How to reset data in previous view controller?
<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>
