xcodeの初心者なので、ここで学んでいます。これについては完全に間違っているかもしれませんが、これが私のシナリオです。ナビゲーションコントローラーに移動するボタンを備えたオープニングビューコントローラーのストーリーボードがあります。これにより、テーブルビューを使用してmysqlデータベースからエンターテイメントのリストがロードされます（これは正常に機能しています）。詳細ビューですが、何も起こっていません。デバッガーにエラーはありません。私は何を間違っていますか、またはこれについて間違った方法で行っていますか。問題は、didSelectRowAtIndexPath が行われている ENTERTAILMENTLISTING.M のセクションに関係していると思います。これまでのすべてを以下に含めました。
