title: auto resize height of UIToolbar in landscape orientation
body: <p>I've got a custom UIToolBar which doesn't adjust it's height to match the navigationbar on the top of the screen when I rotate to landscape mode. The height stays the same which makes it look a bit weird. The default toolbar from the UINavigationController actually reduces in size when rotated to landscape (unfortunately I can't use it because of push/pop transition issues). The current resizing mask is : </p>
  
  <pre><code>[ customToolbar setAutoresizingMask: ( UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin ) ];
  </code></pre>
  
  <p>If I add "UIViewAutoresizingFlexible<b>Height</b>" strange things happen...so I'm not quite sure if I should use this.</p>
  
  <p>Please let me know if anyone knows the correct way to auto resize/rotate the UIToolBar to match the navigationbar height.</p>
