Estou tentando excluir uma linha da minha exibição de tabela e até agora não obtive êxito. Eu continuo recebendo esse erro:

"Finalizando o aplicativo devido à exceção não capturada 'NSInternalInconsistencyException', motivo: 'Atualização inválida: número inválido de linhas na seção 0. O número de linhas contidas em uma seção existente após a atualização (5) deve ser igual ao número de linhas contidas na essa seção antes da atualização (5), mais ou menos o número de linhas inseridas ou excluídas dessa seção (0 inserido, 1 excluído). '"A matriz que eu uso para preencher a exibição da tabela é declarada nessa classe, também i obter meus objetos para minha matriz de um banco de dados sqlite.

O código que eu usei para tentar excluir linhas é o seguinte.

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

if (editingStyle == UITableViewCellEditingStyleDelete) {
    // Delete the row from the data source

    [categoryArray objectAtIndex:indexPath.row];
    [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:YES];

}   
else if (editingStyle == UITableViewCellEditingStyleInsert) {
    // Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view
}   
}

Agora, para as perguntas, espero receber respostas:

-Como posso excluir linhas corretamente?

-Eu enfrentarei a exclusão da linha se for a única que resta no tableView?

-Posso alterar o tableView que é usado no método para ser o UITableView que eu declarei no meu arquivo .h?

Muito Obrigado.
