title: Getting the last word of an NSString
body: <p>As the title suggests, I would like to get the last word out of an NSString.
  I thought using this code:</p>
  
  <pre><code>NSArray *listItems = [someNSStringHere componentsSeparatedByString:@" "];
  NSString *lastWordString = [NSString stringWithFormat:@"%@", listItems.lastObject];
  anotherNSStringHere = lastWordString;
  </code></pre>
  
  <p>But I think the NSArray will take a time to load if it's big (and it is big), and it wouldn't recognize a word separated by a comma.</p>
  
  <p>Thanks for helping!</p>
