이 응용 프로그램을 개발하려고하는데 정말 힘들었습니다. 이미지 필터 역할을하는 UIScrollViews 집합을로드하려면 UISegmentedControl을 사용하려고합니다.UISegmentedControl 및 switch 문 관련 문제
UIScrollViews에 큰 문제가있는 것을 제외하면 (이유는 새 세그먼트가 각 세그먼트에서 개별적으로 만들어 짐), 세그먼트 1을 클릭하면 모든 6 개의 UIScrollViews가로드되고 첫 번째 스크롤 만 허용됩니다. 마지막 세그먼트 만 선택하면 UIScrollView가로드됩니다 ...
나는 정말 어떤 제안이 좋지 않은지 알지 못하므로 어떤 제안이 좋을 것입니다!
정말 감사합니다,
