Question

I have an editable tableView. when i click on the bar button the table becomes editable (a delete button will appear in front of each cell).

When i also slide a cell in the tableview, the delete button gets displayed. I need to know the method that gets executed when i slide to the cell to delete the record of that cell.

I am hoping to change the Edit barbutton to done when the user slides the cell. So how can i do this programatically.

Sorry and i don’t have any code to demonstrate.

This is the line you need to add in viewDidLoad to add edit button which gets converted to Done when you touch it.

self.navigationItem.leftBarButtonItem = self.editButtonItem;

This is the description for editButtonItem:
Returns a bar button item that toggles its title and associated state between Edit and Done.

This is the DataSource method which gets called when you Click Edit

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

if (editingStyle == UITableViewCellEditingStyleDelete)
{

    // Delete code goes here. This is from Core data sample code to delete record. You can implement your own code here.

    NSManagedObjectContext *context = [fetchedResultsController managedObjectContext];
    [context deleteObject:[fetchedResultsController objectAtIndexPath:indexPath]];

    NSError *error;
    if (![context save:&error]) {
        // Update to handle the error appropriately.
        NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
        exit(-1);  // Fail
    }

 }   

}

I hope this helps.
