body: <p>I've found some questions and answers to remove offset of UITableViews in ios7, namely this one here
   <a href="https://stackoverflow.com/questions/18773239/how-to-fix-uitableview-separator-on-ios-7">How to fix UITableView separator on iOS 7?</a></p>
  
  <p>I was wondering if anyone had come across the correct functions to remove inset margins. Something similar to this answer in objective-c</p>
  
  <pre><code>if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {

  }
  </code></pre>
