title: iOS EKEvent Store recreating iCloud calendars in a loop, won't save local.
body: <p>I'm having a strange issue EKEventStore, iCloud and local calendars. If iCloud is enabled the Calendar is created and events are saved into the calendar as you would expect. if iCloud is turned off and you try to save an event nothing happens, however the device continues to create iCloud calendars in a loop every 3-5 seconds until iCloud is turned back on and then all of those calendars flood into iCloud as duplicates. I'm using nearly the exact code that has been referenced here on SO many times as well as in Apples Docs. I'm completely stumped as to why it's not working and there seems to be very little documentation on EKEventStore in general. </p>
