iOS-获取设备流量使用数据

 

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)

需要引入

#include <arpa/inet.h>
#include <net/if.h>
#include
#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];
}
