读取接收和发送的网络流量字节 [英] Read network traffic bytes received and sent

问题描述

在Objective-C中获取网络流量发送和接收字节的最简单方法是什么?

What is the easiest way to get the network traffic sent and received bytes in Objective-C?

推荐答案

这并不容易，它来自C语言而不是Objective-C，但是您所需的所有信息都存储在由以下方法返回给您的接口地址的ifa_data字段中 getifaddrs(3).您可以在中查看如何访问此示例的示例.源代码到libtop_p_networks_sample函数中的"top"实用程序.

It's not easy, and it's from C not Objective-C, but all the info you need is stored in the ifa_data field of the interface addresses returned to you by getifaddrs(3). You can see one example of how to access this in the source code to the 'top' utility, in the libtop_p_networks_sample function.
