title: How can I push a new view controller onto a different nav controllers stack and switch to it?
body: <p>I have a Tab Bar Controller created in Interface Builder</p>
  
  <p>Within the Tab Bar are 4 Navigation Controllers.</p>
  
  <p>Each controller functions separately and perfectly (yay!)</p>
  
  <p>What I need to be able to do is a push a view controller onto a different nav controllers stack and switch the focus onto the appropriate tab bar item (so that the user moves sideways (to a different tab) and up (to a new view) at the same time).</p>
  
  <p>This is my first time working with a tab bar controller, and while it's been simple to this point, figuring this out is giving me fits.  Any tips you can toss my way would be much appreciated.</p>
