title: Can you download a passbook coupon from a UIWebView inside an IOS app?
body: <p>Is it possible to download and add a passbook from within a webview without modifying the app to support the new MIME type or unknown MIME types like Sparrow did?</p>
  
  <p>I have a news ios app with a webview. In the webview I display the news items and a banner. When you click the banner I want to open a url to a .pkpass file and add it to my passbook. Instead I get a FrameLoadInterrupted error and nothing visible happens.
  If I open the url from safari this works fine, chrome, since earlier this week (version 23) also opens the url like intended.</p>
  
  <p>Is this some weird strategy from Apple maybe? not allowing this MIME type to properly open from a webview?</p>
