Setting UINavigationbar properties in viewDidLoad does nothing
<p>I've tried setting the style of the UINavigationbar to be a translucent style in the viewDidLoad method of my controller. But nothing is changed. Why?</p>

<p>I set the property using the standard code like</p>

<pre><code>self.navigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent;
</code></pre>
