ios - 不完全な実装警告とビルドエラー

Question

私はxcodeの初心者です。1時間試していますが、できませんでした。どうすれば修正できますか？やることリストを作ろうとしています。同じコードが他のビューコントローラでも機能します。コードをコピーしてlongに貼り付けました。修正したところ、このエラーが発生しました。よろしくお願いします。

申し訳ありません。これは私の誤りです。 http://d.pr/i/s40r

不完全な実装とは、通常、ファイルでいくつかのメソッドを宣言したが、.hファイルにすべての実装を書き込んでいないことを意味し.mます。これらの実装をすでに作成していると思われる場合は、メソッドのシグネチャが両方のファイルでまったく同じであることを確認してください。

また、を宣言しtableView2:didSelectRowAtIndexPath:ます。おそらくここで必要なのは、デリゲートメソッドtableView:didSelectRowAtIndexPath:（no 2）を宣言し、そのメソッド内でどのテーブルビューがメッセージを送信しているかを確認することです。コードに実装が表示されないため、エラーの原因となっているのはそのメソッドである可能性があります（すばやく確認したので、実際に存在する可能性があります）。
