私はステッカーを送ることができるチャットアプリに取り組んでいます。私がこれまで行ってきたことは、ステッカービューでステッカーをタップすると、選択したステッカーがすぐにチャットルームに送られます。今私はステッカーをタップするとポップアップするstickerPreviewViewを追加するように求められ、選択されたステッカーは最初にユーザーの応答を待っているstickerPreviewViewに表示されます。ユーザーが選択したステッカーをタップすると（そのステッカーイメージの付いたUIButton）、チャットルームに送信されます。私の質問は、私がチャットルームにステッカーを送る方法に主に示す関連コードの下で与えられたことをどうやって行うことができるかです。プレビューサブビューで選択したステッカー（画像）を表示するにはどうすればよいですか？

それは部屋をチャットするステッカーを送信する方法を参照してくださいChatRoomVCをチェック - 私が送信する方法を複製しようとしているところStickerPreviewViewへのステッカーですが、それほど簡単ではありません。私はここで助けが必要です。
