title: Stop current NSURLConnection
body: <p>Currently, I am making an <code>NSURLConnection</code> whenever <code>mySearchBar.text</code> did change. I am experiencing an issue whereby if the user enters text too quickly, The <code>respondData</code> gets corrupted.</p>
  
  <p>So, I was wondering is there a way to check whether the same <code>NSURLConnection</code> is still loading? If yes, How do I drop the current connection and start a new one?</p>
