如何使用 swift 在设备日历中添加事件？

Question

我想知道如何在设备中添加日历事件，但使用 swift。我知道 Objective-C 中有一些示例，但目前 swift 中没有任何示例。非常感谢。

Answer 1

注意：如果您的应用因 This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCalendarsUsageDescription key with a string value explaining to the user how the app uses this data. 而崩溃，您需要将 NSCalendarsUsageDescription 添加到 info.plist。可以仿照例子.

Swift 5.0 版本

import Foundation
import EventKit

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")
  }
}

我能够对此进行调整并消除上述答案（以及其他一些）的评论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，我仍然在底部收到关于 "EKSpan.ThisEvent" 的以下错误：调用中的参数标签不正确（有':span:error:'，预期为' ：跨度：提交：'）。

我尝试将 "error" 更改为 "commit," 但它给了我一个编译器错误，说它需要一个 Bool 而不是 nil。这似乎是一个与 swift 语法更新有关的问题。

编辑：我最终关注了 this tutorial 并且能够让它发挥作用。

首先，请求访问日历的权限，并且（如果授予该权限）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)
    }
}

上面代码片段中调用的添加事件的函数：

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")
    }
}

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?)
        }
    })
}

同时导入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实用程序 class 中并将其定义为 'static'。

您需要将 "Privacy - Calendars Usage Description" 添加到 info.plist。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")
    }
}

这在 iOS 11.2 Xcode 9.2 上真的很慢，所以我修改了 Luca Davanzo 的答案以使用队列（工作得更快）：

func addEventToCalendar(title: String, description: String?, startDate: Date, endDate: Date, completion: ((_ success: Bool, _ error: NSError?) -> Void)? = nil) {
        DispatchQueue.global(qos: .background).async { () -> Void in
            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?)
                }
            })
        }
    }

与位置和警报相同

   func addEventToCalendar(title: String, description: String?, startDate: Date, endDate: Date, location: String?, completion: ((_ success: Bool, _ error: NSError?) -> Void)? = nil) {
    DispatchQueue.global(qos: .background).async { () -> Void in
        let eventStore = EKEventStore()

        eventStore.requestAccess(to: .event, completion: { (granted, error) in
            if (granted) && (error == nil) {
                let alarm = EKAlarm(relativeOffset: -3600.0)
                let event = EKEvent(eventStore: eventStore)
                event.title = title
                event.startDate = startDate
                event.endDate = endDate
                event.notes = description
                event.alarms = [alarm]
                event.location = location
                event.calendar = eventStore.defaultCalendarForNewEvents
                do {
                    try eventStore.save(event, span: .thisEvent)
                } catch let e as NSError {
                    completion?(false, e)
                    print ("\(#file) - \(#function) error: \(e.localizedDescription)")
                    return
                }
                completion?(true, nil)
            } else {
                completion?(false, error as NSError?)
                print ("\(#file) - \(#function) error: \(error)")
            }
        })
    }
}
