【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。我有这段代码可以工作，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？我看到其他应用程序打开日历应用程序并预​​先填写字段。

//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: )
                    
                )

【参考方案1】：

您可以使用 Apple 的本机日历 API。在EventKitUI framework 中使用EKEventEditViewController，用户可以在保存事件时指定日历。在 Swift 3 中：

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：

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 中提供了NSCalendarsUsageDescription，您已经在requested access 中提供了requested access，等等。

【讨论】：

完美，正是我想要的。日历选项（选择要保存到哪个日历）确实出现在模式视图中。你知道我怎样才能让这个选项可见吗？

我不确定您所说的“使该选项可见”是什么意思（假设您刚刚说出现了日历选项）。如果设备有多个日历，它只会显示为事件的属性。如果用户没有多个日历，则没有。或者您是说您的设备有多个日历，而当事件呈现给用户进行编辑/添加/取消时，您没有看到日历选项？

我的错。我在模拟器上测试。我在设备上测试时很好。

【参考方案2】：

Apple 没有本机日历 API。

试试这个第三方库Calendar。它看起来与 ios 日历应用程序完全相同，并且还与 EKEventStore 集成。我在我的项目中使用了这个库，没有任何问题。

【参考方案3】：

在 swift 4.2 中完美运行

import UIKit
import EventKit
import EventKitUI

class yourViewController: UIViewController

    let eventStore = EKEventStore()

    func addEventToCalendar() 

    eventStore.requestAccess( to: EKEntityType.event, completion:(granted, error) in
        DispatchQueue.main.async 
            if (granted) && (error == nil) 
                let event = EKEvent(eventStore: self.eventStore)
                event.title = self.headerDescription
                event.startDate = self.parse(self.requestDetails.value(forKey: "session_time") as? String ?? "")
                event.endDate = self.parse(self.requestDetails.value(forKey: "session_end_time") as? String ?? "")
                let eventController = EKEventEditViewController()
                eventController.event = event
                eventController.eventStore = self.eventStore
                eventController.editViewDelegate = self
                self.present(eventController, animated: true, completion: nil)

            
        


       )
    

现在将出现下面的屏幕，您还可以在此处根据需要自定义详细信息：

// 现在在添加事件后关闭视图控制器

extension yourViewController: EKEventEditViewDelegate 

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

    

注意：不要忘记将 NSCalendarsUsageDescription 键添加到 info plist。
