私はiOSプログラミング（およびプログラミング全般）が初めてです。Apple が提供する Birdsighting の例 (http://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/SecondiOSAppTutorial/Introduction/Introduction.html) に基づいて iPhone アプリを作成しようとしています。違いは、AddWorkout TableView Controller で Body Building のワークアウト (Birdsightings の代わりに) を作成し、ワークアウトをマスター TableView Controller に渡し、そこからワークアウトのセルを選択することで、マスターの 1 つは、そのワークアウトのイベントを筋帯ごとに表示します。次に、筋帯セルを選択し、その筋帯のワークアウトのすべての相対パラメーター (エクササイズの種類、重量、シリーズ番号など) を含む DetailView コントローラーをプッシュします。
問題は、2 番目の TableView Controller (MuscleBandViewController) で新しいレコードを渡すことができないため、detailViewController にもプッシュできないことです。なにか提案を？私は今まで 1 週間立ち往生しています (下手な英語で申し訳ありません: 私はイタリア人です)。 ここに私の DataController.h コードがあります:
