前言
在开发中，有的时候为了统计用户信息、下发广告，服务器端往往需要手机用户设备及app的各种信息，这些信息的获取可以根据不同的设备或者app、系统版本来提供不同的功能或更好的用户体验，或者让开发者能更好的分析用户的问题原因。
下面讲述一下各种信息的获取方式：
一行代码就搞定的统一来！

广告位标识符：在同一个设备上的所有app都会取到相同的值，是苹果专门给各广告提供商用来追踪用户而设的，用户可以在 设置|隐私|广告追踪里重置此id的值，或限制此id的使用，故此id有可能会取不到值，但好在apple默认是允许追踪的，而且一般用户都不知道有这么个设置，所以基本上用来监测推广效果，是戳戳有余了

nsstring *idfa = [[[asidentifiermanager sharedmanager] advertisingidentifier] uuidstring];nslog(@"广告位标识符idfa-->%@", idfa); |
uuid是universally unique identifier的缩写，中文意思是通用唯一识别码。它是让分布式系统中的所有元素，都能有唯一的辨识资讯，而不需要透过中央控制端来做辨识资讯的指 定。这样，每个人都可以建立不与其它人冲突的 uuid。在此情况下，就不需考虑数据库建立时的名称重复问题。苹果公司建议使用uuid为应用生成唯一标识字符串。
