将事件保存到用户的日历 [英] Save event to user's calendar

问题描述

如何将事件添加到用户的日历中，然后允许用户选择日历等。我有此代码可用，但这会将事件添加到用户的默认日历中。如何允许用户更改日历，自定义警报等？我见过其他应用程序打开日历应用程序并预​​先填写字段。

How do you add an event to the user's calendar, but then allow the user to choose the calendar, etc. I have this code that works, but this adds the event to the user's default calendar. How do I allow the user to change the calendar, customize the alerts etc? I have seen other apps open the calendar app and pre-fill the fields.

//add to calendar
                let eventStore : EKEventStore = EKEventStore()
                eventStore.requestAccessToEntityType(EKEntityType.Event, completion: { (granted, error) in
                    if granted && error == nil {
                        let event:EKEvent = EKEvent(eventStore: eventStore)

                        event.title = "My event: " + self.event.name
                        event.startDate = self.event.startTime
                        event.endDate = self.event.endTime
                        event.notes = self.event.description
                        event.calendar = eventStore.defaultCalendarForNewEvents

                        do {
                            try eventStore.saveEvent(event, span: .ThisEvent, commit: true)
                            self.dismissViewControllerAnimated(true, completion: {})
                        } catch {
                            self.dismissViewControllerAnimated(true, completion: {})
                        }
                    } else {
                        self.dismissViewControllerAnimated(true, completion: {})
                    }
                })

推荐答案

您可以使用Apple的原生日历API。在 EKEventEditViewController href =https://developer.apple.com/reference/eventkitui =noreferrer> EventKitUI框架，用户可以在保存事件时指定日历。在Swift 3中：

You can use Apple's native calendar API. Use EKEventEditViewController in the EventKitUI framework, and the user will be able to specify the calendar when saving the event. In Swift 3:

import UIKit
import EventKit
import EventKitUI

class ViewController: UIViewController {

    let store = EKEventStore()

    func createEvent() {
        // create the event object

        let event = EKEvent(eventStore: store)
        event.title = "Foo"
        event.startDate = ...
        event.endDate = ...

        // prompt user to add event (to whatever calendar they want)

        let controller = EKEventEditViewController()
        controller.event = event
        controller.eventStore = store
        controller.editViewDelegate = self
        present(controller, animated: true)
    }
}

extension ViewController: EKEventEditViewDelegate {

    func eventEditViewController(_ controller: EKEventEditViewController, didCompleteWith action: EKEventEditViewAction) {
        controller.dismiss(animated: true)
    }
}

在Swift 2.3中：

In Swift 2.3:

import UIKit
import EventKit
import EventKitUI

class ViewController: UIViewController {

    let store = EKEventStore()

    func createEvent() {
        // create the event object

        let event = EKEvent(eventStore: store)
        event.title = "Foo"
        event.startDate = ...
        event.endDate = ...

        // prompt user to add event (to whatever calendar they want)

        let controller = EKEventEditViewController()
        controller.event = event
        controller.eventStore = store
        controller.editViewDelegate = self
        presentViewController(controller, animated: true, completion: nil)
    }
}

extension ViewController: EKEventEditViewDelegate {

    func eventEditViewController(controller: EKEventEditViewController, didCompleteWithAction action: EKEventEditViewAction) {
        controller.dismissViewControllerAnimated(true, completion: nil)
    }
}

这假设您在 Info.plist NSCalendarsUsageDescription >，您已请求的访问权限等。

This assumes that you've supplied a NSCalendarsUsageDescription in your Info.plist, that you've requested access, etc.
