私はiPadアプリをやっていますが、私はUITabelviewとButtonとUiTextviewを同じ画面に表示しますか？私の仕事は、私がUITableviewでいくつかの行を選択し、ボタンを押すと、テキストがUITextviewに表示されなければならないということです。SQlite3をUITextviewに接続する
私はいくつかの方法を記入しましたが、うまくいきませんでしたが、私はこの仕事を成功裏に完了するために何ができるか教えていただけますか？
あなたの参照のために私のコードを見つけてください...私の問題を説明するのを助けるかもしれません。

私はiPadの開発に新しいですし、ここに打た私を助けてください..
これら3つのクラスの関係は何ですか？ – Ravin
こんにちはRavin：1つはデータベース、テーブルビュー、テキストビュー – makumar
あなたのボタンはどこですか？ –
