iOS获取设备流量使用情况 iPhone Data Usage Tracking/Monitoring

感谢 西可韦 分享。

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)

和一个应用"瓦力流量仪"类似.

瓦力流量仪的核心代码也就是这一段吧!

需要引入

 

#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];
