title: transition from viewcontroller to tab bar controller with a navigation controller at each tab error
body: <p>Hi I added a prepare for segue code in order to transfer information, however I'm getting an error.</p>
  
  <p>I have a tab bar controller. It has 4 tabs. Each tab has a navigation controller, and a VC as a root view controller.</p>
  
  <p>from tab 1-->nav controller-->VC 1 I need to take a value to tab2-->nav controller --->VC1</p>
  
  <p>(also is the segue connected to the nav controller at tab 2, or the root view at tab 2)
  Thank you in advance</p>
  
  <p>error:customizableViewControllers]: unrecognized selector sent to instance 0xf19bd60
  (but I am going to tab 2 (index 1))?
  where is my error?</p>
  
  <pre><code>    if ([segue.identifier isEqualToString:@"ResultsSegue"])
  
          {
  //the root VC at tab 2
              ResultsIndexViewController*controller=[[ResultsIndexViewController alloc]init];
  
              UITabBarController *tabController = [segue destinationViewController];
              controller = (ResultsIndexViewController*)[[tabController customizableViewControllers]objectAtIndex:1];//crashing here
              controller.resultsArray=[NSMutableArray arrayWithArray:_matchedResultsArray];
  
          }
      }
  </code></pre>
