comment mettre en cache une page Web entière avec des images dans iOS

Le projet ASIHTTPRequest a une class appelée ASIWebPageRequest qui est conçue pour faire exactement ce que vous voulez. Si vous êtes d'accord pour append une dépendance supplémentaire à votre projet, je pense que c'est une bonne solution pour vous: ASIWebPageRequest .

Sur la page que j'ai aimée ci-dessus, il y a quelques bons exemples de comment l'utiliser, mais je vais inclure l'un d'eux ici pour l'exhaustivité:

 - (IBAction)loadURL:(NSURL *)url { // Assume request is a property of our controller // First, we'll cancel any in-progress page load [[self request] setDelegate:nil]; [[self request] cancel]; [self setRequest:[ASIWebPageRequest requestWithURL:url]]; [[self request] setDelegate:self]; [[self request] setDidFailSelector:@selector(webPageFetchFailed:)]; [[self request] setDidFinishSelector:@selector(webPageFetchSucceeded:)]; // Tell the request to embed external resources directly in the page [[self request] setUrlReplacementMode:ASIReplaceExternalResourcesWithData]; // It is strongly recommended you use a download cache with ASIWebPageRequest // When using a cache, external resources are automatically stored in the cache // and can be pulled from the cache on subsequent page loads [[self request] setDownloadCache:[ASIDownloadCache sharedCache]]; // Ask the download cache for a place to store the cached data // This is the most efficient way for an ASIWebPageRequest to store a web page [[self request] setDownloadDestinationPath: [[ASIDownloadCache sharedCache] pathToStoreCachedResponseDataForRequest:[self request]]]; [[self request] startAsynchronous]; } - (void)webPageFetchFailed:(ASIHTTPRequest *)theRequest { // Obviously you should handle the error properly... NSLog(@"%@",[theRequest error]); } - (void)webPageFetchSucceeded:(ASIHTTPRequest *)theRequest { NSSsortingng *response = [NSSsortingng ssortingngWithContentsOfFile: [theRequest downloadDestinationPath] encoding:[theRequest responseEncoding] error:nil]; // Note we're setting the baseURL to the url of the page we downloaded. This is important! [webView loadHTMLSsortingng:response baseURL:[request url]]; }
