How can I delete selected row from UITableView?

change Table to Edit mode and delete Rows inside a normal ViewController

I want to delete selected row from tableView. I want to provide the functionality to the user to delete the row when he slips or flicks his finger on the row. I know the editing style which provides a circular red button with -ve sign on it.

I have tried this code:

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


[tableView beginUpdates];    
if (editingStyle == UITableViewCellEditingStyleDelete) {
    // Do whatever data deletion you need to do...
    // Delete the row from the data source
    [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath, nil] withRowAnimation:UITableViewRowAnimationTop];      
}       
[tableView endUpdates];
[tableView reloadData];
}

I get the delete button but when I click it SIGABRT Error is there.

Try like below lines:

[bookmarks removeObjectAtIndex:indexPath.row];
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath, nil] withRowAnimation:UITableViewRowAnimationFade];

bookmarks is my array name that I load on table view cell you should give your array name in place of this.

After removing the table row delete the corresponding index dataSource from your dataSource to table.and then reload table again.

    [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
 [dataArray removeObjectAtIndex:indexPath.row];
  [tableView reloadData];

just replace the Code

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle==UITableViewCellEditingStyleDelete)
    { 
        [dataArray removeObjectAtIndex:indexPath.row];
    }


    [tableView reloadData];
}
