Question

I have this table on linked to a database with a “Edit” on top-right.
I can delete swiping, but if I press the Edit button nothing happen!
I mean, I wrote a similar call for another table in the same program, and when i press edit, a small “Unlock to delete” appear; then if you press it you can delete the element/row…
not here!

- (void)viewDidLoad
{
    self.title = @"Categorie";
    [super viewDidLoad];
    self.navigationItem.rightBarButtonItem = self.editButtonItem;
    [self.navigationItem setHidesBackButton:YES animated:YES];
    [tableView reloadData];
}

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
    return YES;
}

- (void)tableView:(UITableView *)_tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (editingStyle == UITableViewCellEditingStyleDelete)
    {
        // A lot of code... 
    }
}

You need to tell the tableView to begin editing with setEditing:(BOOL)editing animated:(BOOL)animate

//Init your editBarButton
UIBarButtonItem *editButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(editTable)];

//Init your doneBarButton
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(doneEditing)];

Here’s the a sample action method:

- (void)editTable {
   if (!self.tableView.editing) [self.tableView setEditing:YES animated:YES];
   self.navigationController.rightBarButtonItem = self.doneButton;
}

- (void)doneEditing {
   if (self.tableView.editing) [self.tableView setEditing:NO animated:YES];
   self.navigationController.rightBarButtonItem = self.editButton;
}
