title: How to disable UIWebView resize content when resize the UIWebView frame
body: <p>I have to resize the UIWebView.
  However the procedure turns to be very slow when the content in the UIWebView is complex.
  The UIWebView resize its content to fit the new size.
  I want to disable the resize function to speed up the procedure.</p>
  
  <p>The scalesPageToFit property doesn't work after the content is loaded.  It could only affect the loading progress.</p>
  
  <p>I found the UIWebView will not resize content after user manually scale the page.
  Is that mean there is some trick to disable the resize?</p>
