Have you tried using doc.output('dataurlnewwindow')?

If that doesn't work, you could make a new route like /pdf/download?data=base64data... and response the pdf there with Content-Type: application/pdf and based on the given parameter data. Be sure to avoid possible security issues, so that no other one can provide pdfs with your url.

Got a solution!! Create a html file (eg pdf.html) and add

<!DOCTYPE html><html>
<head>
    <title></title>
</head>
<body>
<script>
    document.location.href = document.location.hash.substr(1);
</script>
</body>
</html>

Create a link

<a class="btn btn-default" id="pdfData" ng-show="isMobile && pdfReady" ref="app/views/pdf.html" target="xxx">
Download PDF
</a>

After you "rendered" your pdf get the datauristring and add it to your link as hash.

var pdfData = doc.output('datauristring');
var element = document.getElementById('pdfData');
element.href = "app/views/pdf.html#" + pdfData;
element.target = "xxx";
$scope.pdfReady = true; // show download link

And now if the user clicks the download link a new window is opened in safari and the pdf get shown
