title: Overriding UIBarButtons' functions in the tableView
body: <p>is there a way to override UIBarButtons' functions in the tableView?</p>
  
  <pre><code>- (IBAction)addNewBook:(UIBarButtonItem *)sender {
  
      [self performSegueWithIdentifier:@"addNewBook" sender:self];
  
  }
  
  - (IBAction)myBooks:(UIBarButtonItem *)sender {
      [self performSegueWithIdentifier:@"myBooks" sender:self];
  }
  </code></pre>
  
  <p>I made new actions for these two <code>UIBarButtons</code> (in Table View) and also tried adding segues to go to new viewControllers when these buttons are pressed, but these <code>UIBarButtons</code> already have pre-determined functions - right one's function is to add and the left is to delete. Is there a way to override these functions - so I could get the segues that I want to happen instead of deleting and adding things in the list?</p>
