Question

我尝试过NSLog(@"The notifications is \n %@",notification);

并且日志消息是：2013-10-18 12：23：36.010剩余[2433：207]通知是{fire date =（null），时区= Asia / Kolkata（IST）偏移19800，重复间隔= 0，重复计数= UILocalNotificationInfiniteRepeatCount，下次开火日期= 2013年10月18日星期五下午12:23:36印度标准时间}

Answer 1

删除特定通知

[[UIApplication sharedApplication] cancelLocalNotification: notification];

取消所有通知

[[UIApplication sharedApplication] cancelAllLocalNotifications];

Answer 2

您必须删除特定的预定通知，您必须使用以下方法。

[[UIApplication sharedApplication] cancelLocalNotification: notification];

Answer 3

如果返回null，则不返回通知。所以试试这个

方法一：

-(void) scheduleNotificationForDate:(NSDate *)date AlertBody:(NSString *)alertBody ActionButtonTitle:(NSString *)actionButtonTitle NotificationID:(NSString *)notificationID{

    UILocalNotification *localNotification = [[UILocalNotification alloc] init];
    localNotification.fireDate = date;
    localNotification.timeZone = [NSTimeZone localTimeZone];
    localNotification.alertBody = alertBody;
    localNotification.alertAction = actionButtonTitle;
    localNotification.soundName = @"yourSound.wav";

    NSDictionary *infoDict = [NSDictionary dictionaryWithObject:notificationID forKey:notificationID];
    localNotification.userInfo = infoDict;

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}

方法2：

设置通知后，唯一的编辑方式是取消旧通知并重新创建另一个通知，这样您就可以这样做，搜索现有通知并取消通知。

`for(UILocalNotification *aNotif in [[UIApplication sharedApplication] scheduledLocalNotifications]) 
{
        if([[aNotif.userInfo objectForKey:@"id"] isEqualToString:nId])
 {
            [[UIApplication sharedApplication]cancelLocalNotification:aNotif];
        }
    }`

如何永久删除n UILocalNotification？
