私は大量の8k + Line FeedViewControllerをパックしていましたが、いつでも私は何十ものviewcontrllersを変更しなければならないステータスの外観を含む何かを変更したいので、リファクタリングをMVCタイプの標準に従おうと決めました。これは本当に間違っている.....私はだけではなく、12個のファイルのセルクラスを変更することができるように、私はtableviewcellsに機能のほとんどを入れて、今イム公聴会「あなたはダムあなたの閲覧数を維持すべきか？MVCはIOSのコンテキストでも何を意味しますか？

MVCパターンに固執したいときは、ビューをできるだけダムにしておく必要がありますが、それは正しいことです。最良の場合、ビジネスロジックを含むべきではありません。 – Alex
私は質問にその理論を置くより具体的な質問を読んでください – ChuckKelly
"...ビジネスロジックを含んでいない"は、彼らもビジネス_オブジェクト（モデル）に関する**何も**知ってはいけない**ことを意味します。 'self.StatusLabel.text = self.statusObject.message;'の 'statusObject'がデータ転送オブジェクト以外のものであれば、セルが自分の値を取り出すことはできません。 – Alex
