title: iOS7 UITableViewStyleGrouped section header font style name?
body: <p>All the answers I've seen so far are basically for pre-iOS7 (using <code>systemFontStyle</code> or <code>boldSystemFontStyle</code>).  That doesn't correspond to the default capitalized section title font in <code>UITableViewStyleGrouped</code>.</p>
  
  <p>I've had to implement the <code>UITableViewDelegate</code> method that return the custom section header view and want to know the font Apple uses to capitalize section titles.</p>
