iphone - iOS の UITableView に関する問題 - 前のビューのオーバーラップがスーパービューから削除される

Question

2 つのビュー コントローラーがあり、プロジェクトで sqlite を使用しています。1 つのコントローラーで UITableview を作成して表示し、別のコントローラーで sqlite を介してテーブル セルを削除しています。私の問題は、あるコントローラーから削除操作を行って別のコントローラーに戻るときに、テーブルビューが以前の古いビューと重なってしまうことです。テーブルビューを削除して再作成しました。問題は解決しません。どんな助けでも大歓迎です。スクリーンショットを添付しました。

// create cell
