ios 日历事件

EventKit框架

iOS 4.0引入了EventKit框架 (EventKit.framework)。此框架为访问用户设备的日历事件提供接口。您可以通过该框架访问用户日历中现有事件，可以增加新事件。日历事件可包含闹铃，而且可以配置闹铃激活规则。

一：using enevt kit

1：get existing events

2:create new events

3:delete events

4:be notified of event changes

二：create new events

1：addEventKit.framework

2：导入头文件

 <fontclass="Apple-style-span"style="font-weight:normal;text-indent:0px;line-height:normal;font-style:normal;white-space:normal;letter-spacing:normal;border-collapse:separate;font-variant:normal;"size="4"color="#000000"><fontclass="Apple-style-span"style="font-size:14px;text-indent:28px;line-height:28px;"color="#333333">#import<EventKit/EventKit.h></font></font>

3:

 -(IBAction)createEvent{

 //Gettheeventstoreobject
 EKEventStore*eventStore=[[EKEventStorealloc]init];

 //Createanewevent
 EKEvent*event=[EKEventeventWithEventStore:eventStore];

 //CreateNSDatestoholdthestartandenddate
 NSDate*startDate=[[NSDatealloc]init];
 NSDate*endDate=[[NSDatealloc]init];

 //Setpropertiesoftheneweventobject
 event.title=@"Titlefornewevent";
 event.startDate=startDate;
 event.endDate=endDate;
 event.allDay=YES;

 //setevent'scalendartothedefaultcalendar
 [eventsetCalendar:[eventStoredefaultCalendarForNewEvents]];

 //CreateanNSErrorpointer
 NSError*err;

 //Savetheevent
 [eventStoresaveEvent:eventspan:EKSpanThisEventerror:&err];

 //Testforerrors
 if(err==noErr){
 UIAlertView*alert=[[UIAlertViewalloc]
 initWithTitle:@"EventCreated"
 message:@"Howaboutthat?"
 delegate:nil
 cancelButtonTitle:@"Okay"
 otherButtonTitles:nil];
 [alertshow];
 [alertrelease];
 }

 //Releaseobjects
 [startDaterelease];
 [endDaterelease];
 [eventStorerelease];
 }

三：EventKitUI 框架。

在你的app中调用event kit ui

1:导入头文件

 #import<EventKitUI/EventKitUI.h>

@interface CreateEventViewController : UIViewController <EKEventEditViewDelegate>

2：

 -(IBAction)createEvent{
 //Gettheeventstoreobject
 EKEventStore*eventStore=[[EKEventStorealloc]init];

 //CreatetheEditViewController
 EKEventEditViewController*controller=[[EKEventEditViewControlleralloc]init];

 controller.eventStore=eventStore;
 controller.editViewDelegate=self;

 [selfpresentModalViewController:controlleranimated:YES];

 [controllerrelease];

 }

3：delegate method for EKEventEditViewDelegate

 //delegatemethodforEKEventEditViewDelegate
 -(void)eventEditViewController:(EKEventEditViewController*)controllerdidCompleteWithAction:(EKEventEditViewAction)action{
 [selfdismissModalViewControllerAnimated:YES];
 }
