4 つの異なるビュー コントローラーに 4 つのビデオがあり、アプリがランダムにクラッシュします。通常、最初にクリックしたもの (それが何であれ) が機能し、ボタンをクリックして他のビデオを再生すると、アプリがクラッシュします。通常、どちらを最初にクリックしてもかまいません。アプリの動作がおかしい。これが私が得るエラーコードです：

残りのビュー コントローラは基本的に同じですが、もちろん IBActions と moviePlayers の名前が異なります。どんなアドバイスでも大歓迎です！ありがとう！

次の名前のメソッドが表示されません。

- (void) moviePlayBackDidFinish:(NSNotification*)notification

ShoreViewControllerカット アンド ペーストしたコード スニペットのいずれか (ただし、いずれかのビュー コントローラーが実際に " " オブジェクトであるかどうかは明らかではありません)

コードに存在しない場合は、「インスタンスに送信された認識されないセレクター」のクラッシュが説明されます。
