With iOS 7 it´s now possible to export vCards the normal way.
(Take a look here: https://stackoverflow.com/a/11405271/2861693)
My header hence looks like this
case "ios_seven":
header("Content-Type: text/x-vcard; charset=utf-8");
header("Content-Disposition: attachment; filename=\".".utf8_decode($this->contact->getLastName())."..vcf\";");
echo $vcard;
break;
and works really great when opening the webapp with safari. But as soon as I call it with an inappbrowser (which is a common case because the link is retrieved by scanning a qr-code), it fails loading...
Somebody got an idea for an inappbrowser-compatible header for exporting vCards?
