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)];
}
}
