如何使用swift在设备日历中添加事件

Question

我有兴趣知道如何在设备中添加日历事件,但使用swift.我知道在Objective-C中有一些例子,但目前没什么好快的.非常感谢.

Answer 1

Swift 3.0版

    let eventStore : EKEventStore = EKEventStore()

    // 'EKEntityTypeReminder' or 'EKEntityTypeEvent'

    eventStore.requestAccess(to: .event) { (granted, error) in

        if (granted) && (error == nil) {
            print("granted \(granted)")
            print("error \(error)")

            let event:EKEvent = EKEvent(eventStore: eventStore)

            event.title = "Test Title"
            event.startDate = Date()
            event.endDate = Date()
            event.notes = "This is a note"
            event.calendar = eventStore.defaultCalendarForNewEvents
            do {
                try eventStore.save(event, span: .thisEvent)
            } catch let error as NSError {
                print("failed to save event with error : \(error)")
            }
            print("Saved Event")
        }
        else{

            print("failed to save event with error : \(error) or access not granted")
        }
    }

Swift 3.0兼容:

func addEventToCalendar(title: String, description: String?, startDate: Date, endDate: Date, completion: ((_ success: Bool, _ error: NSError?) -> Void)? = nil) {
    let eventStore = EKEventStore()

    eventStore.requestAccess(to: .event, completion: { (granted, error) in
        if (granted) && (error == nil) {
            let event = EKEvent(eventStore: eventStore)
            event.title = title
            event.startDate = startDate
            event.endDate = endDate
            event.notes = description
            event.calendar = eventStore.defaultCalendarForNewEvents
            do {
                try eventStore.save(event, span: .thisEvent)
            } catch let e as NSError {
                completion?(false, e)
                return
            }
            completion?(true, nil)
        } else {
            completion?(false, error as NSError?)
        }
    })
}

还进口 EventKit

因此,您可以从任何地方轻松调用此方法:

addEventToCalendar(title: "Girlfriend birthday", description: "Remember or die!", startDate: NSDate(), endDate: NSDate())

如果您愿意,可以将此方法放在一个utiliy类中,并将其定义为"static".

Answer 3

您需要在info.plist中添加"隐私 - 日历使用说明".以下代码适用于最新版本的xcode和swift 3.

import EventKit
class EventHelper
{
    let appleEventStore = EKEventStore()
    var calendars: [EKCalendar]?
    func generateEvent() {
        let status = EKEventStore.authorizationStatus(for: EKEntityType.event)

        switch (status)
        {
        case EKAuthorizationStatus.notDetermined:
            // This happens on first-run
            requestAccessToCalendar()
        case EKAuthorizationStatus.authorized:
            // User has access
            print("User has access to calendar")
            self.addAppleEvents()
        case EKAuthorizationStatus.restricted, EKAuthorizationStatus.denied:
            // We need to help them give us permission
            noPermission()
        }
    }
    func noPermission()
    {
        print("User has to change settings...goto settings to view access")
    }
    func requestAccessToCalendar() {
        appleEventStore.requestAccess(to: .event, completion: { (granted, error) in
            if (granted) && (error == nil) {
                DispatchQueue.main.async {
                    print("User has access to calendar")
                    self.addAppleEvents()
                }
            } else {
                DispatchQueue.main.async{
                    self.noPermission()
                }
            }
        })
    }
    func addAppleEvents()
    {
        let event:EKEvent = EKEvent(eventStore: appleEventStore)
        event.title = "Test Event"
        event.startDate = NSDate() as Date
        event.endDate = NSDate() as Date
        event.notes = "This is a note"
        event.calendar = appleEventStore.defaultCalendarForNewEvents

        do {
            try appleEventStore.save(event, span: .thisEvent)
            print("events added with dates:")
        } catch let e as NSError {
            print(e.description)
            return
        }   
        print("Saved Event")
    }
}

Answer 4

我能够进行调整，并消除了上述答案（以及其他一些答案）的注释中提到的编译器错误，如下所示：

 var eventStore : EKEventStore = EKEventStore()

    // 'EKEntityTypeReminder' or 'EKEntityTypeEvent'

    eventStore.requestAccessToEntityType(EKEntityType.Event, completion: {
        (granted, error) in

        if (granted) && (error == nil) {
            print("granted \(granted)")
            print("error \(error)")

            var event:EKEvent = EKEvent(eventStore: eventStore)

            event.title = "Test Title"
            event.startDate = NSDate()
            event.endDate = NSDate()
            event.notes = "This is a note"
            event.calendar = eventStore.defaultCalendarForNewEvents

            eventStore.saveEvent(event, span: EKSpan.ThisEvent, error: nil)

            print("Saved Event")
        } 
    })

但是，关于“ EKSpan.ThisEvent”，我仍然在底部收到以下错误：调用中的参数标签不正确（具有' ：span：error：'，预期为'：span：commit：'）。

我尝试将“错误”更改为“提交”，但是它给了我一个编译器错误，表明它期望使用Bool而不是nil。似乎与快速语法更新有关的问题。

编辑：我结束了本教程，并能够使其正常工作。

1. 首先，询问访问日历的权限，然后（如果已授予该权限）调用一个函数来添加事件。

   var savedEventId : String = ""
   
   func requestAccessPermission() {
       let eventStore = EKEventStore()
   
       let startDate = NSDate()
       let endDate = startDate.dateByAddingTimeInterval(60 * 60) // Ends one hour later
   
       if (EKEventStore.authorizationStatusForEntityType(.Event) != EKAuthorizationStatus.Authorized) {
           eventStore.requestAccessToEntityType(.Event, completion: {
           granted, error in
               self.createEvent(eventStore, title: "Test Title", startDate: startDate, endDate: endDate)
           })
       } else {
           createEvent(eventStore, title: "Test Title", startDate: startDate, endDate: endDate)
       }
   }
   

2. 上面的代码片段中调用的用于添加事件的函数：

   func createEvent(eventStore: EKEventStore, title: String, startDate: NSDate, endDate: NSDate) {
       let event = EKEvent(eventStore: eventStore)
       event.title = title
       event.startDate = startDate
       event.endDate = endDate
       event.calendar = eventStore.defaultCalendarForNewEvents
       do {
           try eventStore.saveEvent(event, span: .ThisEvent)
           savedEventId = event.eventIdentifier
       } catch {
           print("Error Saving")
       }
   }
