IOS到达率统计
当前IOS到达状态并不准确，调用APNs接口成功，即认为到达成功、展示成功 在IOS 10之后，可以通过扩展统计到真实的到达，此方案提供给需要精确状态的业务方
0.1. 原理
IOS10开始，无论客户端是否活着，都可以在push展示前修改push的内容，如标题内容，下载图片等。此接口需要服务端传mutable-content=1，并且客户端实现扩展。
利用此方案，可以在扩展中调用http接口，向服务端上报该push客户端已收到，服务端利用此状态做数据统计
注意：无论app是前台还是后台，都会调用扩展，但是在扩展中无法判断当前的前后台状态，所以此状态为到达，此方案无法统计展示（ios系统，app前台时无法展示push）。
0.2. 如何使用？
1、联系我们对你们的AppId配置使用启用真实到达率的统计，即配置所有的push都下发mutable-content=1和其他安全相关参数 2、客户端push扩展中代码实现，如下：
