一、IDFA&IDFV是什么东东
二、那些年我们见过的名词
三、获取你想要的设备信息
IDFA - Identifier For Advertising（广告标识符）
IDFA 是苹果 iOS 6 开始新增的广告标识符，用于给开发者跟踪广告效果用的，可以简单理解为 iPhone 的设备临时身份证，说是临时身份证是因为它允许用户更换。

IDFA 是目前苹果生态广告交易的主要标识，一般跟广告商交易一个用户后广告商需要给你提供用户的 IDFA 作为凭证，主流的广告平台腾讯广点通、新浪粉丝通对账是基于 IDFA 的。
- 同一设备上的所有App获取到的 IDFA 是相同的
- iOS 用户可以通过（设置程序 -> 通用 -> 还原 -> 还原位置与隐私）更换 IDFA
- iOS 10 系统开始提供禁止广告跟踪功能，用户勾选这个功能后，应用程序将无法读取到设备的 IDFA
获取IDFA
// AdSupport.framework
#import <AdSupport/AdSupport.h>
// 获取IDFA
NSString * IDFA = [[[ASIdentifierManager sharedManager] advertisingIdentifier] UUIDString];
示例：E1D2194B-6C91-4094-8F5B-F7CAE5C50989
开关切换的时候IDFA会变，还原的时候会变，用户重置手机系统的时候也会变。所以在获取IDFA之前可以先进行判断。
// 用户是否限制广告追踪
Boolean on = [[ASIdentifierManager sharedManager] isAdvertisingTrackingEnabled];
NSLog(@"%hhu",on);
IDFV - Identifier For Vendor（应用开发商标识符）
- Vendor -》应用开发商的意思
- 在同一个设备上来自同一个应用开发商的所有App，IDFV的值是相同的
- 不同的应用开发商运行在同一个设备上IDFV值不同
- 如果用户将属于该应用开发商的所有App都卸载，则IDFV的值会被重置，即使再重装此开发商的App，IDFV的值也和之前不同
- 适用于对内：例如分析用户在应用内的行为等
获取IDFV
NSString * IDFV = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
示例：67097426-5C22-4914-87D0-034C77741872
那些年我们见过的名词
1、UDID ，全称是 （Unique Device Identifier），顾名思义，它就是苹果IOS设备的唯一识别码，它由40个字符的字母和数字组成，为了保护用户隐私苹果已经禁止读取这个标识了。
2、UUID，全称是（Universally Unique IDentifier），是基于iOS设备上面某个单个的应用程序，只要用户没有完全删除应用程序，则这个 UUID 在用户使用该应用程序的时候一直保持不变。如果用户删除了这个应用程序，然后再重新安装，那么这个 UUID 已经发生了改变。UUID 不好的地方就是用户删除了你开发的程序以后，基本上你就不可能获取之前的数据了。
// 获取CFUUID
CFUUIDRef cfuuid = CFUUIDCreate(kCFAllocatorDefault);
NSString * cfuuidString = (NSString*)CFBridgingRelease(CFUUIDCreateString(kCFAllocatorDefault,cfuuid));
// 获取NSUUID
NSString * uuid = [[NSUUID UUID] UUIDString];
3、MAC 地址，用来定义网络设备的位置。一个主机会有一个 MAC 地址，MAC 地址是网卡决定的，是固定的，为了保护用户隐私苹果已经禁止读取这个标识了。
4、OpenUDID，不是苹果官方的，是一个替代 UDID 的第三发解决方案， 缺点是如果你完全删除全部带有 OpenUDID SDK 包的 App（比如恢复系统等），那么 OpenUDID 会重新生成，而且和之前的值会不同，相当于新设备；
5、IDFA 广告标示符，适用于对外：例如广告推广，换量等跨应用的用户追踪等。
6、IDFV 来自同一个运营商的应用运行在同一个设备上，此属性的值是相同的；不同的运营商应用运行在同一个设备上值不同。
