我正在进行日历活动，开始日期为2015年2月2日，结束日期为2015年2月6日，我有两个时间上午8:00和下午9:00，这些时间是从带有UIDatePickerModeTime的UIDatePicker中选择的。
根据事件的开始日期，警报/提醒将在两个时间点之后被触发。用户可以使用DatePicker按照自己的意愿更改时间。
如果我将它们添加到事件中，那么它的开始日期仅显示为
快讯，
星期一，2月2日，上午8:00
星期一，2月2日，晚上9点
但是当我转到日历并选择Feb3时，警报也显示为
快讯，
星期一，2月2日，上午8:00
星期一，2月2日，晚上9点
//而不是
快讯，
星期一，2月3日，上午8:00
星期一，2月3日，晚上9点
它会在2月2日至2月6日的上午8点和晚上9点开火吗？还有我需要根据我的要求修改以进行解雇..
这是我到目前为止尝试的代码..
event.alarms = [[NSArray alloc] initWithObjects:[EKAlarm alarmWithAbsoluteDate:pickerFirstAlarm.date],[EKAlarm alarmWithAbsoluteDate:pickerSecondAlarm.date], nil];
是否使用EKAlarm的alarmWithRelativeOffset进行上述处理..
我需要在开始和结束日期的不同闹钟时间发出提醒/闹钟......
任何想法/建议将不胜感激..
在此先感谢..！

是的，我们可以为一个事件添加多个警报。根据你知道如何添加事件我将在此处仅为警报提供代码。我有快速的代码：
if startingDate.isLaterThan(NSDate()) {
let alarm1 = EKAlarm(absoluteDate: startingDate)
let alarm2 = EKAlarm(absoluteDate: endingDate)
event.alarms = [alarm1,alarm2]
} else if endingDate.isLaterThan(NSDate()) {
event.addAlarm(EKAlarm(absoluteDate: endingDate))
}
在此代码中，我需要在开始和结束时发出两个警报，因此我添加了两个警报，但您可以在需要的时间添加多个警报。并且比较时间大于当前时间。对于日期和时间操作，我使用了日期工具。 https://github.com/MatthewYork/DateTools。您可以根据需要轻松将其转换为Objective C.
