title: Refresh a tab in xcode?
body: <p>Is there a way to refresh a tab's content in XCode?  I'm setting a tab as follows:         [[dappDelegate tabBarController] setSelectedIndex:1];</p>
  
  <p>However, when I try and do it from a different screen, the same tab screen is still selected.  Is there a way to have the tab completely reload the data?</p>
  
  <p>Thanks, Graeme.</p>
