ビューを2ページ目に遷移させるボタンを取得して、3ページ目の件名に同時にテキストを割り当てようとしています。そこにある件名にテキストを取得する方法は知っていますが、そこにテキストを取得する方法はわかりません。

初心者で分かりにくくてすみません。

コードを見ずに答えるのは難しいですが、試してみます。

ソフトウェア設計の観点から、「3 番目のページ」が 1 番目または 2 番目のページに依存しないことが重要です。その結果、2 番目のページをプッシュするときに、最初のページから必要な情報を提供します。例えば：

最初のページ コード (最小の Ma​​c ではなく、疑似コード):

SecondPageController *secondPage = [[SecondPageController alloc]init];
secondPage.subjectLine = @"Flat Tire";
[self PushViewController:secondPage];

次に、2 番目のページで、3 番目のページに移動するときに:

ThirdPageController *thirdPage = [[ThirdPageController alloc] init];
thirdPage.subjectLine = self.subjectLine;
[self PushViewController:thirdPage];

このようにして、各コントローラーは、その仕事を行うために何を知る必要があるかを認識します。3 番目のコントローラーは、1 番目または 2 番目のコントローラーに依存したり、知ったりする必要はありません。それを作成したもの、そのsubjectLineプロパティを初期化したもの (およびその他に必要なもの) だけです。
