title: How to reset data in previous view controller?
body: <p>I am using multiple view controllers associated with a corresponding tab.</p>
  
  <p>I need to be able to move from  tab2 to  tab1 and to initialize my previous view controller associated with tab1 just as if I had open the tab for the  first time when app launches. However, it does not initialize it like I expect when I switch tabs. This is what I have tried:.
  In my view controller1, I have table data that has navigation to another ViewController. I applied changes to view will disappear but no result.    </p>
  
  <pre><code>-(void)viewWillDisappear:(BOOL)animated  
  {  
            appDelegate.select = nil;        
            [tableCat reloadData];  
             NSLog(@"hello");  
  }
  </code></pre>
  
  <p>Can any one please help me?</p>
