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 can access and make changes to it. You can instead allow anyone who has the link to access the presentation. If you don’t want others to make changes, you can set the presentation permission to view only.
Invite people to collaborate
These instructions assume that you’re signed in to your device with your Apple ID and Keynote is set up to use iCloud Drive.
Do one of the following:
If the presentation is open: Tap
. If you don’t see the button, tap Edit [icon] 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, tap Select in the top-right corner, tap the presentation (a checkmark appears), tap Share at the bottom of the screen, then tap Add People.
Tap Share Options.
Below Who Can Access, tap an option:
Only people you invite: Only people who sign in with an 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.
Anyone with the link: Anyone who has the link to the shared presentation can tap or click the link to open the presentation. To protect it with a password, tap Add Password.
If this presentation already has a password, it applies to the shared presentation as well, so you don’t need to enter a new one. If you want to change it, tap Change Password.
Below Permission, tap an option to set what others can do:
Can make changes: People can edit and print the shared presentation.
View only: People can view and print the shared presentation but not edit it.
If you set access to “Only people you invite” (in step 3), you can change individual permission settings after you share the presentation.
Tap Add People in the top-left corner.
Tap a method for sending the link.
To send the link using a service like Twitter, that account must be set up on your device. (If you already use that account on your device, then it’s set up; if not, set it up in Settings.) To use a service that’s not listed, tap Copy Link.
Type an email address or phone number for each person.
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.
Enter any other requested information, then send or post the message.
If you chose Copy Link, tap where you want to paste the link, then tap Paste.
The link appears in the body of the email, message, or post along with the presentation title—be sure not to edit or delete it.
Important: When you tap Share, a link to the presentation (which includes its title) is created on iCloud. If the title or content of the presentation is confidential, be sure to ask recipients not to forward the link to anyone else.
After you share a presentation, a checkmark appears on the Collaborate button 
to indicate the presentation is shared. To see all your shared presentations, tap Recents at the bottom of the presentation manager.
Invite more people
If you’re the owner of a shared presentation whose access is set to “Only people you invite,” you can invite more people.
Note: If the presentation access is set to “Anyone with the link,” you can’t invite new people as described in this task. Instead, simply send them the link (see the next task).
Do one of the following:
If the presentation is open: Tap Collaborate, then tap Add People at the bottom of the participant list.
If the presentation is closed: In the presentation manager or Files app, open the Keynote folder in iCloud Drive, tap Select in the top-right corner, tap the presentation (a checkmark appears), tap Share at the bottom of the screen, then tap Add People.
Tap Share Options, then tap the permission setting for the new people.
This setting affects only the new people you’re about to invite; it doesn’t change the permission of those you’ve already invited.
Tap Send Link, then tap a method for sending the link.
The link may appear in the body of the email, message, or post as a stylized graphic with the presentation title—be sure not to edit or delete it.
You can change individual permission for the new people after you send or post the link.
For details on setting permission and sending the link, see “Invite people to collaborate,” above.
Send the link to more people
If your presentation access is set to “Anyone with the link,” you can give new people access to the presentation simply by sending them the presentation link.
Note: If the presentation access is set to “Only people you invite,” you add new people by sending them an invitation to collaborate (see the task above).
Do one of the following:
If the presentation is open: Tap
.If the presentation is closed: In the presentation manager or Files app, open the Keynote folder in iCloud Drive, tap Select in the top-right corner, tap the presentation (a checkmark appears), tap Share at the bottom of the screen, then tap Add People.
Tap Send Link, then tap a method for sending the link.
Address the email, message, or post, then send or post the link.
For details on sending the link, see “Invite people to collaborate,” above.
Copy and paste the link
If you’re the owner of a shared presentation, or if you’re collaborating on a presentation whose access is set to “Anyone with the link,” you can copy the shared presentation link and paste it somewhere else. You might want to do this, for example, to save the link where you can easily access it.
If the owner limited access to only people they invite, the link only works for invited participants.
Do one of the following:
If the presentation is open: Tap
.If the presentation is closed: In the presentation manager or Files app, open the Keynote folder in iCloud Drive, tap Select in the top-right corner, tap the presentation (a checkmark appears), tap Share at the bottom of the screen, then tap Add People.
Do one of the following:
Tap Copy Link (or if you’re the owner, tap Share Options, then tap Copy Link). You see this option if the presentation was shared only by invitation.
Tap Send Link, then tap Copy Link. You see this option if the presentation was shared with anyone who has the link.
Tap where you want to paste the link, then tap Paste.
Tip: You can also post the shared link on a website that supports embedded Keynote presentations (such as Medium or WordPress) so that viewers can navigate through the presentation in a player on the website. See Post your presentation in a blog with Keynote on iPad.
If the presentation is protected by a password, for security reasons don’t send the password with the link.
