title: How to get middle string characters?
body: <p>I have a string that is a date, like this <code>@"dd/mm/yyyy"</code> and I want to split this string in 3 small strings with day, month and year. I've succeeded on doing it with the day using this code:</p>
  
  <pre><code>self.dayLabel.text = [string substringToIndex:2];
  </code></pre>
  
  <p>but how do I get the middle values, like the month?</p>
