iOS Question Problem SetField Invitees

[mayahandayani]

Hello!
I have problem when I want to set some emails as invitees using EventKit (https://developer.apple.com/documentation/eventkit/ekparticipant?language=objc).
This is my code :

Dim ev As CalendarEvent = store.CreateEvent
Dim newEvent As NativeObject = ev

Dim attendee As NativeObject
attendee.Initialize("EKParticipant")
Dim url As NativeObject
url.Initialize("NSURL")
url = url.RunMethod("URLWithString:", Array("mailto:" & "[email protected]"))
Dim attend As List
attend.Initialize
attend.Add(url)
attendee.SetField("URL", attend)       
newEvent.SetField("attendees", Array(attendee))

and I've got error like this

[<EKParticipant 0x1f64fca80> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key URL.

what's wrong?
thanks

Hi Erel!

Please don't do it. All threads are open to all forum members.

Please post the link to the property documentation that you want to set. If it is a field that you see with the debugger and it isn't documented then you will not be able to call it.

EKParticipant | Apple Developer Documentation

A class that represents person, group, or room invited to a calendar event.

I'm using EKParticipant but I have no idea how to set the email as invitees. Or what the property I can use and how to set it?

Thanks

Looks like you are using the wrong object.

from the documentation

Overview​

Do not create EKParticipant objects directly. Instead, use the property attendees on EKCalendarItem to return an array of EKParticipant objects.

EventKit cannot add participants to an event nor change participant information. Use the properties in this class to get information about a participant.

A participant can be a person, group, room, or other resource.

I know, I already use EkCalendarItem when I want to get information about attendees.
But my question is, how to set the email as invitees when I save / update an event? Or I can't do that?

Thanks

I don't understand what you mean by "set the email as invitees"

I don't understand what you mean by "set the email as invitees"

like this on iPhone Calendar

StackOverflow seems to have a solution.

Modifying EKParticipants (attendees) in EventKit like Sunrise

My goal is to add some invitees to an EKEvent. I've looked into other questions like this, such as this one, but all say that it is essentially impossible to add EKParticipants to an EKEvent

like this?

Dim attendees As List

Dim attendee As NativeObject
attendee.Initialize("EKAttendee")
attendee.SetField("emailAddress", "[email protected]")
attendees.Add(attendee)
newEvent.SetField("attendees", attendees)

but still same error
