Question

我是swift的新手，我在这个网站上练习“添加日历活动”：http://www.ioscreator.com/tutorials/add-event-calendar-tutorial-ios8-swift，但我在行中遇到以下错误

 let result = store.saveEvent(event, span: .ThisEvent, commit: error)

Call can throw, but it is not marked with 'try' and the error is not handled
Cannot convert value of type 'NSError?' to expected argument type 'Bool'

代码：

import UIKit
import EventKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        let eventStore = EKEventStore()
        switch EKEventStore.authorizationStatusForEntityType(EKEntityType.Event) {
        case .Authorized:
            insertEvent(eventStore)
        case .Denied:
            print("Access denied")
        case .NotDetermined:
            // 3
            eventStore.requestAccessToEntityType(EKEntityType.Event, completion:
                {[weak self] (granted: Bool, error: NSError?) -> Void in
                    if granted {
                        self!.insertEvent(eventStore)
                    } else {
                        print("Access denied")
                    }
                })
        default:
            print("Case Default")
        }

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func insertEvent(store : EKEventStore){
        let calendars = store.calendarsForEntityType(EKEntityType.Event) as! [EKCalendar]
        for calendar in calendars{
            if calendar.title == "ioscreater"{
                let startDate = NSDate()
                let endDate = startDate.dateByAddingTimeInterval(2*60*60)
                //Create event
                var event = EKEvent(eventStore : store)
                event.calendar = calendar
                event.title = "New Meeting"
                event.startDate = startDate
                event.endDate = endDate
                //Save event in Calendar
                var error : NSError?
                let result = store.saveEvent(event, span: .ThisEvent, commit: error)
                if result == false{
                    if let theError = error{
                        print ("An error occured \(theError)")
                    }
                }
            }

        }

    }

}

我搜索了错误，但找不到合适的解决方案。

func insertEvent(store : EKEventStore){
    let calendars = store.calendarsForEntityType(EKEntityType.Event)
    for calendar in calendars{
        if calendar.title == "ioscreater"{
            let startDate = NSDate()
            let endDate = startDate.dateByAddingTimeInterval(2*60*60)
            //Create event
            var event = EKEvent(eventStore : store)
            event.calendar = calendar
            event.title = "New Meeting"
            event.startDate = startDate
            event.endDate = endDate
            //Save event in Calendar
            do {
                try store.saveEvent(event, span: .ThisEvent)
            } catch {
                // Do error stuff here
            }
        }

这适用于 Swift 3.0

首先，您需要添加＆＃34;隐私 - 日历使用说明＆＃34;在info.plist。

import EventKit

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?)
        }
    }) 
}

然后，您可以轻松地调用此方法，如下所示：

addEventToCalendar(title: "Best friend birthday", description: "Remember you or miss you!", startDate: NSDate(), endDate: NSDate())

谢谢并享受编码!!!

Answer 3

在try中添加saveEvent代码，如下所示：

      do {
         try store.saveEvent(event, span: .ThisEvent)
                } catch let err as NSError{
                     print ("An error occured \(err.description)")
                }
