title: Setting font and font-size of title bar text in a UITableViewController
body: <p>I have a simple navigation based application for the iphone/objective-c</p>
  
  <p>within various UIViewControllers that are pushed into view, I can set the text in the title bar using something like</p>
  
  <pre><code>self.title = @"blah blah blah"
  </code></pre>
  
  <p>Is there a way to control the <strong>font</strong> and <strong>font-size</strong> of the title in the title bar text?</p>
  
  <p>thanks!</p>
