获取当前iphone设备的流量

通过读取系统网络接口信息，获取当前iphone设备的流量相关信息，统计的是上次开机至今的流量信息.

导入库：SystemConfiguration.framework

加入头文件：

#include <ifaddrs.h>

#include <sys/socket.h>

#include <net/if.h>

代码实现：

-(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)];
　　}
}

//
-(void)checkNetworkflow {

　　struct ifaddrs *ifa_list = 0, *ifa;

　　if (getifaddrs(&ifa_list) == -1)
　　{
　　return;
　　}

　　uint32_t iBytes = 0;

　　uint32_t oBytes = 0;

　　uint32_t allFlow = 0;

　　uint32_t wifiIBytes = 0;

　　uint32_t wifiOBytes = 0;

　　uint32_t wifiFlow = 0;

　　uint32_t wwanIBytes = 0;

　　uint32_t wwanOBytes = 0;

　　uint32_t wwanFlow = 0;

　　struct timeval time ;

　　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.
　　　　// network flow

　　　　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;

　　　　allFlow = iBytes + oBytes;

　　　　time = if_data->ifi_lastchange;

　　　　// NSLog(@"1111===%s :iBytes is %d, oBytes is %d", ifa->ifa_name, iBytes, oBytes);

　　　　}

　　　　 //<span style="font-family: Tahoma, Helvetica, Arial, 宋体, sans-serif; ">WIFI流量统计功能</span>

　　　　if (!strcmp(ifa->ifa_name, "en0"))

　　　　{
　　　　　　struct if_data *if_data = (struct if_data *)ifa->ifa_data;

　　　　　　wifiIBytes += if_data->ifi_ibytes;

　　　　　　wifiOBytes += if_data->ifi_obytes;

　　　　　　wifiFlow = wifiIBytes + wifiOBytes;

　　　　}

　　　　//<span style="font-family: Tahoma, Helvetica, Arial, 宋体, sans-serif; ">3G和GPRS流量统计</span>

　　　　if (!strcmp(ifa->ifa_name, "pdp_ip0"))

　　　　{

　　　　　　struct if_data *if_data = (struct if_data *)ifa->ifa_data;

　　　　　　wwanIBytes += if_data->ifi_ibytes;

　　　　　　wwanOBytes += if_data->ifi_obytes;

　　　　　　wwanFlow = wwanIBytes + wwanOBytes;

　　　　　　//NSLog(@"111122===%s :iBytes is %d, oBytes is %d", ifa->ifa_name, iBytes, oBytes);

　　　　}

　　}

　　freeifaddrs(ifa_list);

　　NSString *changeTime=[NSString stringWithFormat:@"%s",ctime(&time)];
　　NSLog(@"changeTime==%@",changeTime);

　　NSString *receivedBytes= [self bytesToAvaiUnit:iBytes];
　　NSLog(@"receivedBytes==%@",receivedBytes);

　　NSString *sentBytes = [self bytesToAvaiUnit:oBytes];
　　NSLog(@"sentBytes==%@",sentBytes);

　　NSString *networkFlow = [self bytesToAvaiUnit:allFlow];
　　NSLog(@"networkFlow==%@",networkFlow);

　　NSString *wifiReceived = [self bytesToAvaiUnit:wifiIBytes];
　　NSLog(@"wifiReceived==%@",wifiReceived);

　　NSString *wifiSent = [self bytesToAvaiUnit: wifiOBytes];
　　NSLog(@"wifiSent==%@",wifiSent);

　　NSString *wifiBytes = [self bytesToAvaiUnit:wifiFlow];
　　NSLog(@"wifiBytes==%@",wifiBytes);

　　NSString *wwanReceived = [self bytesToAvaiUnit:wwanIBytes];
　　NSLog(@"wwanReceived==%@",wwanReceived);

　　NSString *wwanSent = [self bytesToAvaiUnit:wwanOBytes];
　　NSLog(@"wwanSent==%@",wwanSent);

　　NSString *wwanBytes = [self bytesToAvaiUnit:wwanFlow];
　　NSLog(@"wwanBytes==%@",wwanBytes);
}

然后在你想要知道的结果的地方调用：

　　[self checkNetworkflow];

控制台输出结果如下：

当然你也可以只统计3G/GPRS流量统计或者 WIFI流量统计。

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

    if (getifaddrs(&ifa_list) == -1)
    {
        return 0;
    }
 
    uint32_t iBytes = 0;
    uint32_t oBytes = 0;

        if (strncmp(ifa->ifa_name, "lo", 2))
        {
            struct if_data *if_data = (struct if_data *)ifa->ifa_data;
 
            iBytes += if_data->ifi_ibytes;

//            NSLog(@"%s :iBytes is %d, oBytes is %d",
//                  ifa->ifa_name, iBytes, oBytes);
        }
    }
    freeifaddrs(ifa_list);
 
    return iBytes+oBytes;
}
