我目前正在构建一个类来处理我的 iOS 版 Unity3D 游戏的通知。但是当我使用UnityEngine.iOS.NotificationServices.CancelLocalNotification (nt);时，预定的通知没有任何反应。
有人可以帮助指导如何使这项工作吗？
作为替代方案，我可以使用UnityEngine.iOS.NotificationServices.CancelAllLocalNotifications，但这会不那么优雅。
我在 iphone 6S 上使用 Unity 2017.2.0f3 和 iOS 11.2.1。
public void UpdateMorningNotifications()
{
// Get all current scheduled morning notifications in a list. if they are type morning. erase them.
UnityEngine.iOS.LocalNotification[] scheduledNotifications = UnityEngine.iOS.NotificationServices.scheduledLocalNotifications;
Debug.Log ("NotificationScheduler/UpdateMorningNotifications - number of scheduledNotifications = " + scheduledNotifications.Length);
foreach (UnityEngine.iOS.LocalNotification nt in scheduledNotifications)
{
Debug.Log ("NotificationScheduler/UpdateMorningNotifications - clearing notification, type is " + nt.userInfo["type"] );
if (nt.userInfo ["type"] == "morning")
{
Debug.Log ("Its a morning nt, lets get rid of it!");
UnityEngine.iOS.NotificationServices.CancelLocalNotification (nt);
Debug.Log ("NotificationScheduler/UpdateMorningNotifications - clearing notification: " + nt.alertBody);
}
}
// building, and adding notifications to notificationservices.
DateTime fireDate = DateTime.Today;
int summedInterval = 0;
// fill up the morning timings list.
foreach (int interval in MorningNotificationDayInterVals)
{
// adding new interval to firedate
summedInterval = summedInterval + interval;
fireDate = fireDate.AddDays (summedInterval);
// if weekend fire at 10AM else 8 AM
if (fireDate.DayOfWeek.ToString() == "Saturday" || fireDate.DayOfWeek.ToString() == "Sunday") {
fireDate.AddHours (10);
} else {
fireDate.AddHours(8);
}
//generate notification with random title and the timing and add it to the batch.
int morningTitleIndex = UnityEngine.Random.Range(0,morningTitles.Length);
// generating a new notification.
notification = GenerateNotification (morningTitles[morningTitleIndex], fireDate, "morning");
// adding the notification to the batch.
notificationBatch.Add (notification);
Debug.Log("NotificationScheduler/UpdateMorningNotifications: Length of notificationBatch = " + notificationBatch.Count);
}
// Adding notifications to notificationsservices
AddNotificationBatchToNotificationServices (notificationBatch);
}
