Tracking data usage for network requests using AFNetworking
<p>I am trying to figure out a way to find how much data is sent/received by my requests with AFNetworking. What are some of the best practices to solve this problem?</p>

<p>Example:</p>

<ul>
<li>do a GET to an endpoint <code>fakeapi/downloadlist</code> </li>
<li>I want to know how many bytes were sent to the server and how many bytes were received back.</li>
</ul>

<p>Thanks for your help!</p>
