title: NSDateFormatter dateFromString
body: <p>The string which comes from my data source is formatted like this:</p>
  
  <blockquote>
    <p>2011-04-11 23:12:05</p>
  </blockquote>
  
  <pre><code>// dateString comes from my data source, and look like I've said like this.
  dateString = @"2011-04-11 23:12:05";
  
  NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
  [formatter setDateFormat:@"MMMM"];
  
  NSDate *date = [formatter dateFromString:dateString];
  </code></pre>
  
  <p>When I've searched internet after threads like these the answer has always been that the dateString had wrong format. But my dateString is one of the correct ones, right?</p>
  
  <p>Why does date returns nil?</p>
