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：

SystemConfiguration.framework

加入头文件：

#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)];
	}
}

    NSString *receivedBytes= [self bytesToAvaiUnit:iBytes];
    
    NSLog(@"receivedBytes==%@",receivedBytes);

    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。
