iOS 7.1.2では、プログラムでUITableViewのセルの高さをプログラム的に調整しようとしています（悲しいことに、それが求められました）。 7以降のすべてのiOSバージョンには問題はありませんが、高さが1のUITableViewディスプレイです。iOS 7.1.2のUITableViewセルの高さ
ここは私のコードです（私は文字通りXcodeのデザインインターフェイスを嫌い、 AutoLayoutを使用します）。 アイデア

どのようにプログラムで制約を追加しますか？ （私はプログラム的に制約を避けるために試しましたが、もしそれが唯一の方法であれば...） – nightslit
私はカスタムUITableViewCellを作成することを提案します –
派生uiclassesを作成する方法へのリンクはありますか？私はプリンシペにあまり精通していない。 – nightslit
