其实在做APNS发送信息的时候，总会有一些信息好象没有收到。所以我就在想是什么问题。
看到这一篇的时候，才感觉可能会是这种原因：
问题四：Push消息丢失
如果客户端偶尔能收到消息，但有丢失，那很有可能是服务器往苹果APNs服务器写入失败、或者写成功后苹果服务器未发送（批量往一堆token发送消息，如果第一个token发送失败，那么苹果不会再给后面同一批的token推送消息）。失败原因可通过向苹果做Feekback查询。

同时觉醒和我说，feekback在这里可以查询一下：http://developer.apple.com/library/mac/#documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html
里面是这么一句：Feedback Service
Sometimes APNs might attempt to deliver notifications for an application on a device, but the device may repeatedly refuse delivery because there is no target application. This often happens when the user has uninstalled the application. In these cases, APNs informs the provider through a feedback service that the provider connects with. The feedback service maintains a list of devices per application for which there were recent, repeated failed attempts to deliver notifications. The provider should obtain this list of devices and stop sending notifications to them. For more on this service, see “The Feedback Service.”
证明还是可以查的嘛 .准备下次慢慢查一下
