title: How can I set a UITableView to grouped style
body: <p>I have a <code>UITableViewController</code> subclass with sections. The sections are showing with the default style (no rounded corners). How can I set the TableView style to grouped in the code? I'm not using Interface Builder for this, so I need something like</p>
  
  <pre><code>[self.tableView setGroupedStyle]
  </code></pre>
  
  <p>I searched on Stack Overflow, but couldn't come up with an answer.</p>
