Going from event editor back to calendar creates blacked out area near bottom

Question

I've encountered this problem both in my own CalendarKit app as well as the sample app found here. The issue is that when I click on an event and enter the EKEventViewController and then navigate back, the calendar now looks like this:. Looking at the view hierarchy, it looks like the TimelineView has been truncated at the bottom a little. Any idea on what's going on/how to fix? Thanks.

I tried using present instead of pushing navigation controller, but then the "Delete Event" button on the bottom of the EKEventViewController just doesn't show up.

Answer 1

It's a bug in EventKitUI framework projecting itself onto the other ViewControllers. To fix it, add this line to CalendarViewController:

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        navigationController?.setToolbarHidden(true, animated: false)
    }

This will solve your issue.
