title: preferredStatusBarStyle and presentModalView Controllers
body: <pre><code>@implementation UIViewController (preferredStatusBar)
  -(UIStatusBarStyle) preferredStatusBarStyle
  {
      return UIStatusBarStyleLightContent;
  }
  @end
  </code></pre>
  
  <p>I made this category so all the controllers implements this attribute, <code>UIStatusBarStyleLightContent</code> can change during application.</p>
  
  <p>Everything works fine except for modal controllers. They ignore completely status bar style.</p>
