Macos 获取用户'；s NSUserNotificationCenter

我正在开发一个接收推送通知的Mac应用程序，我希望保持徽章号与用户通知中心中的消息数同步

NSMutableArray *allNotifications = [NSMutableArray array];
[allNotifications addObjectsFromArray:[[NSUserNotificationCenter defaultUserNotificationCenter] deliveredNotifications]];
[allNotifications addObjectsFromArray:[[NSUserNotificationCenter defaultUserNotificationCenter] scheduledNotifications]];

当我轮询NSUserNotificationCenter的已传递和计划通知时，我收到0个对象，尽管我的通知中心中有2条可见消息

NSMutableArray *allNotifications = [NSMutableArray array];
[allNotifications addObjectsFromArray:[[NSUserNotificationCenter defaultUserNotificationCenter] deliveredNotifications]];
[allNotifications addObjectsFromArray:[[NSUserNotificationCenter defaultUserNotificationCenter] scheduledNotifications]];

是否有不同的推送通知通知中心
