upload files via iPad

问题:

One of our users just notified us that our web application works very well through Safari on the iPad (or whatever the default browser is -- I assume Safari). The only thing that doesn't work is the file upload part.

Our web application enables our users to attach files in various parts of the system.

I was thinking about this. The iPhone takes pictures, but doesn't really give me the ability to upload them via a standard web interface (where you click a button, choose a file, upload the file, etc).

Is this even possible? Or is the only way to upload files from an iPhone/iPad via a custom app written for the device?

Is there a way to upload a file on an iPad via the web browser?

回答1:

As far as I know the iOS doesn't expose a file system to the user, so it wouldn't really make sense for it to be possible to upload files via a web interface. Most of the apps that do exist, sync files through iTunes or something similar.

One approach I've also seen used was for the iOS device to act as a fileserver and enabling you to download files that way. This is how iFile works.

In short, to my knowledge it isn't possible.

This ability was shown during the 2012 WWDC keynote. I believe details are under NDA unless you're a registered iOS developer. Take a look at the iOS 6 beta documentation.

This post has a photo of the keynote slide highlighting "photo upload" as a new feature. http://www.anandtech.com/show/5987/ios-6-safari

Mobile safari on iPhone/iPad does not allow file uploads (the file upload button/widget is displayed disabled), however you can re-enable that feature by calling a third-party uploader app from your web app/site.

Have a look at http://www.aurigma.com/iphone/ for such an uploader app.

There are some replacement web browsers you can get from the app store that allow you to upload. You use them instead of Safari. One example is iCab Mobile.

There is now way via HTML5 on iOS6+ devices.

<input type="file" capture="camera" accept="image/*" id="cameraInput" name="cameraInput">

I've tested it in Safari on an ipad with iOS9.
