如果其他人正在寻找Java中的APNs库，我们在RelayRides刚刚发布了Pushy （ http://relayrides.github.io/pushy/ ）。它做的一些事情与其他两个竞争者（如异步网络IO）不同，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，因此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!

编辑：要明确，Pushy是免费的开源（麻省理工学院许可证）。

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