在EKEvent中将事件的特定日期设置为iCal

标签: ios icalendar ekevent

我是Xcode的初学者,并搜索以下代码,在我的应用内添加一个事件。但该示例仅显示如何使用[[NSDate alloc] init];

设置开始日期和结束日期

我可以获得哪些代码来设置我想要的日期,例如20-12-2012?

感谢您的时间。

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

EKEvent *myEvent  = [EKEvent eventWithEventStore:eventDB];

myEvent.title     = @"New Event";
myEvent.startDate = [[NSDate alloc]init ];

myEvent.endDate   = [[NSDate alloc]init ];
myEvent.allDay = YES;

[myEvent setCalendar:[eventDB defaultCalendarForNewEvents]];

NSError *err;

[eventDB saveEvent:myEvent span:EKSpanThisEvent error:&err]; 


    UIAlertView *alert = [[UIAlertView alloc]
                          initWithTitle:@"Event Created"
                          message:@"Yay!?"
                          delegate:nil
                          cancelButtonTitle:@"Okay"
                          otherButtonTitles:nil];
    [alert show];

正如您所发现的,将NSDate对象设置为非平凡日期完全不重要。

有几种方法可以做到这一点。

1)

查看the documentation for [NSDateFormatter dateFromString:]

<强> 2)

这是设定2012年12月20日的另一种方式。

NSCalendar * gregorian = [NSCalendar currentCalendar];
NSDate *currentDate = [NSDate dateWithTimeIntervalSinceReferenceDate: 0];
NSDateComponents *comps = [[NSDateComponents alloc] init];
[comps setYear: 11]; // 11 years past the reference date of 1-January-2001
[comps setMonth: 11]; // 11 months past January
[comps setDay:19]; // 19 days past the first day of January
NSDate *eventDate = [gregorian dateByAddingComponents:comps toDate:currentDate  options:0];

NSLog( @"event date is %@", [eventDate description] );
[comps release]; // NSDateComponents was explicitly alloc'd & init'd

myEvent.startDate = eventDate;
mtEvent.endDate = eventDate;
