I have an EKEvent that occurs every 4 hours, and I want to create a single recurring event.
Unfortunately the available frequencies in the EKRecurrenceRule class are daily, weekly, monthly, and yearly.
How can I set hourly frequency for the EKRecurrenceRule object ?
Unfortunately there is no way to make hourly events using the EKRecurrenceRule objects, but you can still write a method which would do the same.
func createHourlyRecurringEvent(eventTitle: String, startDate: NSDate, endDate: NSDate, endReccurenceDate: NSDate, allDay : Bool, recurrenceSecondsInterval: Double, alarms: [EKAlarm]? , travelTime: Int?) {
var eventStartDate = startDate
var eventEndDate = endDate
while eventStartDate.earlierDate(endReccurenceDate) != endReccurenceDate {
let event = EKEvent(eventStore: self.eventStore)
event.title = eventTitle
event.startDate = eventStartDate
event.endDate = eventEndDate
event.allDay = allDay
event.alarms = alarms
event.calendar = eventStore.defaultCalendarForNewEvents
if let travelTime = travelTime {
event.setValue(travelTime, forKey: "travelTime")
}
do {
try eventStore.saveEvent(event, span: .ThisEvent)
print("Hourly event created)")
print("start date: \(formatter.stringFromDate(event.startDate)")
print("End date: \(formatter.stringFromDate(event.endDate))")
} catch {
print("Event failed to save")
}
eventStartDate = NSDate(timeInterval: recurrenceSecondsInterval, sinceDate: event.startDate)
eventEndDate = NSDate(timeInterval: recurrenceSecondsInterval, sinceDate: event.endDate)
}
}
This code sits inside my Schedule class. After creating an instance of the schedule I can create an hourly recurring event like this:
let startDate = NSDate()
let endDate = NSDate(timeInterval: 10800, sinceDate: startDate)
let oneWeekInSeconds = 604800.0
let endRecurrenceDate = NSDate(timeInterval: oneWeekInSeconds, sinceDate: NSDate())
let fourHours = 14400.0
schedule!.createHourlyRecurringEvent("Testing",
startDate: startDate,
endDate: endDate,
endReccurenceDate: endRecurrenceDate,
allDay: false,
recurrenceSecondsInterval: fourHours,
alarms: nil,
travelTime: nil)
Deleting the individual events is simple, like so:
func deleteEvent(eventToRemove: EKEvent) -> Bool {
var successful = false
do {
print("deleting single event")
try self.eventStore.removeEvent(eventToRemove, span: .ThisEvent)
successful = true
} catch {
print("Bad things happened")
}
return successful
}
I've yet to find a good way to batch delete all the events because they all have different unique IDs. Ill update this post when I find a good way.
