This code SHOULD clean phone number, but it doesn’t: NSLog(@%@, self.textView.text); // Output +358

This code SHOULD clean phone number, but it doesn’t:

NSLog(@"%@", self.textView.text);
// Output +358 40 111 1111
NSString *s = [self.textView.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSLog(@"%@", s);
// Output +358 40 111 1111

Any ideas what is wrong? Any other ways to remove whitespacish characters from text string (except the hard way)?

    Try this 

    NSCharacterSet *dontWantChar = [NSCharacterSet whitespaceAndNewlineCharacterSet];
NSString *string = [[self.textView.text componentsSeparatedByCharactersInSet:dontWantChar] componentsJoinedByString:@""];
