title: UIWebview default zoom level
body: <p>In my app, I use UIWebviews to display some one page PDFs, I've noticed that in iOS5 the default zoom level is to show the entire document where as in 4.3 the document was opened zoomed in.</p>
  
  <p>Is it possible to programmatically set the zoom level on the UIWebview?</p>
  
  <p>*I've also tried a QLPreviewController and am noticing this same default zoomed out behaviour</p>
