我正在尝试将所有日历中的特定事件复制到目标日历。不幸的是，我的活动没有保存在目标日历中。
只需我的代码步骤：
我确定有一些事件要从终端保存，打印“试图保存”几次。
它看起来像代码通过“try self.eventStore.save（event，span：.thisEvent）”并退出函数而不调用“已保存”或进入catch子句。
有一个源代码：
import UIKit
import EventKit
class ViewController: UIViewController{
@IBOutlet weak var status: UILabel!
var calendars: [EKCalendar]?
var targetCalendar: EKCalendar?
var targetCalendarEvents: [EKEvent]?
let eventStore = EKEventStore()
let targetCalendarName = "TargetCalendarName"
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func viewWillAppear(_ animated: Bool) {
DispatchQueue.main.async{
self.status.text = "Idle"
}
checkCalendarAuthorizationStatus()
}
func checkCalendarAuthorizationStatus() {
let status = EKEventStore.authorizationStatus(for: EKEntityType.event)
switch (status) {
case EKAuthorizationStatus.notDetermined:
// This happens on first-run
requestAccessToCalendar()
case EKAuthorizationStatus.authorized:
// Things are in line with being able to show the calendars in the table view
loadCalendars()
loadEvents()
case EKAuthorizationStatus.restricted, EKAuthorizationStatus.denied:
// We need to help them give us permission
print("Missing permissions [00]")
}
}
func requestAccessToCalendar() {
eventStore.requestAccess(to: EKEntityType.event, completion: {
(accessGranted: Bool, error: Error?) in
if accessGranted == true {
DispatchQueue.main.async(execute: {
self.loadCalendars()
self.loadEvents()
})
} else {
print("Missing permissions [01]")
}
})
}
func loadEvents(){
print("Loading..")
DispatchQueue.main.async{
self.status.text = "Loading"
}
let eventStore = EKEventStore()
var initialized = false
//Two months
let dateTo = NSDate(timeIntervalSinceNow: +30*24*3600 * 2)
for calendar in self.calendars! {
let predicate = eventStore.predicateForEvents(withStart: Date() as Date as Date, end: dateTo as Date, calendars: [calendar])
let events = eventStore.events(matching: predicate)
if calendar.title == targetCalendarName {
print("Initialized")
targetCalendar = calendar
targetCalendarEvents = events
initialized = true
}
}
if(!initialized){
print("Not Initialized")
} else {
for calendar in self.calendars! {
let predicate = eventStore.predicateForEvents(withStart: Date() as Date as Date, end: dateTo as Date, calendars: [calendar])
let events = eventStore.events(matching: predicate)
if calendar.title != targetCalendarName && calendar.title != "Contacts" {
//print("Loaded Calendar \(calendar.title)")
print("Loaded Calendar")
for event in events {
if(!(event.location?.isEmpty)!){
//print("Event \(event.location ?? "Missing Location") \(event.startDate) \(event.endDate)")
addEventToTarget(eventToAdd: event)
}
}
}
}
}
DispatchQueue.main.async {
self.status.text = "Done"
}
print("Done")
}
func loadCalendars() {
self.calendars = eventStore.calendars(for: EKEntityType.event)
}
func addEventToTarget(eventToAdd: EKEvent){
eventStore.requestAccess(to: .event) { (granted, error) in
for event in self.targetCalendarEvents! {
if(!(event.location?.isEmpty)!){
if(
eventToAdd.title == event.title &&
eventToAdd.startDate == event.startDate &&
eventToAdd.endDate == event.endDate
){
print("Possible duplicate - skipping")
return
}
}
}
if (granted) && (error == nil) {
let event:EKEvent = EKEvent(eventStore: self.eventStore)
event.title = eventToAdd.title
event.startDate = eventToAdd.startDate
event.endDate = eventToAdd.endDate
event.notes = ""
event.location = eventToAdd.location
event.calendar = self.targetCalendar
//print("Trying to save \(event.title) \(String(describing: event.location))")
print("Trying to save")
do {
try self.eventStore.save(event, span: .thisEvent)
print("Saved \(event.title) \(String(describing: event.location)) in \(event.calendar.title)")
} catch {
print("failed to save event with error : \(error as NSError)")
}
}
else{
print("failed to save event with error : \(String(describing: error)) or access not granted")
}
}
}
}
TargetCalendarName是正确的日历名称
有时会有成功保存的事件，但只有几个（2-5）可以保存。我不知道为什么。所以200对于200来说对我来说还不够。
感谢@matt提出解决方案。
现在我正在保存事件ONCE（之前我正在请求访问每个非常糟糕的事件），所以我请求访问eventStore一次并且可以成功保存事件。
func saveEvents(){
eventStore.requestAccess(to: .event) { (granted, error) in
if (granted) && (error == nil) {
for event in self.eventsToCopy {
print("Trying to save")
do {
try self.eventStore.save(event, span: .thisEvent)
print("Saved \(event.title) \(String(describing: event.location)) in \(event.calendar.title)")
} catch {
print("failed to save event with error : \(error as NSError)")
}
}
}
else{
print("failed to save event with error : \(String(describing: error)) or access not granted")
}
}
}
