title: How would I convert an NSMutableArray filled of UNIX dates to standard dates?
body: <p>I have an NSMutableArray filled up of UNIX dates (1305410327), and I want to convert all of them to readable dates like Fri, 06 Feb 2009 07:28:06 +0000. I'm so lost and this is the code I have:</p>
  
  <pre><code>NSDate *fulltime = [NSDate dateWithTimeIntervalSince1970:[time objectAtIndex:indexPath.row]];
  </code></pre>
  
  <p>But gives me next error when compiling:</p>
  
  <pre><code>error: incompatible type for argument 1 of 'dateWithTimeIntervalSince1970:'
  </code></pre>
  
  <p>So I don't know how to make it work. Thanks all in advance! :)</p>
