앱 시작시 오작동이 발생합니다.

앱이 시작될 때 매우 이상한 충돌이 발생합니다. 내 응용 프로그램은 많은 스레드를 생성합니다 (500 개 이상, 대부분은 PLPreheatItem과 관련이 있습니다. 전체 크래시 로그를 여기에 붙여 넣을 수 없으므로 stackoverflow에 30,000 개의 심볼이 있음).앱 시작시 오작동이 발생합니다.

문제는 내 장치에서 재생할 수 없다는 것입니다. 또한 거의 모든 실행 내 고객을위한 깨끗한 설치에서 발생합니다.

백그라운드 세션과 NSOperationQueue를 동시에 사용하는 NSURLSession을 사용하고 있습니다. 이들은 내가 생각하기에 가장 약한 부분이다.

누군가 내가 발굴해야 할 곳을 제안 할 수 있습니까? 왜냐하면 나는 정말로 무엇을해야할지 모른다.

감사합니다.

좋아, 문제가 해결 된 것 같습니다.

앱을 만들 때 PHCachingImageManager을 작성하고 startCachingImagesForAssets:targetSize:contentMode:options:을 작성했습니다. 사용자가 보유한 모든 iCloud 애셋에 대해이 작업을 수행 했으므로 캐싱 할 애셋이 많은 경우 즉시 모든 캐싱을 시작하십시오.

결과적으로 PHCachingImageManager은 각 자산에 대해 수십 개의 스레드를 직렬로 연속적으로 생성합니다. (나의 고객을 위해 500 이상). 따라서 응용 프로그램의 메모리가 부족합니다.

다음은 사람들이이 문제를 해결할 수있는 방법입니다. How to use PHCachingImageManager

오류 메시지가 잘립니다. 분명히 "커널은 가상 수신에 필요한 메모리를 할당 할 수 없습니다."

아마도 장치가 동시에 처리 할 수있는 최대 스레드 수를 상회하고있을 것입니다. 500 개의 스레드는 앱의 스레드 스택에 대해서만 약 0.5 기가 바이트의 RAM으로 변환되어 힙을 구성하거나 화면의 백업 저장소를 할당하기도합니다. 512MB RAM (iPhone 4S 이하, iPod Touch 5 세대 이하, iPad 2 이하, iPad Mini 1 세대 이전)의 장치에서는 작동 할기도가 없습니다. 그리고 심지어 더 새로운 장치에서, 그것은 끔찍하게 학대입니다.

Apple Photo Framework에서 수행중인 작업에 의해 발생하는 것처럼 보입니다. 많은 수의 그림 또는 메타 데이터에서 메타 데이터를 보는 작업을 수행하는 경우 지연을 추가하거나 그렇게하는 속도를 제한해야합니다. 그 외에도 bugreport.apple.com에서 버그 리포트를 제출하고 최선을 희망하는 것 외에는 할 수있는 일이 없을 수도 있습니다.

앱 시작시 오작동이 발생합니다.
