title: How do I create a UIViewController programmatically?
body: <p>I am working in a app where i have data in <code>UITableView</code>. It is like a drill down application. User will click on a row and will go to next page showing more records in a <code>UITableView</code>. But problem in my case is that i dont know upto how many level user can drill. The number of levels are not fixed. So now i am thinking to create and add the viewcontrollers programmatically. Is it possible?? if yes how? 
      thanks in advance.</p>
