Ben yığın izleme içine biraz daha fazla araştırma yaptım ve burada Subresourceloader için kod bulundu (https://webkit.googlesource.com/WebKit/+/master/Source/WebCore/loader/SubresourceLoader.cpp). Üstelik daha önbelleğe olmadan URL isteği yapıyor deneyebilirsiniz bir yeniden yükleme sonrasında çalıştıysa

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); 
    }

Bunun için hangi işlemlerin yapıldığını biliyor musunuz? Örneğin, UIWebView'da açmaya çalıştığınız URL ya da yüklenmiş sayfa var ve bağlantıya ve bu sayfaya dokunmaya çalışın mı? Ayrıca UIWebView, Safari ile aynı kodu kullanır ve burada https://trac.webkit.org/browser adresinde bulunur. –

Uygulamamı başlatırken oluyor. URL'yi özel bir IP aralığında olduğundan paylaşamıyorum. Sitemin –

kullanıyor olması nedeniyle HTML5 uygulama önbelleği ile ilgili bir şey olduğunu düşünüyorum. Bu yüzden UIWebView'da özel URL'nizi açıp bu çökmeyi alıyorsunuz, değil mi? Ve bu sık sık (yani tekrarlanabilir) aynı çarpışma yeri ile olur mu? –

:

Benim tahminim m_resource çökmesine neden ile işaretlenmiş Bu noktada (****) en BOŞ olmasıdır Ben bir şey bir kaynağın önbelleğe yanlış gidiyor tahmin ediyorum

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

: ben varsayılabilir çünkü aynı sonucu verecektir.
