title: how to reduce number of tab bar items shown on iPad
body: <p>I have a split View Controller iPad app.  Its a port of a iPhone version that relied heavily on the tab bar.  Since you cannot put a split view controller into a tab bar (or at least shouldn't, or so I've read) I settled on a design where the tabbar controller is inside the detail view controller of the split view controller.</p>
  
  <p>This works fine.  However, the tabbar is showing 8 tabs rather than 5 like on the iPhone.  This makes for an incredibly cramped tab bar.  </p>
  
  <p>I know on the iPhone the 4+more is unchangable.  Does anyone know if there's a way to make the iPad only show 4 icons or 5 icons on the tabbar?
