如果其他人正在寻找 Java 中的 APNs 库，我们 RelayRides 刚刚发布了 Pushy (http://relayrides.github.io/pushy/).它在某些方面与其他两个竞争者不同(例如异步网络 IO)，因此它可以非常快速地发送大量消息.我们实际上也在生产中使用它，所以它由我们的工程师积极维护.享受！

If anybody else is looking for an APNs library in Java, we at RelayRides just released Pushy (http://relayrides.github.io/pushy/). It does some things differently than the other two contenders (like async network IO), so it can send large numbers of messages really quickly. We actually use it in production, too, so it's actively maintained by our engineers. Enjoy!

明确地说，Pushy 是免费和开源的(MIT 许可).

To be clear, Pushy is free and open-source (MIT license).
