Problems displaying PDF in iFrame on Mobile Safari

I found a new solution. As of iOS 8, mobile Safari renders the PDF as an image within an HTML document inside the frame. You can then adjust the width after the PDF loads:

<iframe id="theFrame" src="https://stackoverflow.com/questions/15480804/some.pdf" style="height:1000px; width:100%;"></iframe>
<script>
document.getElementById("theFrame").contentWindow.onload = function() {
    this.document.getElementsByTagName("img")[0].style.width="100%";
};
</script>
