title: How do I upload a file from iOS to my website?
body: <p>I have a website that receives files from the user, using the "Choose file" interface for the OS they're on. This worked for me on Windows, Mac and Linux, but not on iOS. When I click the button that should load the interface, nothing happens. I guess I have to do it in a specific way for iOS. We're using the ZK framework to develop the website, but if you know how to do the upload in some other way, please tell me.</p>
