你可以取消已经排定的通知,并计算在取消的通知发射之前的剩余时间,从而安排新的通知。

取消当地通知的使用<代码>cancel Localnottification: of the UIApplication instance, 您可使用 [UIApplication shareApplication]。

我认为......你可以修改排定的通知(说明当地通知)......

Once you have created an instance of UILocalNotification, you schedule it using one of two methods of the UIApplication class: scheduleLocalNotification: or presentLocalNotificationNow:. The former method use the fire date to schedule delivery; the latter method presents the notification immediately, regardless of the value of fireDate. You can cancel specific or all local notifications by calling cancelLocalNotification: or cancelAllLocalNotifications, respectively.

So you can cancel the notification and then schedule it again using scheduleLocalNotification

Note: Prior to iOS 4.2, this property was a read-only method. A setter method has been added and the method has been converted to a read-write property. When you set this property, UILocalNotification replaces all existing notifications by calling cancelLocalNotification: and then calling scheduleLocalNotification: for each new notification.
