sqliteデータベースからデータをロードするお気に入りビューがあります。明らかにセルへのエントリをロードします。
お気に入りビュークラスの名前はFavRealです。データベースからエントリを削除し、テーブルビューから削除するアクションを使用して、canEditRowAtIndexPathを有効にしました。それはうまくいきます！また、すべてのエントリを正しく削除する[すべてのお気に入りをクリア]ボタンがあります。
ここで、セルをクリックすると、Details22ビューと呼ばれる別のビューに移動します。このビューでは、選択したセルの詳細を取得し、機能します。
エントリをクリックしてお気に入りビューに戻った後。スワイプジェスチャまたはすべてのボタンをクリアしてエントリを削除しようとした場合。それは機能しません：Sエラーも何もありませんデータベースから削除せず、テーブルビューから即座に削除します。
これが私のコードです。
