title: UITableView reload data
body: <p>i'm making a navigation based application for iphone.</p>
  
  <p>one of my view controllers looks like this:</p>
  
  <pre><code>@interface NewComputerViewController : UIViewController &lt;UITableViewDelegate, UITableViewDataSource&gt;
  </code></pre>
  
  <p>so i'm using a <code>UITableView</code> to show data.</p>
  
  <p>when the view loads, I use a button in the top navigation bar to run a function <code>loadStuff</code> load some stuff in a Dictionary.</p>
  
  <p>My question: how do I repopulate the table view in that viewcontroller from that <code>loadStuff</code> function (which belongs to the view controller)</p>
