TABLE VIEW WITH A NAVIGATION BAR - How to bring the Edit functionality
===

I am facing a problem, i have a tab application in which i made the second controller as a navigation controller and just drag and dropped a table view over this.

My table is working fine with all the elements coming in from the database. 

My problem is that i want a edit button when clicked,the table goes into the editing mode and  would allow me to delete rows from the table. I am not able to understand how can i do that i tried this 


    - (void)viewDidLoad
    {
        
          self.navigationItem.rightBarButtonItem = self.editButtonItem;
        
        
          
        [super viewDidLoad];

It brings a edit button on the right side of the navigation controller but when i click it doesn't changes the table in editing mode.


I know i have to implement this method but i am not getting what to write in this

    - (void)setEditing:(BOOL)editing animated:(BOOL)animated {
       
    }
    
Everywhere on other forums i find written tableview ----- , what is this table view is it a instance for the UITableView class ?

 Help me out in the code stuff 
Please
