当我尝试设置 startDate 和 endDate 时，我不断收到错误消息。我在这里做错了什么？这是我的代码：
EKEventStore *eventStore = [[EKEventStore alloc] init];
EKEvent *newEvent = [EKEvent eventWithEventStore:eventStore];
NSDateFormatter * dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd:HH:mm"];
NSString *fechainicio = @"2011-04-13:22:30";
NSString *fechafin = @"2011-04-14:24:00";
NSDate * date = [[NSDate alloc] init];
date = [dateFormatter dateFromString:fechainicio];
NSDate * date2 = [[NSDate alloc] init];
date2 = [dateFormatter dateFromString:fechafin];
[date2 retain];
[date retain];
[fechainicio retain];
[fechafin retain];
newEvent.title = @"title";
newEvent.startDate = date;
newEvent.endDate = date2;
[newEvent setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
[eventStore saveEvent:newEvent span:EKSpanThisEvent error:&err];
if (err != nil)
{
NSLog(@"error");
}
我当然希望有人能帮助我解决这个错误，这让我发疯了 XD。谢谢。
