title: webView causing lag in tableview
body: <p>I'm working on a project. I've implemented expandable cell , I have some information on the cell and when I click it it expands showing a description.
  Im loading the description in a <code>UIWebView</code> as I'm taking it in <code>html</code> format from <code>JSON</code>.</p>
  
  <p>What I'm having trouble is that the scroll in <code>UITableView</code> is lagging, and Im 99% sure it is the <code>UIWebView</code> causing the problem as I have other tableviews as well with non-expandable cells , and they're scrolling all smooth.</p>
  
  <p>I think I might solve the problem by not letting the table at the beginning load the <code>html</code> content , only loading it on the Didselect method for each cell I select.</p>
  
  <p>But I'm having a hard time accomplishing this.Is there anyway I can load the <code>UIWebView</code> only for 1 specific cell (in this case only the cell I click).
  Any help is appreciated. 
  If u think there's another way to solve this problem feel free to give suggestions.</p>
  
  <p>Thanks in advance</p>
  
  <p>PS: I've looked at the expandable cell tutorial for <code>swift</code> in <code>youtube</code> and made more or less the same.</p>
