저는 scrollview 내의 뷰에 서식을 생성하고 있습니다. 그것은 두 개의 textField와 하나의 textView를 포함합니다. 나는 온라인 리소스 (like this one)의 일부 코드를 함께 엮어서 textField가보기에 너무 낮거나 키보드에 의해 방해받는 경우 스크롤 업하도록했습니다. 문제는 textViews에서 작동하지 않는 것입니다.키보드 위로 스크롤하려면 scrollview를 트리거하는 textview를 얻으려면 어떻게해야합니까?
textViews가 동일한 동작을 유발하지 않는 이유를 이해하기 위해 최선을 다했지만 실제로 도움이 될 수 있습니다.
