以编程方式在 iPhone 日历中添加自定义事件

Question

有没有办法从自定义 App 中将 iCal 事件添加到 iPhone 日历？

Answer 1

是的，仍然没有用于此的 API (2.1)。但似乎在 WWDC 上，很多人（包括我自己）已经对该功能感兴趣，建议访问以下站点并为此创建功能请求。如果有足够的兴趣，他们最终可能会将 ICal.framework 移至公共 SDK。

Answer 2

Google 的想法不错，但也有问题。

我可以成功打开 Google 日历活动屏幕 - 但仅限于主桌面版本，并且在 iPhone Safari 上无法正常显示。 Google 移动日历在 Safari 上可以正常显示，但似乎无法使用 API 添加事件。

目前，我看不出有什么好的出路。

Answer 3

Calendar access is being added in iPhone OS 4.0:

日历访问
应用程序现在可以直接在 带有 Event Kit 的日历应用程序。
创建重复事件，设置开始和结束 时间并将它们分配给任何日历 在设备上。

Answer 4

您可以使用 OS 4.0 中的 Event Kit 框架来做到这一点。

在窗口左侧的 Groups and Files Navigator 中右键单击 FrameWorks 组。选择“添加”，然后选择“现有框架”，然后选择“EventKit.Framework”。

那么您应该可以使用如下代码添加事件：

#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

Answer 5

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

使用Google's API Objective-C Client

  - (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];
                }
              }];
}

简单....使用tapku库....你可以谷歌这个词并使用它...它的开源......享受......不需要那些代码的窃听......

Answer 7

基于Apple Documentation，这在 iOS 6.0 中有所改变。

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) 您现在需要提交您的事件或将“提交”参数传递给您的保存/删除调用

其他一切都保持不变...

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

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

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
    }];

删除事件：

    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];
        }
    }];

这会将事件添加到您的默认日历中，如果您有多个日历，那么您将找出是哪一个

Swift 版本

需要导入 EventKit 框架

import EventKit

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
    }
}

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
        }
    }
}

Swift 4.0 实现：

通过import EventKit在页面顶部使用导入

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()
            event.endDate = Date()
            event.notes = "Event Details Here"
            event.calendar = eventStore.defaultCalendarForNewEvents

            var event_id = ""
            do {
                try eventStore.save(event, span: .thisEvent)
                event_id = event.eventIdentifier
            }
            catch let error as NSError {
                print("json error: \(error.localizedDescription)")
            }

            if(event_id != ""){
                print("event added !")
            }
        }
    })
}

Answer 9

记得将 endDate 设置为创建的事件，这是强制性的。

否则它将失败（几乎无声）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.}"

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;
    [store saveEvent:calendarEvent span:EKSpanThisEvent commit:YES error:&err];
    self.savedEventId = calendarEvent.eventIdentifier;  //saving the calendar event id to possibly deleted them
}];

Dashrath 答案的 swift 4 更新

import UIKit
import EventKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let eventStore = EKEventStore()

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

            if (granted) && (error == nil) {


                let event = EKEvent(eventStore: eventStore)

                event.title = "My Event"
                event.startDate = Date(timeIntervalSinceNow: TimeInterval())
                event.endDate = Date(timeIntervalSinceNow: TimeInterval())
                event.notes = "Yeah!!!"
                event.calendar = eventStore.defaultCalendarForNewEvents

                var event_id = ""
                do{
                    try eventStore.save(event, span: .thisEvent)
                    event_id = event.eventIdentifier
                }
                catch let error as NSError {
                    print("json error: \(error.localizedDescription)")
                }

                if(event_id != ""){
                    print("event added !")
                }
            }
        })
    }

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


}

别忘了添加日历使用权限

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)

            }
        }


       })
    }

}

现在我们将获得事件屏幕，您还可以在此处修改设置：

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)

    }
}

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