Xcode で Tabbed Style Application を開発しました。私は合併症に遭遇しました。
私は自分の進歩に満足していますが、Pic 2 または Scene 2 または SelectedCellViewController.m では、下の Pic1 または Scene1 のようにすべてのテーブル セルを表示したくありません。1 つのテーブル セルと関連するテーブル セルを表示して、Pic 3 または Scene 3 にリンクしたいだけです。
Pic 1 または Scene 1 で表のセルを選択すると、選択した色の写真が表示され、写真の下にいくつかの情報が含まれます。Pic 2 または Scene 2 で、写真の下に複数のテーブル セルがあることがわかります。関連するテーブル セルのみを表示したいので、より大きなバージョンが表示されます。機能は既にコーディングしていますが、Pic 2 またはシーン 2 の残りのセルを削除する方法がわかりません。
これを行う方法がわかりません。どんな助けでも大歓迎です。
