title: TTNavigator reboot app inside
body: <p>I'm blocked on a total refresh of my application. I'm using Three20 framework and TTNavigator.
  At some moment I would like to remove and release all my views and viewcontroller (so have a blank screen) and then alloc them again. But I don't know how te do that. In my didFinishLaunchingWithOptions method I'm just doing this :</p>
  
  <pre><code>TTNavigator* navigator = [TTNavigator navigator];
  navigator.persistenceMode = TTNavigatorPersistenceModeNone;
  navigator.delegate = self;
  navigator.window = self.window;
  
  TTURLMap* map = navigator.URLMap;
  [map from:@"cc://home" toSharedViewController:[HomeViewController class]];
  [map from:@"cc://pictures" toViewController:[PicturesViewController class]];
  </code></pre>
  
  <p>I really don't know how to completely reboot my views and viewcontrollers.
  Thanks !</p>
