iOS获取流量参考

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. 2 

倒入库：

 

SystemConfiguration.framework

 

 

加入头文件：

 

#include <ifaddrs.h>
#include <sys/socket.h>
#include <net/if.h>

    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);
}

 

 

 主要方法就是上面的，然后在你想要知道的结果的地方调用就ok了。

 

[self checkNetworkflow];

 

 

结果：

当然你也可以只统计3G/GPRS流量统计 或者 WIFI流量统计。
