【中文标题】如何向多个设备（iOS）发送推送通知？【英文标题】：How to send a push notification to more than one device (iOS)? 【发布时间】：2012-12-07 15:05:05 【问题描述】：我正在尝试优化我服务器上的推送通知。现在我一个一个地发送那些（带有一个旧图书馆），这需要一段时间（4小时）。
我重构了我的服务以发送带有大量设备令牌的通知（现在我尝试批量处理 500 个令牌）。为此，我正在使用Redth/PushSharp 库。我关注了sample code，然后我对其进行了调整以将通知发送到多个设备令牌。
PushService service = new PushService();
//Wire up the events
service.Events.OnDeviceSubscriptionExpired += new PushSharp.Common.ChannelEvents.DeviceSubscriptionExpired(Events_OnDeviceSubscriptionExpired);
service.Events.OnDeviceSubscriptionIdChanged += new PushSharp.Common.ChannelEvents.DeviceSubscriptionIdChanged(Events_OnDeviceSubscriptionIdChanged);
service.Events.OnChannelException += new PushSharp.Common.ChannelEvents.ChannelExceptionDelegate(Events_OnChannelException);
service.Events.OnNotificationSendFailure += new PushSharp.Common.ChannelEvents.NotificationSendFailureDelegate(Events_OnNotificationSendFailure);
service.Events.OnNotificationSent += new PushSharp.Common.ChannelEvents.NotificationSentDelegate(Events_OnNotificationSent);
service.Events.OnChannelCreated += new PushSharp.Common.ChannelEvents.ChannelCreatedDelegate(Events_OnChannelCreated);
service.Events.OnChannelDestroyed += new PushSharp.Common.ChannelEvents.ChannelDestroyedDelegate(Events_OnChannelDestroyed);
//Configure and start ApplePushNotificationService
string p12Filename = ...
string p12FilePassword = ...
var appleCert = File.ReadAllBytes(p12Filename);
service.StartApplePushService(new ApplePushChannelSettings(true, appleCert, p12FilePassword));
var appleNotification = NotificationFactory.Apple();
foreach (var itemToProcess in itemsToProcess)
itemToProcess.NotificationDateTime = DateTime.Now;
mobile.SubmitChanges();
string deviceToken = GetCleanDeviceToken(itemToProcess.MobileDevice.PushNotificationIdentifier);
appleNotification.ForDeviceToken(deviceToken);
service.QueueNotification(appleNotification
.WithAlert(itemsToProcess[0].MobileDeviceNotificationText.Text)
.WithSound("default")
.WithBadge(0)
.WithCustomItem("View", itemsToProcess[0].Value.ToString()));
//Stop and wait for the queues to drains
service.StopAllServices(true);
然后我尝试向 2 台设备发送 3 条通知。只有第一个设备得到了它们（问题与设备无关，因为我分别尝试了它们）。 紧接着在PushChannelBase class 中抛出一个 OperationCanceledException。所以我不知道怎么了。有什么想法吗？
【问题讨论】：
嗨。这可以在单个请求中将单个推送消息发送到多个设备。我进行了研发并实现了代码，并在 5-10 台设备上进行了测试。 【参考方案1】：您应该为每个要处理的项目排队单独的通知。 无法在单个通知上设置多个设备令牌。 OperationCanceledException 将会发生，因为您这样做了。

假设
-
您有有效的生产和开发证书
您已在数据库中存储了多个设备令牌
您有来自数据库的通知
您正在使用PushSharp 库

【讨论】：
有没有一种方法可以在没有 for each 循环的情况下向多个设备发送推送通知？比如批量推送？一下子.. 这会进行批量推送，for each 循环只是将设备添加到推送队列中。我在生产中使用它并且像魅力一样工作:) 嗨。这可以在单个请求中将单个推送消息发送到多个设备。我进行了研发并实现了代码，并在 5-10 台设备上进行了测试。 @V.J.你能解释一下你是怎么做到的吗？截至目前（2021 年 7 月），没有已知的 APNS 接口。解释你是如何做到的（不使用某种循环）。以上是关于如何向多个设备（iOS）发送推送通知？的主要内容，如果未能解决你的问题，请参考以下文章
