You can add as many cloud accounts as you’d like. For example, you could add cloud accounts for personal- or work-use, a group-accessible account for your UX team...pretty much whatever you need. The only real limitation is the amount of available storage space on each device.

This chapter opens up the clouds by showing you how to create and connect to Omni Sync Server via OmniGraffle’s built-in OmniPresence. From there, you’ll learn how to connect to other Cloud Storage Providers using a new service that allows you to connect to iCloud Drive, Box, Dropbox, and more.

Whenever you make a change to a file, the file in the cloud is updated when OmniGraffle performs its next sync operation. Of course, this assumes your iOS device is connected to the Internet. And if you aren’t, those changes will sync the next time you are.

Another benefit of storing files in the cloud is that, if you lose or misplace your iOS device, your documents are safe and secure on your cloud provider’s server. All you need to do to access your files is log in to your cloud account, change your password, sync the files with your new iPhone or iPad, and then you’re back in business.

And while most cloud services—including Omni Sync Server—maintain backups, you shouldn’t trust that your cloud provider will be able to help you out in a pinch. Just because you are storing your files in the cloud doesn’t absolve you from backing up your files—you totally should maintain backups of all your stuff! Be sure to regularly backup your iOS device (either to iCloud or to your Mac), and maintain a regular backup schedule for your Mac, too.

• Omni Sync Server, which is a bank of servers we maintain so you can store files in the cloud. OmniPresence is built into our iOS apps (there’s a desktop app for your Mac, too), so there’s nothing additional to download. All you need to do is sign up for a free Omni Sync Server account.
• WebDAV Connectivity is a hook we provide in OmniPresence so users who wish to maintain their own server can store and sync files. You can connect to your own WebDAV server, a third-party service that you trust, or you can even set up a WebDAV service on your local network using WebDAVNav Server.

Now that you know your choice of paths for using OmniPresence, let’s show you how to set them up in OmniGraffle.

sync.omnigroup.com

Just go to that page, enter your email address, and click Sign Up. We’ll send you an email with instructions on how to set up your Omni Sync Server account.

When everything is ready to go with your Omni Sync Server account, return to the Locations screen in OmniGraffle and then follow along.

1. To start syncing to Omni Sync Server, start on the Locations screen and tap Add OmniPresence Account.

   

2. Next, choose the type of cloud account you would like to use; you can choose between Add Omni Sync Server Account or Add WebDAV Server. The difference between the two is that we host and maintain Omni Sync Server, whereas you would need to find a third-party WebDAV server (or host your own) and entrust them to maintain the server.

   Tap Add Omni Sync Server Account.

   

3. On the Account Info screen that appears:

   1. Enter your Account Name
   2. Enter the Password for your account
   3. Optionally, enter a Nickname to be used as the name for your synced folder
   4. Tap Save to authenticate with Omni Sync Server

   

The next message you’ll see is Testing Server for Compatibility along with a progress bar. If everything checks out okay, OmniGraffle lets you know that it has successfully connected to Omni Sync Server.

When your credentials have authenticated, you’re taken back to OmniGraffle’s Locations screen where you’ll see a new folder for your synced files.

To access the files within a document folder, just tap the folder of your choice, and then tap the file you would like to work on.

1. Enter the URL for the Location of your WebDAV Server
2. Enter your Account Name
3. Enter the Password for your account
4. Optionally, enter a Nickname to be used as the name for your synced folder
5. Tap Save to authenticate with the WebDAV server

As with connecting to Omni Sync Server, OmniGraffle informs you that it is Testing Server for Compatibility, and displays the Connected screen when it has connected to the WebDAV server successfully.

Keep an eye on this icon to monitor OmniPresence’s sync status:

• — denotes that OmniPresence is active and ready to sync files to the server.
• — denotes that a sync is currently in progress.
• — denotes that your iOS device does not have access to an active Wi-Fi or cellular network.
• — denotes that there was an error when trying to sync your files. You may see this icon if someone else is working on the same file, or if a connection cannot be made to the sync server you are using. Try tapping the OmniPresence icon again and if you get the same error icon, please contact our Support Humans for assistance.

OmniPresence checks in with your active sync servers every minute or so, and saves any updates you’ve made to the server. OmniPresence also saves a version of your file to the server whenever you close a file or switch from OmniGraffle to another app on your device. Alternately, you can tap the OmniPresence icon to force an update to the server at any time.

1. Tap Use Cloud Storage Providers

   

2. Tap the switch next to Use Cloud Storage Providers to turn on the service

   

The switch turns green to let you know that the Cloud Storage Providers service has been turned on. Tap Settings and then Done to close the windows and return to the Local Documents folder.

If you tap Locations in the toolbar, you’re taken back to the Locations screen, where you’ll now see an Other Documents folder; this is where you access files you store in the cloud.

With Cloud Storage Providers turned on in OmniGraffle, there’s one more switch you’ll need to flip if you want to use iCloud Drive from Apple. Let’s do that next.

In the list of apps that use iCloud Drive, make sure that the switch next to OmniGraffle is also On. This allows OmniGraffle to open and save files stored on iCloud Drive.

On your iOS device, open Settings, and then choose iCloud ▸ iCloud Drive, and make sure that iCloud Drive and Show on Home Screen are switched on.

The iCloud Drive app lets you see, organize, and remove files that you have saved to iCloud. For example, you can create a separate folders for storing the things you create with OmniGraffle or the outlines you create with OmniOutliner.

When working with files stored on iCloud Drive, you can add files to OmniGraffle’s Other Documents folder, or you can copy them from iCloud Drive into the Local Documents folder from the iCloud Drive app. See Opening and Working on Files in the Cloud for instructions on how to add files stored in the cloud to the Other Documents folder. Or, to work with files stored on iCloud Drive, follow these steps:

1. Tap iCloud Drive to open the app on your iOS device.
2. Locate the OmniGraffle file you would like to open:

   

3. When you tap to select the file, iCloud Drive offers the option to download it to your device. Tap Download to proceed.

   

4. When the file has finished downloading, you will see a screen similar to the following:

   

If you switch to OmniGraffle at this point, the file you tapped won’t be ready for use. Instead, the file has only been downloaded from Apple’s servers to the iCloud Drive app on your device. At the bottom of this screen, you’ll see the following three options:

• Tap to open or send the file to another app.
• Tap to delete the file from iCloud Drive. Be careful here, as this permanently removes the file from iCloud Drive. If you don’t have a backup of the file and you select this, the file won’t be recoverable.
• Tap to move the file to another folder on iCloud Drive.

Since you want to work on the file in OmniOutliner, tap and then tap Copy to OmniGraffle. This does two things: first, it saves a copy of the file in OmniGraffle’s Local Documents folder; and the file automatically opens in OmniOutliner.

This is very different from adding files to the Other Documents folder from the cloud. When you download a copy of the file from iCloud using the iCloud Drive app, you have just that—a copy. The file still resides on iCloud Drive, but the file you copied to your iOS device is no longer connected to the file on iCloud Drive. This means that any changes you make to the file copied to Local Documents won’t be saved back up to the cloud. Be careful.

Finally, if you tap Documents in OmniGraffle when you have finished working on the file, you will see Back to iCloud Drive along the top of the screen on the left. If you tap that, you are taken out of OmniGraffle and back to the iCloud Drive app on your device.

To push your changes you made to the copied file in Local Documents back up to iCloud Drive, do the following:

1. Tap Select.
2. Tap to select the file you want to move to iCloud Drive; a blue border is placed around the selected file.
3. At the top of the screen, tap , and then tap Export to... in the menu that opens.
4. Choose the file format to export; for example, OmniGraffle (which produces a file that ends with a .graffle file extension).
5. Choose the the location. By default, the export window opens to iCloud Drive; that’s mighty convenient.
6. Tap Done.

The file still resides in the Local Documents folder, but now you can safely delete that file from your device with the knowledge that your changes have been stored on iCloud Drive.

Let’s assume that you have a file in your Local Documents folder that you’d like to store on Dropbox instead. Here’s what you need to do:

1. In the toolbar, tap Select. This lets you choose files in a folder so you can do something with them.
2. Locate the file that you want to move to Dropbox, and then tap to select it. When you select the file, a blue border is placed around the file icon to indicate that it’s ready for action.

   

3. In the toolbar, tap to open the Sharing menu.

   

4. In the Sharing menu, tap Export to....
5. Choose the file format that you would like to save the document to. You can choose from OmniGraffle, PDF, PNG, or OmniOutliner, depending on your needs.

   

6. Tap Locations to open the Cloud Storage Providers’ menu, and then tap to choose Dropbox as the storage location.

   

7. After you choose the cloud service, the window changes to show you the files and folders for your account on that service. Choose a Save Location and then tap Save to... at the bottom of the window.

   

When you export a file to one of the Cloud Storage Providers, the file you exported also remains in its original location. So, if you exported a file from Local Documents to Dropbox, that file is now in two places. If you want to continue working on the file while it’s stored on Dropbox, you might consider deleting the copy stored in Local Documents just to avoid confusion.

For example, to open a file that resides on iCloud Drive, follow these steps:

1. On the Locations screen, tap Other Documents.

   

2. In the toolbar, tap to add a document stored on iCloud Drive (or another service) to the Other Documents folder.

   By default, the file chooser reveals the files available on iCloud Drive. (If the file is on another cloud service, tap Locations, and then tap to choose your cloud provider.)

   

3. Locate the file you want to work on, and then tap to choose and add the file to the Other Documents folder on your device.

   

4. Finally, tap to open the file in OmniGraffle.

When you Open a file that’s stored on iCloud Drive, the file remains on iCloud Drive while you are making changes. When you close the file (by tapping Documents in the toolbar), the changes are saved to the file on iCloud Drive.

• Do you leave them in the Other Documents folder?
• Or do you remove them from your device?

There’s nothing wrong with leaving files there, especially if you have more work to do to your diagram. Files that you add to the Other Documents folder are shadow files of the original in the cloud. The two are linked for the purpose of synchronizing the changes you make, with the file in the cloud as the “one true source”.

Optionally, you can remove the file from the Other Documents folder. If you need to work on the file again, you can always add it back to your device. Removing the file from the Other Documents folder does not delete the file from iCloud Drive—your file is safe and secure in the cloud—it just removes the file from your device.

To delete a file from the Other Documents folder:

1. In the toolbar, tap Select.
2. Tap to choose the file (or files) you’d like to delete.
3. Tap in the toolbar, and then tap Remove Document.

Files you remove from the Other Documents folder just disappear; they are not moved into a Trash folder. This is because files added to the Other Documents folder are just shadow files (for lack of a better term) of the actual files stored in the cloud.

A quicker way to do this is to swipe left across the account name to bring up the Delete button. If you change your mind before deleting the account, tap Done and the Delete button goes away.
