上一篇说到ios10 开启限制广告跟踪之后 获取的idfa就是一串000000，网上大神很快就给吾等屌丝搬砖者带来了福音SimulateIDFA
(源文件下载地址:http://files.cnblogs.com/files/slc-lover/SimulateIDFA.zip)
SimulateIDFA 是根据一堆设备信息（每个app获取的值都是一样的）生成的一个MD5值。用于标志不同设备。
使用时
#import "SimulateIDFA.h"
NSString *simulateIDFA = [SimulateIDFA createSimulateIDFA];
NSLog(@"获取到的simulateIDFA 是 %@",simulateIDFA);
导入CoreTelephony.framework
SimulateIDFA.h文件：
SimulateIDFA.m文件：
#import <UIKit/UIKit.h>
#import "SimulateIDFA.h"
#import <sys/sysctl.h>
