title: Tableview and adding buttons to it
body: <p>I have 2 questions.</p>
  <p>1.) I have a tableView, and it will have more than 100 rows (of data). But i will only display 10 records at a time. when the user scrolls down and below the 10th row i want to add a button, which says <code>load the next 10 records</code> and <code>load the previous 10 records</code>. How do i add these buttons ? note: that these buttons only appear when you scroll down to the last record of your table view (I found a similar example in iTunes too)</p>
  <p>2.) I need those 2 buttons to have an arrow shape <a href="http://img.skitch.com/20100513-m9b9g67ftfh8bisgbj3mib9sex.jpg" rel="nofollow noreferrer">(As a Navigation button)</a></p>
  <p>How do i get this done <strong>programatically</strong>. (I will not be using the interface builder to create this)</p>
