如何将推送通知发送到多个设备（iOS）？

我试图优化我的服务器上的推送通知。现在我把它们一个接一个送出去（有一个老图书馆），需要一段时间（4小时）。如何将推送通知发送到多个设备（iOS）？

我重构了我的服务来发送一个带有很多设备标记的通知（现在我尝试了一批500个标记）。为此，我使用Redth/PushSharp库。我跟着sample code然后我调整它发送通知给几个设备令牌。

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);

然后我试着发送3个通知给2个设备。只有第一个设备得到了它们（问题与设备无关，因为我试图单独使用它们）。之后，在PushChannelBase class中抛出了OperationCanceledException。所以我不知道什么是错的。任何想法？

嗨。这可以通过单个请求将单个推送消息发送到多个设备。我进行了研发并实施了代码，并使用5-10个设备进行了测试。 –

您应该为要处理的每个项目排队一个单独的通知。
无法在单个通知上设置多个设备令牌。 OperationCanceledException将会发生，因为你这样做。

例如：控制台C＃应用程序

这是假设

你有效的生产和开发证书
您已在数据库中存储多个设备令牌
你有一个通知来自您的数据库
