如何识别ios sdk中的特定通知

实际上正在开发一个报警项目，现在我对本地通知有疑问。 我怎样才能确定一个特定的通知。 我们甚至不能将标签设置为本地通知，那么我怎样才能区分它们。

例：

通知：1

UILocalNotification *localNotification = [[UILocalNotification alloc] init]; localNotification.fireDate = selectedDate; localNotification.alertBody = @"you got work"; localNotification.alertAction = @"Snooze"; localNotification.repeatInterval = NSDayCalendarUnit; localNotification.soundName = UILocalNotificationDefaultSoundName; NSDictionary *infoDict = [NSDictionary dictionaryWithObjectsAndKeys:@"setNotificationForEveryDay", @"key", nil]; localNotification.userInfo = infoDict; [[UIApplication sharedApplication] scheduleLocalNotification:localNotification]; [localNotification release]; 

通知：2，

 UILocalNotification *localNotification = [[UILocalNotification alloc] init]; localNotification.fireDate = another selectedDate; localNotification.alertBody = @"i got work"; localNotification.alertAction = @"Snooze"; localNotification.repeatInterval = NSDayCalendarUnit; localNotification.soundName = UILocalNotificationDefaultSoundName; NSDictionary *infoDict = [NSDictionary dictionaryWithObjectsAndKeys:@"setNotificationForEveryDay", @"key", nil]; localNotification.userInfo = infoDict; [[UIApplication sharedApplication] scheduleLocalNotification:localNotification]; [localNotification release]; 

现在我在情况下删除第二次通知我该怎么做…请帮助我..在此先感谢..

我的猜测是使用userInfo来区分本地通知，这将是一个更好的主意，但为此，您需要设置本地通知的userInfo。

就像你可以做这样的事情

  if（[Your_notification_Object.userInfo valueForKey：@“Key 1”] == @“Object 1”）{

             NSLog（@“This is notification 1”）;
         }

现在为您的第二个要求即删除部分是否要删除通知时，它被确定为n1或n2那么在这种情况下，你可以修改上面的代码，并添加

 if（[Your_notification_Object.userInfo valueForKey：@“Key 1”] == @“Object 1”）{

             NSLog（@“This is notification 1”）;
 [[UIApplication sharedApplication] cancelLocalNotification：Your_notification_Object];


         }

根据您的方便，放置上面的代码
