Question

我正在尝试使用EventKit.framework在iPhone日历中保存事件。它保存完美，但我想将警报设置为“NONE”，但默认情况下需要'30分钟'作为警报。我怎么解决这个问题？这是我在iPhone日历中保存事件的代码

if ([appDelegate.objEvent.event_alert intValue]==0) {
        alarm1 = [EKAlarm alarmWithRelativeOffset:0];
    }
    else if ([appDelegate.objEvent.event_alert intValue]==1) {
        alarm1 = [EKAlarm alarmWithRelativeOffset:-5];
    }
    else if ([appDelegate.objEvent.event_alert intValue]==2) {
        alarm1 = [EKAlarm alarmWithRelativeOffset:-300];
    }
    else if ([appDelegate.objEvent.event_alert intValue]==3) {
        alarm1 = [EKAlarm alarmWithRelativeOffset:-900];
    }
    else if ([appDelegate.objEvent.event_alert intValue]==4) {
        alarm1 = [EKAlarm alarmWithRelativeOffset:-1800];
    }
    else if ([appDelegate.objEvent.event_alert intValue]==5) {
        alarm1 = [EKAlarm alarmWithRelativeOffset:-3600];
    }
    else if ([appDelegate.objEvent.event_alert intValue]==6) {
        alarm1 = [EKAlarm alarmWithRelativeOffset:-7200];
    }
    else if ([appDelegate.objEvent.event_alert intValue]==7) {
        alarm1 = [EKAlarm alarmWithRelativeOffset:-86400];
    }
    else if ([appDelegate.objEvent.event_alert intValue]==8) {//B4 2 days
        alarm1 = [EKAlarm alarmWithRelativeOffset:-172800];
    }

    NSMutableArray *myAlarmsArray = [[NSMutableArray alloc] init];

//    [myAlarmsArray addObject:alarm1];

//    event.alarms = myAlarmsArray;
//    [myAlarmsArray release];

    if ([appDelegate.objEvent.event_alert intValue]!=0)
    {
        [myAlarmsArray addObject:alarm1];
        event.alarms = myAlarmsArray;
    }
    else
    {
//        [myAlarmsArray addObject:nil];
//        event.alarms = nil;
    }

根据文档，如果您想要触发警报，正如您所说的那样，我认为您的意思是在事件发生的确切时间触发，您将使用以下代码

[EKAlarm alarmWithAbsoluteDate:date];
