ios - データ エンコーディングをネストできますか?

Question

ターン制の Game Center ゲームに取り組んでいます。既に encodeWithEncoder と initWithEncoder を記述したカスタム クラスをエンコードしようとしています。アンパックしない他の小さなカスタム オブジェクトの 2 つの配列を除いて、これらは正常に動作するようです。私の質問は、これらのクラスのカスタム encodeWithEncoder および initWithEncoder メソッドを少し作成し、それらを NSCoding に準拠させた場合、それらもアンパックされるのでしょうか? または、そのようなエンコーディングをネストすることは許可されていませんか? つまり、配列 f Hands と Plays の配列を持つ Game というオブジェクトがあります。それらに NSCoding を実装した場合、それらも解凍できますか?
