Copy presentations between a WebDAV server and iPhone or iPad
Open Keynote on your iPhone or iPad.
Do one of the following to navigate to Locations in the presentation manager:
In an open presentation, tap Presentations or in the top-left corner of the screen. If Locations doesn’t appear in the top-left corner of the next screen, tap again until you see Locations.
If no presentation is open and you don’t see a Locations list, tap Browse at the bottom of the screen, then tap Locations in the top-left corner of the screen (if necessary).
Tap WebDAV in the Locations list, then tap Connect to WebDAV Server.
If you don’t see WebDAV below Locations, tap at the top of Locations, tap Edit, turn WebDAV on, then tap Done.
Type the server address and your user name and password, then tap Sign In.
After you sign in to your WebDAV server, you can open and edit presentations on the server without signing in again. You remain signed in to the server until you tap next to WebDAV in the Locations list.
Do one of the following:
Copy a presentation from the server: Tap the presentation on the server. When the transfer is complete, the presentation appears in the presentation manager. Tap the presentation to open it on your device.
Copy a presentation to the server: With the presentation manager in browse view, tap Select in the top-right corner, tap the presentation, then tap Move at the bottom of the screen. Tap WebDAV, then tap Copy in the top-right corner.
Open and edit a presentation: Tap the presentation. When the transfer is complete, the presentation opens and any edits you make are synced back to the server.
