# EKCalendarChooser

A view controller for determining whether a user may select one or more calendars.

```
class EKCalendarChooser
```

## Overview

Use the calendar chooser view controller to allow users to select one or more calendars when creating or editing a calendar event. The calendar chooser also lets you specify whether to display all calendars, or only those that may be written to. The view controller can be pushed on a navigation stack or presented modally.

Use a delegate that conforms to [`EKCalendarChooserDelegate`](/documentation/EventKitUI/EKCalendarChooserDelegate) to receive callbacks when the user selects calendars or cancels an operation.
