IOS源码开发获取当前的流量信息

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：

[html] view
plaincopy

SystemConfiguration.framework

加入头文件：

[html] view
plaincopy

#include <ifaddrs.h>

#include <sys/socket.h>

#include <net/if.h>

流量统计功能

-(NSString *)bytesToAvaiUnit:(int)bytes

{

if(bytes < 1024) // B

{

return [NSString stringWithFormat:@"%dB", bytes];

}

else if(bytes >= 1024 && bytes < 1024 * 1024) // KB

{

return [NSString stringWithFormat:@"%.1fKB", (double)bytes / 1024];

}

else if(bytes >= 1024 * 1024 && bytes < 1024 * 1024 * 1024) // MB

{

return [NSString stringWithFormat:@"%.2fMB", (double)bytes / (1024 * 1024)];

}

else // GB

{

return [NSString stringWithFormat:@"%.3fGB", (double)bytes / (1024 * 1024 * 1024)];

}

}

-(void)checkNetworkflow{

if (getifaddrs(&ifa_list) == -1)

{

return;

}

uint32_t iBytes = 0;

uint32_t oBytes = 0;

uint32_t allFlow = 0;

uint32_t wifiIBytes = 0;

for (ifa = ifa_list; ifa; ifa = ifa->ifa_next)

{

continue;

{

iBytes += if_data->ifi_ibytes;

oBytes += if_data->ifi_obytes;

allFlow = iBytes + oBytes;

time = if_data->ifi_lastchange;

// NSLog(@"1111===%s :iBytes is %d, oBytes is %d", ifa->ifa_name, iBytes, oBytes);

}

//<span style="font-family: Tahoma, Helvetica, Arial, 宋体, sans-serif; ">WIFI流量统计功能</span>

if (!strcmp(ifa->ifa_name, "en0"))

{

wifiOBytes += if_data->ifi_obytes;

wifiFlow = wifiIBytes + wifiOBytes;

}

//<span style="font-family: Tahoma, Helvetica, Arial, 宋体, sans-serif; ">3G和GPRS流量统计</span>

if (!strcmp(ifa->ifa_name, "pdp_ip0"))

{

//NSLog(@"111122===%s :iBytes is %d, oBytes is %d", ifa->ifa_name, iBytes, oBytes);

}

}

freeifaddrs(ifa_list);

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。

plaincopy

[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。
