Overview

An instance of the EKEvent class represents an event added to a calendar in the Event Kit framework.

Use the eventWithEventStore: method to create a new event. Use the properties in the class to get and modify certain information about an event. Other properties, such as the event’s title and calendar, are inherited from the parent class EKCalendarItem.
