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)];
- }
- }
