title: why was content height of UIWebView not change with rotation
body: <p>Why does the content height of my UIWebView not change with rotation?</p>
  
  <p>From Portrait to Landscape, the content width should expand and the content height should shrink.  It does visually as it should, but not according to my NSLog.</p>
  
  <p>Critical added info about my UIView.</p>
  
  <p>1) my UIWebView is not the whole UIView, but a sub-view of my overall UIView.</p>
  
  <p>2) with the first-swipe through my code, I change the frame.size.height of the UIWebView to the UIWebView's contentHeight via:</p>
  
  <pre><code>UIScrollView *scrollViewInsideWebView = [[webView_ subviews] lastObject];
  webViewContentHeight = scrollViewInsideWebView.contentSize.height;
  </code></pre>
  
  <p>Okay, we then push our UIButton below it ... everything works as it should with Portrait.</p>
  
  <p>Then I rotate it to Landscape and the above webViewContentHeight does not change at all.  And, of course, the UIButton stays pushed way down where it was in Portrait with a tall(er) webViewContentHeight.</p>
  
  <p>???</p>
