title: UIWebView memory leak
body: <p>I have an iPad app (IOS 4.3 &amp; 5.0) that is creating a UIView with at least 2 subviews every time the user pages forward or backward. The 2 subviews are UIWebView objects.</p>
  
  <p>On every relevant swipe the old UIWebViews are removed and deallocated  properly (removeFromSuperview then stopLoading and set delegate to nil) and the parent UIView is deallocated. I can confirm that both parent UIView and the 2 child UIWebViews are absolutely gone.</p>
  
  <p>I can see the retain count on the webviews as they are being removed and I am quite sure that they are indeed removed every time.
  However my memory allocation continues to increase on every swipe by ~200-350k . No leaks in instrument but I can see the memory usage going up slowly.
  On iPad 1 the app eventually (within 6-10 minutes of moderate usage) receives multiple memory warnings and is terminated. LowMemory crash log...etc is generated.</p>
  
  <p>We use stringByEvaluatingJavaScriptFromString and loadRequest to populate the Webviews. Memory usage creeps up even when nothing is injected or loaded into the webViews.</p>
  
  <p>Is anybody experiencing this kind of behavior with UIWebViews ? Has anyone dealt with this successfully ?</p>
  
  <p>Thoughs, comments &amp; answers would be greatly appreciated.</p>
