iAnnotate supports integration with WebDAV. A connection between iAnnotate and your WebDAV account allows you to browse your entire WebDAV folder structure from the iAnnotate Library, select and download documents and folders, and upload documents back to WebDAV after you have marked them up. However, it does not allow you to actually modify or reorganize how your WebDAV is set up, with the exception of moving or copying documents from iAnnotate to WebDAV.
Connecting to WebDAV
Navigate to your Document Library (by tapping the Library button in the upper left) and tap Connections in the Library navigation panel. Tap "Add WebDAV" and enter a description. Enter the base URL for the WebDAV host, your username (typically your email address), and your password. Then tap "Set Up Connection." Choose "Read Only" if you want to use the connection to import files, but wish to disable syncing annotated files back to your WebDAV server. With this option turned on, your annotations will only be saved to your iPad and not backed up to WebDAV.
Downloading and Managing Files
The connection between WebDAV and iAnnotate lets you import documents in PDF, DOC, GIF, JPEG, PNG, or PPT format. To download a document, simply tap on it, or tap and hold then select Download from the popup menu.
Upon modifying a document from within the WebDAV connection, the sync icon in the upper-right of your screen will turn red to indicate there are un-synced changes. Tap the sync icon to upload the changes back to WebDAV immediately; changes are uploaded automatically when you close the document tab.
Deleting any document from iAnnotate does not also delete it from your remote WebDAV server. The document would still exist in WebDAV, in its most recently modified and synced version.
You can move local documents into your WebDAV account from iAnnotate. To do so, tap and hold a document in the iAnnotate PDF Library, then tap Move and select WebDAV from the list of target folder options. Alternatively, you can select multiple documents using the selection circles next to them, then tap "Move" in the Actions accordion at the left of the Library. However, you can not move whole folders into your WebDAV account.
You can also move a document from your WebDAV into local storage on your iPad. To do so, tap and hold a document in your WebDAV folder within the iAnnotate PDF Library, then tap "Copy" and select Local Files from the list of target folder options. This creates a copy of your document that isn’t synced to your WebDAV.
