Programmatically show EKEventEditViewController in EKEventViewController

Question

I am creating a new EKEventViewController with a event and display it afterwards

 let ekEventViewController = EKEventViewController(nibName: nil, bundle: nil)
 ekEventViewController.delegate = self
 ekEventViewController.allowsEditing = true
 ekEventViewController.event = event

 setViewController(ekEventViewController)

In setViewController I'm adding the new controller as a childViewController and the new controller's view as a subview. Now I would like to call the "EDIT" action immediately after presenting the EKEventViewController. I did not subclass anything, I just want to go to editing automatically using the EKEventEditingViewController.

So far I've tried several methods related to "editing".

I also tried to invoke the editButtonItem's Selector, but no success...

ekEventViewController.perform(ekEventViewController.editButtonItem.action!

Is there a way to accomplish this without subclassing? I was even thinking about reflection but couldn't figure it out...

Thanks in advance!

Once you create your edit view controller, you just need to present it. Make sure you've defined your callbacks so you react appropriately when it dismisses itself - depending upon the action the user took (cancel, delete, add, modify):

   override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

        let sourceArray = originalEventsList

        let eventViewController: EKEventEditViewController = EKEventEditViewController()
        eventViewController.event = sourceArray[indexPath.row]
        eventViewController.eventStore = self.eventStore
        eventViewController.editViewDelegate = self
        self.presentViewController(eventViewController, animated:true, completion:nil)
    }

Thank you for your answer. You were right, I didn't think about presenting this controller directly since I wanted the usual EKEventViewController being displayed after editing has finished, but it's fine this way for me. – emmics Aug 02 '17 at 15:18
Did upvote and it helped me a step, but unfortunately it's not the actual solution for my problem since I was trying to put it in a ViewController which is not full-screen, if you understand... – emmics Aug 02 '17 at 15:26
Of course. I upvoted your question. Happy you're making progress. That's why we're here. – Mozahler Aug 02 '17 at 15:41

Solution was to set the newly created EKEventEditViewController as my existing UINavigationViewController of my desired ViewController, since EKEventEditViewController is of type UINavigationController itself.

let newNC = EKEventEditViewController()
self.navigationController = newNC

Afterwards, set newNC as childViewController of your current root UIViewController and add its view as a subview.
