Apple has just released a new update to its iOS app that inserts a “save to Drop” option in the sharing pane for certain types of files.
This new development has made Dropbox a third-party app that work with Apple's sharing system.
It’s easy; just tap on a photo from within your photo library, select “Save to Dropbox” and instantly have uploaded on your Dropbox account.
This functionality will similarly apply to all sorts of file types, including audio files, PDF documents and more.
Version 3.7 of Dropbox, available now on the App Store, adds an action extension that lets you copy any file that can be shared with iOS’ native share menu directly to your Dropbox account.
The extension is fairly basic: you can save to your root Dropbox folder and navigate sub-folders; when uploading, a modal dialog will show a progress bar, which will be automatically dismissed when the upload is done.
