사용자가 아래의 방법으로 반복적 인 충돌을 경험하고 있습니다. 오류는 항상 [lbl sizeToFit] (lbl 변수가 다시 초기화되고 재사용 됨) 중 하나에서 발생합니다. 제 이해에는 문제가 발생하지 않아야합니다.IOS8 - [UIlabel sizeToFit]이 (가) EXC_BAD_ACCESS KERN_INVALID_ADDRESS의 충돌을 발생시킵니다.
이러한 충돌은 iOS8에서만 발생합니다 (동일한 방법이 ios7에서 아무런 문제없이 오랫동안 사용되었습니다). 나는이 자기 자신을 재현 할 수 없었다. 현재, 내 유일한 단서는 'sizeToFit'사과 문서에서이다 : 어떤 경우 것 말이다
, 뷰가 수퍼가없는 경우,이 화면의 경계의 크기 자체를 할 수있다. 따라서, 주어진 뷰가 부모 뷰의 크기를 정하도록하려면이 메소드를 호출하기 전에 뷰를 부모 뷰에 추가해야합니다.
그러나이 방법으로 메모리가 불량하게 생성되는 것을 볼 수 없습니다.
