如何识别ios sdk中的特定通知

Question

实际上正在开发一个警报项目， 现在我对本地通知有疑问。我如何识别特定通知。 我们甚至无法将标签设置为本地通知，那么我如何区分它们。

示例：

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];

现在我要删除第二个通知，我该怎么做... 请帮我.. 提前致谢..

Answer 1

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

就像您现在可以针对第二个要求执行类似的操作

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

            NSLog(@"This is notification 1");
        }

，即对于删除部分，当通知被识别为 n1 或 n2 时，您是否要删除通知，那么在这种情况下，您可以修改上面的代码并添加此

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

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


        }

代码，将上面的代码放置为根据您的方便
