オートコンプリート用にUITextView接続されているがあります。UITableView
問題は、テーブルの表示が適切にフォーマットされていないことです。これに関して次の問題があります。
詳細が順番に並んでいません（例：aを押すと、単語が最初から表示されないので、好きなように表示されます）。
txtファイルに3種類の単語があります（Apple、A pple、A.ppleなど）。私のテーブルでは、A ppleとA.ppleのみが表示されますが、Appleではなく文字「Ap」で検索を開始すると、「A P」と書くまではAppleが表示され、単語の表示は停止します。
誰かが私にそれをどうするか教えてもらえますか？
参考までに私のコードを見つけてください：
すべてのコードを投稿して申し訳ありませんが、うまくいかなかったことがわからないのでやっています!!!
