iOS能不能用代码添加一个日历事件

我看在mail和webView里有日期显示，就可以点击然后出来一个actionsheet，让用户选择创建一个日历事件。
那在程序里有没有这种接口？有没有可能，我通过程序去创建一个日历事件？系统那个ActionSheet，不是我说啊，太难看了。。。

Check EKEvent out

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];
