Based on Apple Documentation, this has changed a bit as of iOS 6.0.

根据Apple 文档，这在 iOS 6.0 中发生了一些变化。

1) You should request access to the user's calendar via "requestAccessToEntityType:completion:" and execute the event handling inside of a block.

1) 您应该通过“requestAccessToEntityType:completion:”请求访问用户的日历并在块内执行事件处理。

2) You need to commit your event now or pass the "commit" param to your save/remove call

2）您需要立即提交事件或将“提交”参数传递给您的保存/删除调用

Everything else stays the same...

其他一切都保持不变......

Add the EventKit framework and #import <EventKit/EventKit.h>to your code.

将 EventKit 框架和添加#import <EventKit/EventKit.h>到您的代码中。

In my example, I have a NSString *savedEventId instance property.

在我的示例中，我有一个 NSString *savedEventId 实例属性。

To add an event:

添加事件：

    EKEventStore *store = [EKEventStore new];
    [store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
        if (!granted) { return; }
        EKEvent *event = [EKEvent eventWithEventStore:store];
        event.title = @"Event Title";
        event.startDate = [NSDate date]; //today
        event.endDate = [event.startDate dateByAddingTimeInterval:60*60];  //set 1 hour meeting
        event.calendar = [store defaultCalendarForNewEvents];
        NSError *err = nil;
        [store saveEvent:event span:EKSpanThisEvent commit:YES error:&err];
        self.savedEventId = event.eventIdentifier;  //save the event id if you want to access this later
    }];

Remove the event:

移除事件：

    EKEventStore* store = [EKEventStore new];
    [store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
        if (!granted) { return; }
        EKEvent* eventToRemove = [store eventWithIdentifier:self.savedEventId];
        if (eventToRemove) {
            NSError* error = nil;
            [store removeEvent:eventToRemove span:EKSpanThisEvent commit:YES error:&error];
        }
    }];

This adds events to your default calendar, if you have multiple calendars then you'll have find out which one that is

这会将事件添加到您的默认日历，如果您有多个日历，那么您将找出哪个是

You need to import the EventKit framework

您需要导入 EventKit 框架

import EventKit

Add event

添加事件

let store = EKEventStore()
store.requestAccessToEntityType(.Event) {(granted, error) in
    if !granted { return }
    var event = EKEvent(eventStore: store)
    event.title = "Event Title"
    event.startDate = NSDate() //today
    event.endDate = event.startDate.dateByAddingTimeInterval(60*60) //1 hour long meeting
    event.calendar = store.defaultCalendarForNewEvents
    do {
        try store.saveEvent(event, span: .ThisEvent, commit: true)
        self.savedEventId = event.eventIdentifier //save event id to access this particular event later
    } catch {
        // Display error to user
    }
}

Remove event

移除事件

let store = EKEventStore()
store.requestAccessToEntityType(EKEntityTypeEvent) {(granted, error) in
    if !granted { return }
    let eventToRemove = store.eventWithIdentifier(self.savedEventId)
    if eventToRemove != nil {
        do {
            try store.removeEvent(eventToRemove, span: .ThisEvent, commit: true)
        } catch {
            // Display error to user
        }
    }
}

You can do this using the Event Kit framework in OS 4.0.

您可以使用 OS 4.0 中的 Event Kit 框架执行此操作。

Right click on the FrameWorks group in the Groups and Files Navigator on the left of the window. Select 'Add' then 'Existing FrameWorks' then 'EventKit.Framework'.

在窗口左侧的 Groups and Files Navigator 中右键单击 FrameWorks 组。依次选择“添加”、“现有框架”和“EventKit.Framework”。

Then you should be able to add events with code like this:

然后你应该能够使用这样的代码添加事件：

#import "EventTestViewController.h"
#import <EventKit/EventKit.h>

@implementation EventTestViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    EKEventStore *eventStore = [[EKEventStore alloc] init];

    EKEvent *event  = [EKEvent eventWithEventStore:eventStore];
    event.title     = @"EVENT TITLE";

    event.startDate = [[NSDate alloc] init];
    event.endDate   = [[NSDate alloc] initWithTimeInterval:600 sinceDate:event.startDate];

    [event setCalendar:[eventStore defaultCalendarForNewEvents]];
    NSError *err;
    [eventStore saveEvent:event span:EKSpanThisEvent error:&err];       
}

@end

Yes there still is no API for this (2.1). But it seemed like at WWDC a lot of people were already interested in the functionality (including myself) and the recommendation was to go to the below site and create a feature request for this. If there is enough of an interest, they might end up moving the ICal.framework to the public SDK.

是的，这个（2.1）仍然没有API。但似乎在 WWDC 上，很多人已经对这个功能感兴趣（包括我自己），建议去下面的网站并为此创建一个功能请求。如果有足够的兴趣，他们最终可能会将 ICal.framework 移至公共 SDK。

Calendar access is being added in iPhone OS 4.0:

iPhone OS 4.0 中添加了日历访问：

Calendar Access
Apps can now create and edit events directly in the Calendar app with Event Kit.
Create recurring events, set up start and end times and assign them to any calendar on the device.

日历访问
应用程序现在可以使用 Event Kit 直接在日历应用程序中创建和编辑事件。
创建重复事件、设置开始和结束时间并将它们分配到设备上的任何日历。

You can add the event using the Event API like Tristan outlined and you can also add a Google Calendar event which shows up in the iOS calendar.

您可以使用事件 API 添加事件，例如 Tristan 概述，您还可以添加显示在 iOS 日历中的 Google 日历事件。

using Google's API Objective-C Client

使用Google 的 API Objective-C 客户端

  - (void)addAnEvent {
  // Make a new event, and show it to the user to edit
  GTLCalendarEvent *newEvent = [GTLCalendarEvent object];
  newEvent.summary = @"Sample Added Event";
  newEvent.descriptionProperty = @"Description of sample added event";

  // We'll set the start time to now, and the end time to an hour from now,
  // with a reminder 10 minutes before
  NSDate *anHourFromNow = [NSDate dateWithTimeIntervalSinceNow:60*60];
  GTLDateTime *startDateTime = [GTLDateTime dateTimeWithDate:[NSDate date]
                                                    timeZone:[NSTimeZone systemTimeZone]];
  GTLDateTime *endDateTime = [GTLDateTime dateTimeWithDate:anHourFromNow
                                                  timeZone:[NSTimeZone systemTimeZone]];

  newEvent.start = [GTLCalendarEventDateTime object];
  newEvent.start.dateTime = startDateTime;

  newEvent.end = [GTLCalendarEventDateTime object];
  newEvent.end.dateTime = endDateTime;

  GTLCalendarEventReminder *reminder = [GTLCalendarEventReminder object];
  reminder.minutes = [NSNumber numberWithInteger:10];
  reminder.method = @"email";

  newEvent.reminders = [GTLCalendarEventReminders object];
  newEvent.reminders.overrides = [NSArray arrayWithObject:reminder];
  newEvent.reminders.useDefault = [NSNumber numberWithBool:NO];

  // Display the event edit dialog
  EditEventWindowController *controller = [[[EditEventWindowController alloc] init] autorelease];
  [controller runModalForWindow:[self window]
                          event:newEvent
              completionHandler:^(NSInteger returnCode, GTLCalendarEvent *event) {
                // Callback
                if (returnCode == NSOKButton) {
                  [self addEvent:event];
                }
              }];

Swift 4.0 implementation :

Swift 4.0 实现：

use import in top of page by import EventKit

在页面顶部使用导入 import EventKit

then

然后

@IBAction func addtoCalendarClicked(sender: AnyObject) {

    let eventStore = EKEventStore()

    eventStore.requestAccess( to: EKEntityType.event, completion:{(granted, error) in

        if (granted) && (error == nil) {
            print("granted \(granted)")
            print("error \(error)")

            let event = EKEvent(eventStore: eventStore)

            event.title = "Event Title"
            event.startDate = Date()

also don't forget to add permission for calendar usage

也不要忘记添加日历使用权限

Working code in Swift-4.2

Swift-4.2 中的工作代码

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)

            }
        }


       })
    }

}

Now we will get the event screen and here you can also modify your settings:

现在我们将获得事件屏幕，您还可以在此处修改设置：

Now add delegate method to handle Cancel and add the event button action of event screen:

现在添加委托方法来处理取消并添加事件屏幕的事件按钮动作：

    extension viewController: EKEventEditViewDelegate {

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

    }
}

Note:Don't forget to add NSCalendarsUsageDescriptionkey into info plist.

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

Remember to set the endDate to the created event, it is mandatory.

请记住将 endDate 设置为创建的事件，这是强制性的。

Otherwise it will fail (almost silently) with this error:

否则它将失败（几乎是无声的）并出现以下错误：

"Error Domain=EKErrorDomain Code=3 "No end date has been set." UserInfo={NSLocalizedDescription=No end date has been set.}"

The complete working code for me is:

对我来说完整的工作代码是：

EKEventStore *store = [EKEventStore new];
[store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
    if (!granted) { return; }
    EKEvent *calendarEvent = [EKEvent eventWithEventStore:store];
    calendarEvent.title = [NSString stringWithFormat:@"CEmprendedor: %@", _event.name];
    calendarEvent.startDate = _event.date;
    // 5 hours of duration, we must add the duration of the event to the API
    NSDate *endDate = [_event.date dateByAddingTimeInterval:60*60*5];
    calendarEvent.endDate = endDate;
    calendarEvent.calendar = [store defaultCalendarForNewEvents];
    NSError *err = nil;
