title: Button Displays Under Cells in Custom UITableViewCell
body: <p>I have an app that uses a custom <code>UITableViewCell</code> to display detail information after a user clicks on a given row in a table.  I can't seem to figure out why the "Reply" button located in the cell is inactive and appears behind the table itself.  I can't click on it, select it, or do anything.  I used Interface Builder to add the button rather than programmatically add it.  </p>
  
  <p>I've tried changing a number of things including the cell's class and File's Owner, but can't seem to get the button to be active and working.  I think the button is linked up properly with a connection to a method in the code.</p>

  <p>Here's a minimal, complete example of the code:</p>
