SIGSEGV StoreKit에서 충돌 - 복제 할 수 없습니다.

Question

클라이언트가 기존 앱을 가져 왔으며 크래시 보고서에 대한 Crittercism을 포함한 새 버전을 방금 출시했습니다.

출시 이후, 우리는 아래와 같이 충돌 보고서를로드하고 있습니다. 그 충돌은 SKProductRequest의 대표가 너무 빨리 발표했기 때문에 발생했습니다. 그래서 충돌이 일어나는 이유에 대한 답변을 찾고 있지 않습니다. 이미 StackOverflow에서 다른 곳으로 답변을 받았습니다.

내 문제는 내가 버그를 복제 할 수 없다는 것입니다. 수많은 기기와 iOS의 다른 버전을 사용해 보았습니다. Crittercism에서 충돌은 주로 최신 장치 및 iPhone, iPod 및 iPad의 범위에서 발생합니다. 따라서이 장치는 특정 유형의 장치가 아니지만 계속 발생시킬 수는 없습니다. 나는 Lite 버전을 다운로드했고 거기에서 Full 버전을 구입했습니다. 완벽하게 작동합니다.

내 질문에 그러므로 누군가 내 장치에서 일어날 수 있도록 어떻게 해결할 수 있는지 알 수 있습니까?!

Answer 1

휙휙, 여기에 매우 의심스러운 코드를 게시했습니다. 한 가지로 SYNTHESIZE_SINGLETON_FOR_CLASS()를 사용하면 AppStoreService dealloc 메서드가 호출되지 않으므로 앱에서 메모리 누수가 발생한다는 의미입니다. 또한 productsRequest에서 [릴리스 요청]에 대한 호출은 실제로 매우 이상하게 보입니다. 그러나 SKProductsRequest와 관련된 특정 문제는 SKProductsRequest가 콜백을 호출하기 전에 할당 취소 된 개체 중 하나를 가리키는 대리자와 관련이있는 것으로 보입니다. 이는 위임자 역할을하는 객체가 dealloc 메소드를 호출 할 때 델리게이트를 nil로 설정해야 함을 나타냅니다. 문제를 재현하는 방법은 코드에서 설정 한 정말 이상한 개체 수명 때문에 매우 까다로울 수 있습니다. 자동 회귀 테스트 도구를 사용하는 것이 좋겠지 만, 싱글 톤을 사용하기 때문에 앱의 개체 수명을 확인하는 데에도 도움이 될지 잘 모르겠습니다. What is so bad about singletons?

Answer 2

나는 "귀하의 이론"이 너무 빨리 발표되는 SKProductRequest의 대리인 "이라고 생각합니다. 구매 도중에 응용 프로그램을 종료/종료하려고 했습니까? 샌드 박스 서버가 너무 빠르면 (트랜잭션이 완료되기 직전에 중단 점을 삽입하고 수동으로 앱을 종료하십시오.) 앱이 다시 실행되고 결국 StoreKit에 트랜잭션으로 등록됩니다 위임자는 이전 실행에서 열린 트랜잭션을 가져 와서 몇 가지 디자인 실수를 발견하고 StoreKit 트랜잭션 완료와 관련된 버그를 해결할 수있었습니다.
