Zrobiłem pewne dalsze dochodzenie w ślad stosu i znalazł kod Subresourceloader tutaj (https://webkit.googlesource.com/WebKit/+/master/Source/WebCore/loader/SubresourceLoader.cpp).

Domyślam się, że m_resource jest NULL w tym miejscu oznaczonym (****) powodując katastrofę:

void SubresourceLoader::didReceiveResponse(const ResourceResponse& response) 
{ 
    ASSERT(!response.isNull()); 
    ASSERT(m_state == Initialized); 
    // Reference the object in this method since the additional processing can do 
    // anything including removing the last reference to this object; one example of this is 3266216. 
    Ref<SubresourceLoader> protect(*this); 
    if (m_resource->resourceToRevalidate()) { **** 
     if (response.httpStatusCode() == 304) { 
      // 304 Not modified/Use local copy 
      // Existing resource is ok, just use it updating the expiration time. 
      m_resource->setResponse(response); 
      memoryCache()->revalidationSucceeded(m_resource, response); 
      if (!reachedTerminalState()) 
       ResourceLoader::didReceiveResponse(response); 
      return; 
     } 
     // Did not get 304 response, continue as a regular resource load. 
     memoryCache()->revalidationFailed(m_resource); 
    }

Czy wiesz, jakie działania prowadzą do tego? Na przykład jaki adres URL otwierasz w UIWebView lub może jest to załadowana strona i próbujesz kliknąć łącze i tę stronę? Sądzę też, że UIWebView używa tego samego kodu co Safari i znajduje się tutaj https://trac.webkit.org/browser. –

+0

Dzieje się to podczas uruchamiania mojej aplikacji. Nie mogę udostępnić adresu URL, ponieważ znajduje się on w prywatnym zakresie adresów IP. Myślę, że ma to coś wspólnego z pamięcią podręczną aplikacji HTML5, ponieważ moja strona korzysta z tego –

. Wystarczy otworzyć prywatny URL w UIWebView i uzyskać awarię, prawda? I zdarza się to często (więc jest odtwarzalne) z tym samym miejscem awarii? –

Jeśli to działało po reinstalacji następnie można spróbować zrobić żądania URL bez buforowania, gdyż zakładam, że dadzą ten sam wynik:

NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:30]; 
[webView loadRequest:request];

Zgaduję, coś jest nie tak z buforowanie zasobu.

Jeśli dostanę szansę, wypróbuję kilka rzeczy na podstawie tego i niektórych innych pomysłów w komentarzach. Dzieki za sugestie –
