회전 후 iPhone 크기가 올바르지 않음

Question

모든 장치에서 실행해야하는 iOS 앱을 만들고 있습니다. 슬라이드 쇼를 만들 때 각 장치에 대한 이미지를 갖고 싶지 않았습니다. 나는 이미지를 생성하는 메소드를 생성한다. 배경 이미지, 메인 싱크 이미지, UILabels 및 Scale 2 개를 적절하게 사용합니다. 모든 장치의 세로 방향에서 완벽하게 작동합니다. iPad에서는 풍경이 필요합니다. 회전 할 때 이미지가 늘어나 기 때문에 문제가 발생합니다. 나는 내 시야 범위에 무슨 일이 일어나고 있는지 잘 모르겠습니다. 죄송합니다. 코드가 너무 오래되었습니다.

보기의 프레임은 제대로 아직 viewDidLoad 방법으로 설정되지 않았습니다. 프레임 크기 관련 코드를 viewWillAppear: 메소드로 이동하는 것이 더 정확할 것입니다. 프레임의 크기는 viewWillAppear: 또는 viewDidAppear: 방법에서 정확합니다. 그런 다음 첫 번째 모양에서만 이미지를 생성하려면 boolean 변수를 유지해야 할 수 있습니다.
