您可在第4号现场发出通知,使用当地识别器。

以下是一些样本代码:

UILocalNotification *noti = [[UILocalNotification alloc] init];
noti.fireDate = someDate;
noti.alertBody = someText;
noti.alertAction = nil;
noti.soundName = UILocalNotificationDefaultSoundName;
[[UIApplication sharedApplication] scheduleLocalNotification:noti];
[noti release];

确保该日期尽可能接近[NSDate Day],因此该日期似乎已经过时。
