Respond to Invitations on Your iPad Calendar
In the Calendar program on your iPad, the Invitations button, which you'll find next to the Calendars button in the upper-left corner of the screen, enables you to see and respond to invitations you’ve received for events. You can also send an invitation when you create a calendar event.
If you don’t see an Invitations button, tap Settings→Mail, Contacts, Calendars→New Invitation Alerts to make its blue On button appear.
You need an Internet connection to respond to an invitation. The following steps walk you through the process:
Tap the Invitations button to view your pending invitations.
The Invitations button is next to the Calendars button in the upper-left corner of the screen.
Tap any of the items in the list to see more details.
For example, suppose that a meeting invitation arrives from your boss. You can see who else is attending the shindig (by tapping Invitees); send them an e-mail, if need be; and check scheduling conflicts, among other options.
Tap Accept to let the meeting organizer know you’re attending; tap Decline if you have something better to do (and aren’t worried about upsetting the person who signs your paycheck); or tap Maybe if you’re waiting for a better offer.
You can also import events from an e-mail. Open the message and tap the calendar file, which adheres to the .ics standard. When the events show up, tap Add All, choose the calendar you want to add it to, and then tap Done.
