title: Add cell to bottom of UITableView in iOS
body: <p>I am using xcode 4.2 with storyboard to create an iphone app.</p>
  
  <p>When I press the edit button in the top right corner I would like to have the options to delete the existing rows and see the extra cell (with the green '+' icon) at the top which would allow me to add a new cell.</p>
  
  <p>I have an array which is being populated in the <code>viewDidLoad</code> method using CoreData</p>
  
  <p>I have enabled the settings button </p>
  
  <pre><code>self.navigationItem.rightBarButtonItem = self.editButtonItem;
  </code></pre>
  
  <p>And implemented the method</p>
  
  <pre><code>- (void)tableView:(UITableView *)tableView commitEditingStyle:   
            (UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:
                     (NSIndexPath *)indexPath
  {
      if (editingStyle == UITableViewCellEditingStyleDelete) {
          // removing a cell from my array and db here... 
      }   
      else if (editingStyle == UITableViewCellEditingStyleInsert) {
          // adding a cell to my array and db here...
      }   
  }
  </code></pre>
  
  <p>I realise I need to add the cell at some point which I can then edit but it isn't clear to me where and I am unable to find a explanation on the internet.</p>
