크래시 로그 이해 - KERN_PROTECTION_FAILURE

Question

나는 응용 프로그램을 사용하는 동안 다른 시점에 예기치 않게 발생하는 충돌을 해결하려고합니다. 필자는 무엇이 될 수 있는지에 대해 잃어 버렸기 때문에 어떤 도움을 주시면 감사하겠습니다. 필요할 때 ARC로 변환하여 @AutoReleasePool을 사용했지만 여전히 이걸 때때로 받고 있습니다 ...

최선의 추측을 볼 코드가 없으면 메소드가 직접 또는 i 자체를 재귀 적으로 호출합니다. 직접적으로 종료에 이르지 못합니다. 아마도 NSDictionary 또는 NSArray에는 해당 참조가 다시 그 안에 들어가는 항목이있을 수 있습니다.

가능한 경우 코드에서 어디에서 발생했는지 생각해 보려면 Xcode에서 실행을 일시 중지하십시오.
