跟踪数据使用情况

我正在尝试跟踪iPhone用户的数据使用情况。

但是我发现我发现这个：

- (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]; 

}

但我怎么能自动做到这一点，每次用户调用Web浏览器我相交包的大小

谢谢

您正在寻找logging或分析

日志logging：只需NSLog或写入数组并定期保存到文件

分析：看看这是一个很好的用户体验跟踪程序
