UITableViewControllerユーザーがUIButtonナビゲーションバーでaを押し、データ（姓名）を入力すると、コントローラーがこのデータを新しいに配置できるようにするを作成しようとしていますUITableViewCell。私はこれに約1週間取り組んできましたが、一見無限の問題があります。ウォークスルーを見つけるのに役立たずにどこでも検索したので、誰かが私をそれを通して案内してくれることを大いに感謝します。
私はこれまでに次のものを持っています：

私が試したさまざまな方法の数はかなり確かです。それはいくつかの異なる方法の大きな混合物です。私はiOSプログラミングに本当に慣れていないので、うまくいけばそれは回収可能です：P
