以编程方式在iPhone日历中添加自定义事件 [英] Programmatically add custom event in the iPhone Calendar

问题描述

有没有办法从自定义应用程序添加iCal事件到iPhone日历？

解决方案

基于 Apple文档，此

1）您应该通过requestAccessToEntityType：completion：请求访问用户日历，并在块中执行事件处理。

2）您需要立即提交事件或将commit参数传递给保存/删除调用

其他都保持不变...

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

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

添加活动：

  EKEventStore * store = [EKEventStore new]; 
 [store requestAccessToEntityType：EKEntityTypeEvent completion：^（BOOL granted，NSError * error）{
 if（！granted）{return; } 
 EKEvent * event = [EKEvent eventWithEventStore：store]; 
 event.title = @活动名称; 
 event.startDate = [NSDate date]; // today 
 event.endDate = [event.startDate dateByAddingTimeInterval：60 * 60]; // set 1 hours 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 
}]; 
  

删除活动：

  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，如果您有多个日历，一个是

Swift版本

您需要导入EventKit框架

  import EventKit 
  

$ b b

添加活动

  let store = EKEventStore（）
 store.requestAccessToEntityType（.Event）{ ，
 event.title =Event Title
 event.startDate = NSDate（），
， // today 
 event.endDate = event.startDate.dateByAddingTimeInterval（60 * 60）// 1小时长会议
 event.calendar = store.defaultCalendarForNewEvents 
 do {
 try store .saveEvent（event，span：.ThisEvent，commit：true）
 self.savedEventId = event.eventIdentifier //保存事件ID以便稍后访问此特定事件
} catch {
 //显示错误给用户
} 
} 
  

删除事件

let store = EKEventStore（）
store.requestAccessToEntityType（EKEntityTypeEvent）{（授予，错误）
if！granted {return }
let eventToRemove = store.eventWithIdentifier（self.savedEventId）
if eventToRemove！= nil {
do {
try store.removeEvent（eventToRemove，span：.ThisEvent，commit： true）
} catch {
//向用户显示错误
}
}
}


Is there any way to add iCal event to the iPhone Calendar from the custom App?

解决方案

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

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

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

Everything else stays the same...

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

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

To add an event:

    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:

    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

Swift version

You need to import the EventKit framework

import EventKit

Add event

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

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
        }
    }
}
