title: Check if a specific UITableViewCell is visible in a UITableView
body: <p>I have a <code>UITableView</code> and some <code>UITableViewCells</code> which i have created manually via the <em>Interface Builder</em>. I've assigned each cell an <code>outlet</code>, and im connecting them to the <code>UITableView</code> in the <code>CellForRowAtIndexPath</code> method. In this method, I use the <code>switch(case)</code> method to make specific cells appear in the <code>UITableView</code>, depends on the case.</p>
  
  <p>Now, I want to find a specific cell and check if he is exists within the <code>UITableView</code>. I use the method: <code>UITableView.visibleCells</code> to get an array of the cells in the table view. My question is - how can i check if a specific cells exists in the array? can I use the outlet that i've assigned to it somehow? -  (The best solution),OR, can I use an identifier and how?</p>
  
  <p>Thanks :)</p>
