iOS 14 获取设备信息(归因)

iOS 14后，idfa的获取被限制的死死地，各个广告商无法通过之前的idfa来归因了。被苹果爸爸这么一搞，行业内开始整合自己的归因方式。会需要很多其他的参数上报给服务器。以下整理主要参数的获取方式：

1.1 设备启动时间

static time_t bootSecTime(){
     struct timeval boottime;
     size_t len = sizeof(boottime);
     int mib[2] = { CTL_KERN, KERN_BOOTTIME };
     if( sysctl(mib, 2, &boottime, &len, NULL, 0) < 0 )
     {
return 0; }
     return boottime.tv_sec;
 }
 +(NSString *)bootTimeInSec
 {
     return [NSString stringWithFormat:@"%ld",bootSecTime()];
 }

1.2 国家

+(NSString *)countryCode
 {
     NSLocale *locale = [NSLocale currentLocale];
     NSString *countryCode = [locale objectForKey:NSLocaleCountryCode];
     return countryCode;
}

1.3 语言

  +(NSString *)language {
     NSString *language;
     NSLocale *locale = [NSLocale currentLocale];
     if ([[NSLocale preferredLanguages] count] > 0) {
         language = [[NSLocale preferredLanguages]objectAtIndex:0];
     } else {
         language = [locale objectForKey:NSLocaleLanguageCode];
     }
     return language;
 }

1.4 设备名称

+(NSString *)deviceName
 {
     if ([[[UIDevice currentDevice] name] length] == 0) {
         return nil;
}
     return [CAIDMD5Util md5HexDigest:[[UIDevice currentDevice] name]];
 }

1.5 系统版本

+(NSString *)systemVersion
 {
     return [[UIDevice currentDevice] systemVersion];
 }

1.6 设备Machine

  +(NSString *)machine
 {
     NSString *machine = getSystemHardwareByName(SIDFAMachine);
     return machine == nil ? @"" : machine;
 }
 static const char *SIDFAMachine =     "hw.machine";
 static NSString *getSystemHardwareByName(const char *typeSpecifier) {
     size_t size;
     sysctlbyname(typeSpecifier, NULL, &size, NULL, 0);
     char *answer = malloc(size);
     sysctlbyname(typeSpecifier, answer, &size, NULL, 0);
     NSString *results = [NSString stringWithUTF8String:answer];
     free(answer);
     return results;
}

1.7 运营商

         , self] UTF8String], NULL);
     });
     __block NSString *  carr = nil;
     dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);
     dispatch_async(_queue, ^(){
         CTTelephonyNetworkInfo *info = [[CTTelephonyNetworkInfo alloc] init];
         CTCarrier *carrier = nil;
         if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 12.1) {
             if ([info respondsToSelector:@selector(serviceSubscriberCellularProviders)]) {
 #pragma clang diagnostic push

                if (countryCode && [countryCode isEqualToString:@"460"] && networkCode

                    if ([networkCode isEqualToString:@"04"]) { carr= @"中国卫通"; }
                    if ([networkCode isEqualToString:@"20"]) { carr= @"中国铁通"; }
                }else {
                    carr = [carrier.carrierName copy];
                }
            }
         if (carr.length <= 0) { carr =  @"unknown"; }
        dispatch_semaphore_signal(semaphore);
     });
    dispatch_time_t  t = dispatch_time(DISPATCH_TIME_NOW, 0.5* NSEC_PER_SEC);
 
    dispatch_semaphore_wait(semaphore, t);
        return [carr copy];
    #endif
