我正在尝试删除我在日历中保存的带有事件 ID 的事件，但它会删除不同的事件，有时它不会删除任何内容。
我在创建事件时将 eventId 保存在领域数据库中，并在我想删除但它不起作用时将其读回。
我尝试在实际设备上运行它，使用数组而不是字典，将跨度更改为.futureEvents但仍然不起作用
我用于创建事件并保存到领域数据库的代码
/// function exits in another class
func addEventToCalendar(userName: String, userDate: Date) {
let userDefaults = UserDefaults.standard
let eventStore: EKEventStore = EKEventStore()
eventStore.requestAccess(to: .event) { (granted, error) in
if (granted) && (error == nil) {
print("granted \(granted)")
print("error \(String(describing: error))")
let event: EKEvent = EKEvent(eventStore: eventStore)
event.title = "\(userName) Birthday"
event.startDate = userDate
event.endDate = userDate
event.notes = "Happy Birthday!"
event.isAllDay = true
event.calendar = eventStore.defaultCalendarForNewEvents
let ekrules: EKRecurrenceRule = EKRecurrenceRule.init(recurrenceWith: .yearly, interval: 1, end: nil)
event.recurrenceRules = [ekrules]
//event.addAlarm(EKAlarm(absoluteDate: event.startDate))
//sets alert 00:00 on day of event
event.addAlarm(EKAlarm(relativeOffset: 0))
do {
try eventStore.save(event, span: .thisEvent, commit: true)
} catch let error as NSError {
print("error: \(error)")
}
let eventId = event.eventIdentifier ?? "nil-id"
userDefaults.setValue(eventId, forKey: "eventId")
print(eventId)
} else {
print("error not granted: \(String(describing: error))")
}
}
}
//saving it in a view controller class
@IBAction func okBtnPressed(_ sender: UIButton) {
let eventId = UserDefaults.standard.string(forKey: "eventId") ?? "no-id"
//// saving data to device
let newItem = Item()
newItem.userImageName = String(describing: userImageUrl)
newItem.userName = uName
newItem.isYearPresent = uYearPresent
newItem.userDOB = uDOB
newItem.color = UIColor.init(randomFlatColorOf: .dark).hexValue()
newItem.daysRemaining = daysRemain
newItem.eventId = eventId
self.save(item: newItem)
}
事件 id 成功保存在领域数据库中。
从日历中删除事件的功能
func removeEvent(id: String) {
let store = EKEventStore()
store.requestAccess(to: .event) { (granted, error) in
if !granted { return }
// checking if event exists
if let eventToRemove = store.event(withIdentifier: id) {
do {
print("removing: \(id)")
try store.remove(eventToRemove, span: .thisEvent, commit: true)
print("event removed sucessfully")
} catch let error as NSError {
print("error: \(error)")
}
} else {
print("event doesnt exist.")
}
}
}
这就是我删除它的方式
var eventIDS = [Int: String]()
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// inserting evenIds to dictionary to access it in remove function
// I used an array but it gave me the same problem
if let item = itemsObject?[indexPath.row] {
eventIDS[indexPath.row] = item.eventId
}
}
// then I call remove function when swipe taps on cell
removeEvent(id: self.eventIDS[indexPath.row] ?? "")
有时我成功删除了事件，但它删除了另一个事件，有时我收到以下错误
Error getting event with identifier 2BD633CA-BBEA-47CD-8410-40BCE6362A5C:98D9EAF2-D5EF-420F-B769-7F02B7795E54: Error Domain=EKCADErrorDomain Code=1010 "(null)"
event doesnt exist.
