EXECUTIVE SUMMARY
I want users of my application to be able to accept / decline an invitation to an event on their calendar. To do this, I try to open the event using the EventKitUI components and allow the user to update the event without leaving my application.
The problem is that it resets every time I assign an EKEvent to an EKEventViewController.
DETAILED DESCRIPTION
WHAT I WANT:
To display a similar view similar to that in the native iOS calendar, it should look something like this:
WHAT I HAVE:
import UIKit
import EventKitUI
class CalendarViewController: UIViewController, EKEventViewDelegate, EKEventEditViewDelegate {
var meetingID = "id"
override func viewDidLoad() {
super.viewDidLoad()
self.showInvite(meeting: meetingID)
}
func showInvite(meeting: Meeting){
let evc = EKEventViewController()
var event = EKEvent(eventStore: MeetingsFetcher.eventStoreClass)
event = MeetingsFetcher.eventStoreClass.event(withIdentifier: meetingID)!
evc.delegate = self
evc.event = event
evc.allowsEditing = true
evc.allowsCalendarPreview = true
self.screen.present(evc, animated: true, completion: nil)
}
func eventViewController(_ controller: EKEventViewController, didCompleteWith action: EKEventViewAction) {
controller.dismiss(animated: true, completion: nil)
}
}
:
, EKEvent evc.event, - . , .
evc.event = event
, , EKEventEditViewController(), .
, , , :
func showEditEvent(meeting: Meeting){
let evc = EKEventEditViewController()
evc.eventStore = MeetingsFetcher.eventStoreClass
var event = EKEvent(eventStore: MeetingsFetcher.eventStoreClass)
event = MeetingsFetcher.eventStoreClass.event(withIdentifier: meeting.UUID!)!
evc.event = event
evc.editViewDelegate = self
self.screen.present(evc, animated: true, completion: nil)
}
func eventEditViewController(_ controller: EKEventEditViewController, didCompleteWith action: EKEventEditViewAction) {
controller.dismiss(animated: true, completion: nil)
}
