0x00：防作弊产品介绍
1.由于IOS系统的不开放性，能获取的信息太少，所在IOS上的防作弊产品可做的功能就相比较于安卓要少很多了。硬件方面主要获取IDFA、IDFV这两个值，软件方面主要获取一些风险APP的名称。
0x01：SDK整体框架
1.该防作弊产品提供SDK形式给开发者调用，当开发者成功集成到APP后，APP启动时就会生成一个唯一的ID值。
2.SDK客户端整体流程如图1所示:
图1
3.服务器返回的ID会存放在系统中，这个ID值用通俗的话说，就是为每台设备注册一个身份证号，它代表了设备。这样一来，如果刷量者通过hook机制来修改IDFA、mac等设备模拟新用户就不起作用了。
0x02：技术细节分析
1.APP启动时会解密会判断本地是否缓存了deviceID值与风险app名单，如果没有就生成一个随机的deviceid然后解密写死在app中的风险文件名单。
2.从服务器获取deviceid值
如果没有缓存ID就生成一个ID，生成随机的deviceID代码如下：
