iphone – 如何使用iOS中的图像缓存整个网页

在我上面喜欢的页面上,有一些很好的例子,如何使用它,但我会包括其中一个在这里完整性：

- (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
{
   NSString *response = [NSString StringWithContentsOfFile:
      [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 loadHTMLString:response baseURL:[request url]];
}
