CAGradientLayer를 사용하여 내 uButton의 스타일을 지정하고 있습니다. 기본적으로 세 개의 버튼이 셀에 있습니다. 먼저 CAGradientLayer 속성을 설정할 때 잘 동작합니다 (그래디언트를 얻습니다).CALayer의 QuartzCore 관련 문제
그러나 CAGradientLayer를 두 번째 응용 프로그램에 적용하면 두 번째 응용 프로그램에 나타나지만 첫 번째 응용 프로그램에서는 사라집니다. 그리고 제가 3 분의 1로한다면, 그것은 3 분의 2에 나타나고 처음 2 분에서 사라질 것입니다.
UIButton 설정 사이에 CAGradientLayer를 출시하겠습니까?
