我希望在我的闹钟应用程序中有重复功能，我无法做到。任何人都可以帮助我..比如伪代码或告诉怎么做，或者一些教程等。
我的闹钟还没有在正确的时间调用，它有时会延迟一段时间50秒，哈哈。应该做些什么。
这是我的代码到目前为止我所做的......

使用此代码可能对你有帮助...
EKEventStore *eventStore = [[EKEventStore alloc] init];
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
event.title = @"EVENT TITLE";
NSDateFormatter* df = [[NSDateFormatter alloc] init];
[df setDateFormat:@"MM/dd/yyyy"];
event.startDate = [df dateFromString:@"your selected date"];
NSLog(@"start date is %@",event.startDate);
event.endDate = [[NSDate alloc] initWithTimeInterval:600 sinceDate:event.startDate];
//NSLog(@"end date %@",event.endDate);
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
//NSLog(@"events are %@",event);
//NSLog(@"events are %@",eventStore);
NSError *err;
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
