title: Using AlamofireImage Inside UITableViewCell
body: <p>I've been reading a lot of <a href="https://stackoverflow.com/questions/16663618/async-image-loading-from-url-inside-a-uitableview-cell-image-changes-to-wrong">answers</a> here saying that by using AlamofireImage helper methods (e.g. <code>af_setImageWithURL()</code>) or any equivalent library, you don't need to worry about cell reusing stuff (Plus, many published tutorials actually just do that). That is to say, I don't have to keep a weak reference to the cell or getting it by using tableView's <code>cellForRowAtIndexPath()</code> method to update its imageView after the background downloading finishes, like what we usually do if request made manually.</p>
  
  <p>First of all, is that true? And if so, how it was done inside the library, cause I tried to trace AlamofireImage's <code>af_setImageWithURL()</code> code, and I cannot find any effort made to make sure we're still working on the same cell we made the request from. Am I missing something?</p>
  
  <p>I am sorry if it sounds stupid, but I am really confused.</p>
