Simperium에서 처리되지 않은 예외가 발생했습니다.

Question

최신 Simperium 라이브러리로 내 응용 프로그램을 충돌하는 예외가 발생했습니다. 내가 할 수있는 한 모든 것을 설정했지만, 코어 데이터 변경을 시도하고 동기화하려고 할 때마다 예외가 발생합니다. 여기

가 throw되는 예외입니다 :

libc++abi.dylib: terminate called throwing an exception 

내가 오류가 일어나고있는 줄 생각이 하나입니다

 dispatch_sync(dispatch_get_main_queue(), ^{ 
    [__managedObjectContext mergeChangesFromContextDidSaveNotification:notification]; 
}); 

하지만 난 확실히 내 버그로 100 % 아니에요 사냥 :(

누구나 어떤 아이디어를 가지고 위대한 아닌가요?

감사

이 줄 :

당신이 알아야 할 모든 것을 알려줍니다. 응용 프로그램 대리인에게 handleManagedObjectContextChange: 메시지를 보내려고하지만 해당 메서드를 구현하지 않습니다. 따라서 메시지를 보내는 위치를 식별하고 메시지를 보내려는 대상으로 메시지가 실제로 전송되는지 확인해야합니다.

이 답변은 다소 일반적인 것일 수 있지만, 한 줄의 코드 만 제공했음을 알 수 있습니다. 스택 추적의 모양에서 통지를 처리하는 영역을 식별하십시오. 찾고있는 좋은 장소 일 것입니다.
