💡캘린더의 메모 뷰의 키워드, 리뷰 여부에 따른 메모 Height 변화

이슈1

isHidden 메소드를 이용하여 false로 해도 해당 뷰의 Space는 그대로 남아있었기 때문에 키워드, 리뷰가 없어도 첫 화면처럼 완성이 되지 않았었다.

하지만 StackView를 이용하여 해결했는데, StackView의 특성 상 내부의 Contents가 줄어들면서 StackView전체가 같이 줄어들기 때문에 아래의 코드처럼 Contraints 값을 조정했을 때 원하는 모습대로 뷰가 나올 수 있었다.

/// 키워드, 리뷰의 입력 여부에 따른 메모 뷰 크기 조정
    func memoHeightMode(idx: Int){
        /// 키워드 미입력 시
        if keywordForCV.count == 0 {
            calendarKeywordCollectionView.isHidden = true
            keywordCVTopAnchor.constant = 0
        }else{
            calendarKeywordCollectionView.isHidden = false
            keywordCVTopAnchor.constant = 14
        }
        /// 메모 미입력 시
        if fetchCalendar[idx].review.count < 1 || fetchCalendar[idx].review == "" {
            keywordCVBotAnchor.constant = 0
            memoTextLabel.isHidden = true
        }else{
            keywordCVBotAnchor.constant = 10
            memoTextLabel.isHidden = false
        }
        
        /// 키워드,메모 미입력 시
        if (fetchCalendar[idx].review.count < 1 || fetchCalendar[idx].review == "") && keywordForCV.count == 0  {
            memoBtnTopAnchor.constant = 22
            memoBtn.isHidden = true
        }else{
            memoBtnTopAnchor.constant = 17
            memoBtn.isHidden = false
        }
