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];
}
