외부 API로부터 사용자를 끌어 오는 '평가'기능을 내 앱에서 만드는 중입니다. 그런 다음 섹션 이름 (사용자 이름)과 UISlider가 포함 된 셀을 추가하는 TableView를 만듭니다.UserID와 함께 UISliders에서 값 가져 오기 (사용자를 섹션 번호로 연결)
내가하려는 일은 UISliders의 사용자 ID와 함께 사용자 데이터 섹션을 수집하여 API에 POST 작업을 호출하여 등급 데이터도 보낼 수 있도록하는 것입니다.
여기 내가 가지고있는 코드입니다 : (공식적으로, 스위프트와 처음으로, 코멘트 나이 작업을 수행하는 방법을 알아 내려고 노력하고있다). 어떤 아이디어?
