Invite others to collaborate in Pages on iPhone
You can invite others to work with you on a document in real time by sending them a link to it. Everyone working on the document can see changes as they’re made.
By default, only the people you invite to collaborate on the document and who sign in using their 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 document.
After you share a document, you can invite more people to join the document 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 document is protected by a password, for security reasons don’t send the password with the link.
Invite people to collaborate
To invite others to collaborate on a document, make sure that you’re signed in with your Apple ID, Pages is set up to use iCloud Drive, and the document you want to share is stored in iCloud Drive.
Do one of the following:
If the document is open: Tap
in the toolbar. If you don’t see the button, tap 
at the top of the screen, then tap .If the document is closed: In the document manager or Files app, open the Pages folder in iCloud Drive, tap
in the top-right corner, then tap Select. Tap the document (a checkmark appears), then tap 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 document, tap the disclosure arrow below Collaborate, then choose an option under Who Can Access (if you don’t see this option make sure the document is stored in iCloud):
Only invited people: Only people you invite who sign in with their Apple ID can open the document. 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 document.
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 document can tap or click the link to open the document.
To change who can make changes to the document, tap an option under Permissions:
Can make changes: People can edit, print, and download the shared document.
View only: People can view, print, and download the shared document, 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 Done.
Tap a method for sending the invitation to collaborate (if the document 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 link, then tap Paste.
Important: The link to the document that’s created when you invite collaborators includes the document’s title. If the title or content of the document is confidential, be sure to ask recipients not to forward the link to anyone else.
After you share a document, a checkmark appears on the Collaboration button 
to indicate the document is shared.
Invite more people to sign in to the document
If you’re the owner of a document whose access is set to “Only invited people,” or if the owner of a shared document gives you permission to add people, you can invite more people to join the document using their Apple ID.
Note: If the document 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).

Note: The link may appear in the body of the message as a stylized graphic with the document title—be sure not to edit or delete it.
Any participant can copy a link to a document 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)
