私のアプリでは、2つのアクションシートを実行するオプションが必要な領域が1つあります。 1つのオプションに投票するためにTableViewの行に触れると、3つの選択肢、サムズアップ、サムダウン、または提案された日付を表示します。サムネイルをクリックすると、利用可能な日付を持つ別のアクションシートが表示されます。これで2枚目のシートがポップアップしますが、コードself dismissViewControllerのおかげで自動的に解除されます。どのように私がこれをより良くすることができるかに関するどんな考えですか？UIAlertControllerアクションシートをトリガーするアクションシート
