Open native app from webpage, mobile safari "invalid address" warnings be suppressed when the app is not installed.

openApp.js

/*
  Open native app through iframe so that mobile safari "invalid address" warnings be suppressed when the app is not installed.
   
    * `window.location=url` will not open native app in the iframe of android chrome
    * Android will go to the next page even if the url scheme is not supported
*/
  function openApp (url) {
    if (window.chrome && navigator.userAgent.search(/\bChrome\b/)!=-1) {
      window.location = url;
    } else {
      openAppByFrame(url);
    }
  }


  /*
    # Problems
    * `window.open` will open tab selection view of iOS Safari
  */
  function openAppByFrame(url) {
    var frm = getOpenAppProxyFrame();
    var src = '\<script\>window.location="' + url + '";\</script\>';
    frm.contentDocument.write(src);
  }

  var _openAppProxyFrame;

This stopped working in iOS9, has something changed or is there a fix to make it work with iOS 9? thank you!

I'm keen on a fix for iOS9 too!

iOS 9 fails 👎

It does fail on iOS 9. I fail to find a solution yet.

Doesn't work on IOS 9, i love f**n apple

Apple did this on purpose to force Universal Links. Safari...and Apple to a large part....is the new IE.
That being said, the uri scheme still works....I improved upon the best known JS technique to manage uri scheme deep links (similar to above):
