我试过了
谷歌开发人员的“在iOS上安装GCM客户端应用程序”。
我的应用程序有安卓版本，服务器成功地向安卓发送推送通知。在iOS中，我可以将消息检索到didrecieveremotenotification函数。打印时如下所示：
aps: {
alert = {
body = tyyy;
title = "2 is going out at 03/24/2016 15:02:48";
};
badge = 2;
sound = default;
}
当应用程序处于前台和后台时，它会收到此消息。当应用程序为后台时，系统托盘中不显示任何内容。
当应用程序终止，服务器发送推送通知时，我什么也没有收到，没有显示任何活动。
我的代码如下。

我有两个问题，
即使应用程序处于终止状态，是否可以接收和显示推送通知？如果是，如何？
我在代码中做错什么了吗？
最佳答案：
这是您的推送通知json？
aps: { "content-available" = 1; }
如果是，则发送无声推送。无提示推送意味着用户不会收到任何可视通知，只调用应用程序的应用程序委托回调。删除内容可用标记并传递消息文本。
如果应用程序在前台，iOS不会显示推送通知，只会调用代理。然后您可以显示警报视图或其他您喜欢的视图。
或者您可以显示：https://github.com/avielg/AGPushNote
关于“用户终止”状态，这里是Apple Doc（用于静默推送）：
