title: Varying space between table view cell and footer title
body: <p>I have a very basic grouped <code>UITableViewController</code> with <code>UITableViewCellStyleDefault</code> cells with just the <code>textLabel.text</code> set.</p>
  
  <p>Usual suspect methods: <code>numberOfSectionsInTableView</code>, <code>numberOfRowsInSection</code>, <code>cellForRowAtIndexPath</code>.</p>
  
  <p>Only 'fancy' thing I have is <code>titleForFooterInSection</code> which just returns <code>NSStrings</code> of varying length.</p>
  
  <p>I just noticed that the space between a cell and the footer text is proportional to the number of lines in the footer text.  It's not a little bit either: on the iPhone 6 plus screenshot if ranges from 52 (2 line footer) to 95 (8 line footer) pixels.</p>
  
  <p>This looks crappy. Does anyone know if this is a 'feature'? Is there an easy way to correct this (other than creating my own footer views)?</p>
  
  <p>Running iOS 9.3.2.</p>
  
  <p>Same thing happens in Apple's own apps, for example Settings > Control Centre.</p>
