iOS流量监控

http://code4app.com/snippets/one/iOS%E6%B5%81%E9%87%8F%E7%9B%91%E6%8E%A7/5020ba7a6803fae325000000

1.能够检测iOS的WIFI，3G以及GPS的流量。

-(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;

        }

          

        //wifi flow

        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;

        }  

          

        //3G and gprs flow

        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;

        }

    }

    freeifaddrs(ifa_list);    

}

 

2.iOS获取设备流量使用情况，iPhone Data Usage Tracking/Monitoring，获取的是开机后WIFI,3G/GPRS网络下使用流量(仅仅只能获取开机后的)。

 

#include <arpa/inet.h>

#include <net/if.h>

#include <ifaddrs.h>

#include <net/if_dl.h>

 

+ (NSArray *)getDataCounters

{

    BOOL   success;

    struct ifaddrs *addrs;

    const struct ifaddrs *cursor;

    const struct if_data *networkStatisc; 

  

    int WiFiSent = 0;

    int WiFiReceived = 0;

    int WWANSent = 0;

    int WWANReceived = 0;

  

    NSString *name=[[[NSString alloc]init]autorelease];

  

    success = getifaddrs(&addrs;) == 0;

    if (success) 

    {

        cursor = addrs;

        while (cursor != NULL) 

        {

            name=[NSString stringWithFormat:@"%s",cursor->ifa_name];

            NSLog(@"ifa_name %s == %@\n", cursor->ifa_name,name);

            // names of interfaces: en0 is WiFi ,pdp_ip0 is WWAN 

            if (cursor->ifa_addr->sa_family == AF_LINK) 

            {

                if ([name hasPrefix:@"en"]) 

                {

                    networkStatisc = (const struct if_data *) cursor->ifa_data;

                    WiFiSent+=networkStatisc->ifi_obytes;

                    WiFiReceived+=networkStatisc->ifi_ibytes;

                    NSLog(@"WiFiSent %d ==%d",WiFiSent,networkStatisc->ifi_obytes);

                    NSLog(@"WiFiReceived %d ==%d",WiFiReceived,networkStatisc->ifi_ibytes);

                }

                if ([name hasPrefix:@"pdp_ip"]) 

                {

                    networkStatisc = (const struct if_data *) cursor->ifa_data;

                    WWANSent+=networkStatisc->ifi_obytes;

                    WWANReceived+=networkStatisc->ifi_ibytes;

                    NSLog(@"WWANSent %d ==%d",WWANSent,networkStatisc->ifi_obytes);

                    NSLog(@"WWANReceived %d ==%d",WWANReceived,networkStatisc->ifi_ibytes);

                } 

            }

            cursor = cursor->ifa_next;

        }

        freeifaddrs(addrs);

    }       

    return [NSArray arrayWithObjects:[NSNumber numberWithInt:WiFiSent],

         [NSNumber numberWithInt:WiFiReceived],

         [NSNumber numberWithInt:WWANSent],

         [NSNumber numberWithInt:WWANReceived], nil];
