iOS调试检测及越狱检测

 if ([self isJailBreak] || [self isJailBreak2] || [self isJailBreak3]) {
        [SVProgressHUD showInfoWithStatus:@"该设备已越狱，请谨慎使用！"];
        [self performSelector:@selector(dismiss) withObject:nil afterDelay:1.5f];
    }
    [self checkDebuggerAction];
    [NSTimer scheduledTimerWithTimeInterval:60 target:self selector:@selector(checkDebuggerAction) userInfo:nil repeats:YES];

/*******************************************越狱检测防范****************************************/
-(void)checkDebuggerAction{
    if (checkDebugger()) {
        exit(0);
    }
}

bool checkDebugger(){
    //控制码
    int name[4];//放字节码-查询信息
    name[0] = CTL_KERN;//内核查看
    name[1] = KERN_PROC;//查询进程
    name[2] = KERN_PROC_PID; //通过进程id查进程
    name[3] = getpid();//拿到自己进程的id
    //查询结果
    struct kinfo_proc info;//进程查询信息结果
    size_t info_size = sizeof(info);//结构体大小
    int error = sysctl(name, sizeof(name)/sizeof(*name), &info, &info_size, 0, 0);
    assert(error == 0);//0就是没有错误
    
    //结果解析 p_flag的第12位为1就是有调试
    //p_flag 与 P_TRACED =0 就是有调试
    return ((info.kp_proc.p_flag & P_TRACED) !=0);
