나는 스티커를 보낼 수있는 채팅 앱을 제작 중이다. 지금까지 내가 한 것은 스티커보기에서 스티커를 살짝 누르면 선택한 스티커가 대화방에 즉시 전송됩니다. 이제는 스티커를 탭하면 나타나는 stickerPreviewView를 추가하라는 메시지가 나타 났고 선택한 스티커는 사용자 응답을 기다리는 stickerPreviewView에 표시됩니다. 사용자가 선택한 스티커 (스티커 이미지가있는 UIButton)를 탭하면 대화방으로 전송됩니다. 내 질문은 채팅방에 스티커를 보내는 방법을 주로 보여주는 관련 코드 아래에있는 방법을 수행하는 방법입니다.미리보기 하위보기에서 선택한 스티커 (이미지)를 어떻게 표시합니까?
