我正在按照这篇文章和M Penades'的答案构建VoIP通知演示。我能够使用
有没有关于如何接收这样的通知的想法？
didRegisterUserNotificationSettings注册通知，并可以从didUpdatePushCredentials获取VoIP令牌。
但是，当我使用houston模拟向我的设备发送通知时，我可以从控制台得到1 push notification sent successfully的消息，但在设备端没有任何操作或日志。看起来didReceiveIncomingPushWithPayload从未被调用。
P.S. 我正在使用Xcode 7.3，iPhone 6(iOS 9.3)和iPad Mini(iOS 9.3)进行开发。分发Ad Hoc ipa以供安装。
这里发布了代码。

gateway.sandbox.push.apple.com（用于开发）改成了gateway.push.apple.com（用于生产环境，我认为对于VoIP推送，这是唯一的选项）。最终我收到了推送消息。 - Shongsu
