今天，2021年3月18日，突然收到了之前从未遇到过的拒审邮件，邮件原文如下：

邮件的内容主要在于这一句：We found that your app collects user and device information to create a unique identifier for the user’s device.（我们发现您的应用程序收集用户和设备信息，以便为用户的设备创建唯一标识符。）

事件起因为来自于苹果iOS14IDFA隐私政策，即，在iOS14系统后，应用程序在获取相关的权限时，会有弹窗出现提醒用户是否进行授权，如果用户未授权，广告商将无法访问IDFA，进而将对所有基于idfa的广告业带来巨大影响。

于是，来自中国的互联网巨头和广告协会趁势推出了对此的应对方案，即CAID，并于今年开始在业内大力推广。CAID，作为第三方的监测技术，其实现的前提必须是广告主和媒体方都要同时接入CAID，形成约定好的标准以达到跟踪的目的。

因此，显然，CAID是为绕开IDFA标识而生，且目前还未得到苹果的认可。据中国广告协会表示，该解决方案将不会反对苹果的隐私政策，正在与苹果积极沟通。

但是，通过这个加了CAID的应用收到拒审邮件来看，苹果的态度已经非常清楚了，这是中国广告协助的坑！
