在EKEventViewController中点击后退按钮时隐藏删除按钮

Question

I have using EkEventViewController to view event in my app.

My code should be like below:

 func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
       let eventViewController = EkEventViewController()
       eventViewController.delegate = self
       eventViewController.allowsEditing = true
       eventViewController.allowsCalendarPreview = true
       eventViewController.hidesBottomBarWhenPushed = true
       eventViewController.event = self.events[indexPath.row]
       self.navigationController?.pushViewController(eventViewController, animated: true)
    }

When I tap back button from EkEventViewController . The delete button bar should not hide. How to hide or remove delete bottom button bar

Answer 1

Based on your question, I presume that the 'delete' button or border retains after tapping on back button from EKEventViewController . The delete button from EKEventViewController is actually from toolbar in navigationController . You can hide the toolbar via setToolbarHidden(_ hidden: Bool, animated: Bool)

To do so, you have to initialize a new class with the subclass of EKEventViewController and push your view controller to it. Then, add the line below in your viewWillDisappear of the new class:

    self.navigationController?.setToolbarHidden(true, animated: false)

Do note that this solution is based on assumption that you do not have existing toolbar prior to calling the EKEventViewController .
