NSString *)stringByTrimmingCharactersInSet:(NSCharacterSet *)set

with [NSCharacterSet whitespaceCharacterSet] as a parameter to shave off spaces at the beginning and the end.
