1.3G/GPRS流量统计

int getGprs3GFlowIOBytes(){    struct ifaddrs *ifa_list = 0, *ifa;    if (getifaddrs(&ifa_list) == -1)    {        return 0;    }     uint32_t iBytes = 0;    uint32_t oBytes = 0;     for (ifa = ifa_list; ifa; ifa = ifa->ifa_next)    {        if (AF_LINK != ifa->ifa_addr->sa_family)            continue;         if (!(ifa->ifa_flags & IFF_UP) && !(ifa->ifa_flags & IFF_RUNNING))            continue;         if (ifa->ifa_data == 0)            continue;         if (!strcmp(ifa->ifa_name, "pdp_ip0"))        {            struct if_data *if_data = (struct if_data *)ifa->ifa_data;             iBytes += if_data->ifi_ibytes;            oBytes += if_data->ifi_obytes;NSLog(@"%s :iBytes is %d, oBytes is %d",  ifa->ifa_name, iBytes, oBytes);        }    }    freeifaddrs(ifa_list); return iBytes + oBytes;}

返回的结果为byte

2.WIFI流量统计功能

- (long long int)getInterfaceBytes{    struct ifaddrs *ifa_list = 0, *ifa;    if (getifaddrs(&ifa_list) == -1)    {        return 0;    }     uint32_t iBytes = 0;    uint32_t oBytes = 0;     for (ifa = ifa_list; ifa; ifa = ifa->ifa_next)    {        if (AF_LINK != ifa->ifa_addr->sa_family)            continue;         if (!(ifa->ifa_flags & IFF_UP) && !(ifa->ifa_flags & IFF_RUNNING))            continue;         if (ifa->ifa_data == 0)            continue;         /* Not a loopback device. */        if (strncmp(ifa->ifa_name, "lo", 2))        {            struct if_data *if_data = (struct if_data *)ifa->ifa_data;             iBytes += if_data->ifi_ibytes;            oBytes += if_data->ifi_obytes; //            NSLog(@"%s :iBytes is %d, oBytes is %d",//                  ifa->ifa_name, iBytes, oBytes);        }    }    freeifaddrs(ifa_list);     return iBytes+oBytes;}

以上获取的数据可以通过以下方式进行单位转换

NSString *bytesToAvaiUnit(int bytes){if(bytes < 1024)// B{return [NSString stringWithFormat:@"%dB", bytes];}else if(bytes >= 1024 && bytes < 1024 * 1024)// KB{return [NSString stringWithFormat:@"%.1fKB", (double)bytes / 1024];}else if(bytes >= 1024 * 1024 && bytes < 1024 * 1024 * 1024)// MB{return [NSString stringWithFormat:@"%.2fMB", (double)bytes / (1024 * 1024)];}else// GB{return [NSString stringWithFormat:@"%.3fGB", (double)bytes / (1024 * 1024 * 1024)];}}
