Question

我想知道是否有人知道如何使用APP中的特定事件启动日历

我已经完成了一些研究，并且我已经提出了两种使用NSURL从应用内部打开原生日历的方法

"calshow://"在当前日期打开日历
"calshow:\(someNSDate.timeIntervalSinceReferenceDate)"，会打开日期为someNSDate

我还发现this website列出了calshow:x?eventid=id作为网址，但我不确定这是否有效（列为非公开）并且我无法让自己工作，尝试过使用：

event.calendarItemExternalIdentifier
event.eventIdentifier
event.calendarItemIdentifier

目前我正在使用此代码在finalInterval日期，事件日期打开日历应用

        if let day = hackathon?.start {

            let today = NSDate()
            let timeSince = NSDate.timeIntervalSinceReferenceDate() // this plus
            let todayToFutureDate = day.timeIntervalSinceDate(today)
            let finalInterval = todayToFutureDate + timeSince

            UIApplication.sharedApplication().openURL(NSURL(string: "calshow:\(finalInterval)")!)
        }

我想要做的是打开带有活动ID的日历或类似事件的日历

如果您对更多信息有任何疑问，请询问，我会在附近

Answer 1

试试这个，创建这个功能

func gotoAppleCalendar(date: NSDate) {
  let interval = date.timeIntervalSinceReferenceDate
  let url = NSURL(string: "calshow:\(interval)")!
  UIApplication.sharedApplication().openURL(url)
}

使用事件开始日期作为参数

调用该函数

 gotoAppleCalendar(event.startDate)

这打开了显示添加事件的苹果日历

Swift 4变种+

func gotoAppleCalendar(date: Date) {
     let interval = date.timeIntervalSinceReferenceDate
     let url = URL(string: "calshow:\(interval)")!
     UIApplication.shared.openURL(url)
 }

Answer 3

当然这就是我要澄清的内容......你说你会看到一个“添加的事件”......好像你用你编写的代码添加了事件，但是你没有这样做。

当您正在搜索如何在Google上添加日历事件并获得“添加事件”的答案时，这很令人困惑

Swift 4 CalendarService，可以创建事件和打开日历。

import Foundation
import EventKit
import UIKit

final class CalendarService {

  class func openCalendar(with date: Date) {
    guard let url = URL(string: "calshow:\(date.timeIntervalSinceReferenceDate)") else {
      return
    }
    UIApplication.shared.open(url, options: [:], completionHandler: nil)
  }

  class 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 {
            DispatchQueue.main.async {
              completion?(false, e)
            }
            return
          }
          DispatchQueue.main.async {
            completion?(true, nil)
          }
        } else {
          DispatchQueue.main.async {
            completion?(false, error as NSError?)
          }
        }
      })
    }
  }
}

使用

CalendarService.addEventToCalendar(title: "TITLE",
                                               description: "DESCRIPTION",
                                               startDate: startDate,
                                               endDate: endDate,
                                               completion: { (success, error) in
                                                if success {
                                                    CalendarService.openCalendar(with: startDate)
                                                } else if let error = error {
                                                    print(error)
                                                }
    })
