Programmatically show EKEventEditViewController in EKEventViewController

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!

Solution

  • 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.
