title: NSMutableArray - Add array at start
body: <p>It is a simple pull to refresh case. I have data loaded into table and have a mutable data array at back-end, I receive a array of new data and want to add this complete array at start of existing array. </p>
  
  <p>One workaround is to create new array with new arrived data and then add previous array into it using  <code>addObjectsFromArray:</code> method. Is there some workaround to add new data array to the start of previous array directly?</p>
