Invite others to collaborate in Keynote on iPad
You can invite others to work with you on a presentation in real time by sending them a link to it. Everyone working on the presentation can see changes as they’re made.
By default, only the people you invite to collaborate on the presentation and who sign in using an Apple ID can open and make changes to it. However, you can change the access privileges so that anyone with the link can open it (without an Apple ID), or change the editing privileges so people can view, but not edit, the presentation.
After you share a presentation, you can invite more people to join the presentation at any time. How you invite others depends on which access privilege is chosen (that is, whether invitees need to sign in with an Apple ID or not).
Tip: If the presentation is protected by a password, for security reasons don’t send the password with the link.
Participants can also present a shared slideshow with you. To learn more about multi-presenter slideshows, see Play a slideshow with multiple presenters.
Invite people to collaborate
To invite others to collaborate on a presentation, make sure you’re signed in with your Apple ID, you’ve set up Keynote to use iCloud Drive, and the presentation you want to share is stored in iCloud Drive.
Do one of the following:
If the presentation is open: Tap
in the toolbar. If you don’t see the button, tap 
at the top of the screen, then tap .If the presentation is closed: In the presentation manager or Files app, open the Keynote folder in iCloud Drive, then tap Select in the top-right corner. Tap the presentation (a tick appears), then tap Share at the bottom of the screen.
If Collaborate isn’t showing in the pop-up menu at the top, tap the pop-up menu, then tap Collaborate.
To change who can access the presentation, tap the disclosure arrow below Collaborate, then choose an option under Who Can Access (if you can’t see this option, make sure the presentation is stored in iCloud):
Only invited people: Only people you invite who sign in with their Apple ID can open the presentation. People don’t need to have an Apple ID before you invite them; however, they need to create one before they can open your shared presentation.
If you invite someone using an email address or phone number that isn’t associated with their Apple ID, they won’t be able to accept the invitation until they add the email address or phone number to their Apple ID. Instructions are provided when they tap or click the link in the invitation.
Anyone with the link: Anyone who has the link to the shared presentation can tap or click the link to open the presentation.
To change who can make changes to the presentation, tap an option under Permissions:
Can make changes: People can edit, print and download the shared presentation.
View only: People can view, print and download the shared presentation, but not edit it.
Note: If you set access to “Only invited people” (in the previous step), you can change individual permission settings after you share it.
If you don’t want all participants to be able to invite others, turn off “Allow others to invite”.
To return to the Collaborate controls, tap Back.
Tap a method for sending the invitation to collaborate (if the presentation isn’t stored in iCloud Drive, you’re prompted to move it there):
Mail or Messages: Type an email address or phone number for each recipient, add a note if you want, then tap Send. A link to the file is sent to each recipient.
Invite with Link: Copy the file’s link, so you can send it or post it using any internet service that’s already set up on your device. Type an email address or phone number for each recipient, then tap Share Link. Open the app you want to use to share the link, tap where you want to paste it, then tap Paste.
Important: The link to the presentation that’s created when you invite collaborators includes the presentation’s title. If the title or content of the presentation is confidential, make sure you ask recipients not to forward the link to anyone else.
After you share a presentation, a tick appears on the Collaboration button 
to indicate the presentation is shared.
Invite more people to sign in to the presentation
If you’re the owner of a presentation whose access is set to “Only invited people”, or if the owner of a shared presentation gives you permission to add people, you can invite more people to join the presentation using their Apple ID.
Note: If the presentation access is set to “Anyone with the link”, follow the instructions in the next task Send the link to more people (no Apple ID required).
Do one of the following:
If the presentation is open: Tap

Tap Share With More People, then choose a method for sending the invitation to collaborate:
Mail or Messages: Type an email address or phone number for each recipient, add a note if you want, then tap Send. A link to the file is sent to each recipient.
Invite with Link: Copy the file’s link, so you can send it or post it using any internet service that’s already set up on your device.

Important: The link to the presentation that’s created when you invite collaborators includes the presentation’s title. If the title or content of the presentation is confidential, make sure you ask recipients not to forward the link to anyone else.
Note: The link may appear in the body of the message as a stylised graphic with the presentation title — make sure you don’t edit or delete it.
Any participant can copy a link to a presentation and paste it somewhere else — for example, to save the link where they can easily access it. If the owner limited access to people they invite, the link only works for invited participants.
You can change the sharing settings for the new people after you send the link.
Send the link to more people (no Apple ID required)
If your presentation’s access is set to “Anyone with the link”, you can invite more people to collaborate on the presentation by sending them a link that doesn’t require an Apple ID to view the presentation.
