Share files in iCloud Drive on iPod touch
After you set up iCloud Drive, you can use the Files app 
to invite others to view and edit your files. When you share a file in iCloud Drive, you send a link to the item, not a copy. When you make changes to a shared file, others see your changes. If you allow people to make changes, the item is updated with everyone’s changes automatically.
Files shared in iCloud Drive have these important characteristics:
The link to a shared file includes its name. If the name or content is confidential, be sure to ask recipients not to forward the link to anyone else.
If you move a shared file to another folder or location, the link no longer works, and people lose access to the item.
Depending on the app, users might need to reopen a file or tap the original link to see the latest changes.
Invite others to share a file
If you own a file in iCloud Drive, you can invite others to view or change its contents.
You can restrict access to a file so that only those people you invite can open it. To authenticate their identities, the invitees must be signed in with their Apple IDs.
You can also share a file with people who don’t have Apple IDs. However, when you share with someone who doesn’t have an Apple ID, anyone else with the link to the file also has access to the item.
You can allow the contents of a file to be changed, or you can restrict access so that the contents can only be viewed.
Touch and hold the file.
Tap Share
, then tap Add People.Do one of the following:
Allow only invitees to view and edit the contents: Choose a method—such as Messages or Mail—for sending a link to the file. To open the item, the people you invite must be signed in with their Apple IDs.
Allow only invitees to view the contents: Tap Share Options, tap “View only,” tap Add People (at the top of the screen), then choose a method—such as Messages or Mail—for sending the link. To open the item, the people you invite must be signed in with their Apple IDs.
Allow anyone with the link to view and edit the contents: Tap Share Options, tap “Anyone with the link,” tap “Can make changes,” tap Add People (at the top of the screen), then choose a method for sending the link.

Touch and hold the file.
Tap Share
, tap Show People, then tap Share Options.Change either or both of the options.
When you change the access option, the original link no longer works for anyone, and only people who receive a new invitation from you can open the file.
When you change the permission option, everyone who has the file open when you change the permission sees an alert. New settings take effect when they dismiss the alert.
Change the permission or remove access for a single invitee
If you’re the owner of a shared file and its access is set to “Only people you invite,” you can change the permission for an individual without affecting the permission of others. You can also remove the individual’s access.

Anyone who has a file open when you stop sharing it sees an alert. The item closes when the alert is dismissed, the file is removed from the invitee’s iCloud Drive, and the link no longer works. If you later share the item again and set the access to “Anyone with the link,” the original link works. If the access is set to “Only people you invite,” the original link works again only for people you reinvite to share the item.
