ios - 关闭已经传送的 UILocalNotification？

Question

这有可能吗？ UIApplication's scheduledLocalNotifications 似乎没有返回已经发送到用户通知中心的通知，所以我认为这可能是设计使然，但我找不到任何有据可查的证据。

有人知道吗？

谢谢!

编辑:发现这个:

You can cancel a specific scheduled notification by calling cancelLocalNotification: on the application object, and you can cancel all scheduled notifications by calling cancelAllLocalNotifications. Both of these methods also programmatically dismiss a currently

但是，如果 scheduledLocalNotifications 没有给我已发送的通知，我如何获得对已发送通知的引用？

编辑 2:

这是我在注册一些通知后尝试做的事情:

UIApplication *app = [UIApplication sharedApplication];

for (UILocalNotification *localNotification in app.scheduledLocalNotifications) 
{
     if (someCondition) {
            [app cancelLocalNotification:localNotification];
        }
     }
}

问题是，一旦它们被交付，它们就不再处于“scheduledLocalNotifications”中。

您可以通过将新创建的通知添加到您自己的 NSMutableArray 通知并检查该数组而不是 app.scheduledLocalNotifications 来解决此问题。像这样:

将 NSMutableArray 添加到您的 Viewcontrollers .h 文件中:

NSMutableArray *currentNotifications;

在启动 ViewController 时启动它

currentNotifications = [[NSMutableArray alloc] init];

发起通知时，也将其添加到您的数组中:

UILocalNotification *notification = [[UILocalNotification alloc] init];
...
[currentNotifications addObject:notification];
[[UIApplication sharedApplication] presentLocalNotificationNow:notification];

稍后当您想要取消该通知时，请改为在您的数组中查找它。同时将它从你的数组中删除:

for (UILocalNotification *notification in currentNotifications) {
    if (someCondition) {
        [[UIApplication sharedApplication] cancelLocalNotification:notification];
        [currentNotifications removeObject:notification];
    }
}
