내용을 내 레이블에 추가 할 때 크기를 조정하고 scrollview를 세로로 스크롤 할 수 있도록하는 데 문제가 있습니다. 내 계층 구조는 다음과 같습니다내용에 따라 uiscrollview 크기 조정
내 생각이 보이지만 :
그래서 나는 텍스트를 얻을 때 시작에 내 코드의 내용으로 라벨을 작성하고 싶습니다 API 호출로부터. 그러나 테스트를 위해 일부 lorem ipsum 텍스트를 하드 코딩하여 작동하도록했습니다. 따라서 내 컨텐츠가 레이블에 추가되고 UILabels의 크기가 조정되고 레이블이 포함 된 뷰의 크기가 조정됩니다. 라벨의 텍스트가 더 길면 스크롤 할 수 있도록 scrollview 내용의 크기를 조정하는 데 문제가 있습니다. 그것이 내가 텍스트 길이에 따라 내 라벨 및보기 크기 조정을 할 수 있었던 유일한 방법 이었기 때문에 나는 또한 PureLayout을 사용하고
