title: Why whitespaceAndNewlineCharacterSet doesn't remove spaces?
body: <p>This code SHOULD clean phone number, but it doesn't:</p>
  
  <pre><code>NSLog(@"%@", self.textView.text);
  // Output +358 40 111 1111
  NSString *s = [self.textView.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
  NSLog(@"%@", s);
  // Output +358 40 111 1111
  </code></pre>
  
  <p>Any ideas what is wrong? Any other ways to <strong>remove whitespacish characters</strong> from text string (except the hard way)?</p>
