【iPhone开发】ios统计流量代码

 #include <ifaddrs.h>
 #include <sys/socket.h>
 #include <net/if.h>

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)];
     }
 }
