Instead of using viewDidLoad use -(void) viewWillAppear:(BOOL)animated

Remember that you'll be returning to the view so clear/update anything that's not applicable.

E.g;

-(void) viewWillAppear:(BOOL)animated
{
  [super viewWillAppear:animated];  

  // reload the table   
  [self.tableView reloadData];
}
