title: How to divide fours rows into one section using NSFetchedResultsController?
body: <p>I am new  to ios development as well as core data, but i still tried to understand and manage with basics of these two things. Right now i am in a problem, I know how to fetch data using <code>NSFetchedResultsController</code> and display them in <code>UITableView</code>, but suppose if i have <code>20 rows</code> in data base and if i need to display <code>four rows each in a section</code> how can i do this?. I am not getting what condition is should give for <code>sectionNameKeyPath</code> while building <code>NSFetchedResultsController</code>. Can somebody help me how to do this?.</p>
