title: ViewDidLoad is not called for the second time Xcode
body: <p>I have a tableViewController from which i navigate to UIViewController. To save the value of indexPath.row I have used an integer and based on that integer action is performed in UIViewController. Problem is that when I press the back button and selects another index of table, It navigates to UIViewContoller but the action performed is the first one. the ViewDidLoad is not called for the second time. 
  here is my code. </p>
  
  <p>TableView Code:</p>
  
  <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
  {
      if (!self.iaRecipieViewController) {
          self.iaRecipieViewController = [[[iRecipieViewController alloc] initWithNibName:@"iRecipieViewController" bundle:nil] autorelease];
      }
      if (indexPath.row == 0) {
          self.iaRecipieViewController.myLableArray =labelSoupArray ;
      }
  
      if (indexPath.row == 1) {
          self.iaRecipieViewController.myLableArray =labelSoupArray ;
      }
  
      if (indexPath.row == 2) {
          self.iaRecipieViewController.myLableArray =labelSoupArray ;
      }
      // custom string is an NSinteger
      self.iaRecipieViewController.customString = indexPath.row;
      NSLog(@"  int  %i",self.iaRecipieViewController.customString);
      NSLog(@"index path %i ", indexPath.row) ;
  
      [self.navigationController pushViewController:iaRecipieViewController animated:YES];
  
      [detailTable reloadData];
  }
  </code></pre>
  
  <p>UIViewController Code. </p>
  
  <pre><code>- (void)viewDidLoad
  {
      [super viewDidLoad];
      // Do any additional setup after loading the view from its nib.
  
      myLabel.text = [self.myLableArray objectAtIndex:customString];
  }
  </code></pre>
