title: Positioning UISwitch in UITableView for iPhone, iPad, and Retina
body: <p>I have a grouped TableView and I've positioned a UISwitch to the right side of the row, just to the left of the ">". For now, I've used an explicit CGRect (no calculated values).</p>
  
  <p>In iPhone 4.2 it is positioned correctly, but of course on iPad 4.2 it's not.</p>
  
  <p>Are there specific ways to calculate positioning that will yield the same relative placement regardless of the device/screen res?
  Or do I just use the screen width, table cell width, etc., and calculate it myself?</p>
