This function gets executed
Code:
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPat

but This function is not getting called.... and the minus (-) button doesn't appears
Code:
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath


Code:
// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {
	[super loadView];
	tblSelectedSupplier = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
	//allocate the view
	self.view = tblSelectedSupplier;
	tblSelectedSupplier.delegate = self;
	tblSelectedSupplier.dataSource = self;
	
	//Set the title
	self.navigationItem.title = @"Selected Supplier";
	
	self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Save" style:UIBarButtonItemStyleBordered target:self action:@selector(save_selSupplier:)]autorelease];
	
	[self setEditing:YES animated:YES];
}


- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
	NSLog(@"will appear contacts");
    [tblSelectedSupplier reloadData];
	
}

-(IBAction)save_selSupplier:(id)sender{
	

}

        [tblSelectedSupplier deleteRowsAtIndexPaths:indexPaths

    }
	

}

//exclude rows from being edited

        [[cell textLabel] setFont:titleFont];
	}
	
	KeyValue *keyval = [selectedSuppList objectAtIndex:indexPath.row];//[[Dictionary getarrySelSupplier] objectAtIndex:0];
	//[supplierlist objectAtIndex:indexPath.row];
	cell.textLabel.text = keyval._value;

	
	return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
	NSLog(@"didSelectRowAtIndexPath");
}

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
	
	return 45;
}
 
A couple of questions:

  • When do you expect that method to be called?
  • What happens if you swipe right in a cell?

  • When do you expect that method to be called?
    On the view load
  • What happens if you swipe right in a cell?
    The delete button appears

Thanks its done
i replaced
Code:
[self setEditing:YES animated:YES];
with this
Code:
[tblSelectedSupplier setEditing:YES animated:YES];

By following code i thought tblSelectedSupplier will act as self, but it doesn't seems so....
self.view = tblSelectedSupplier;
