保存HTML页面的图像，在iPhone应用程序中的一个文件夹中的JavaScript和CSS

我想保存网页在图像，CSS和JavaScript等文件目录。

我做了下面的代码：但它只生成HTML文件..

NSURL *url = [NSURL URLWithString:@"http://www.apple.com"]; NSData *urlData = [NSData dataWithContentsOfURL:url]; [urlData writeToFile:filePath atomically:YES]; 

任何想法或build议是最受欢迎的。

谢谢

ASIHTTPRequest项目有一个名为ASIWebPageRequest的类，它被devise成完全按照你想要的来做。 如果您可以为您的项目添加额外的依赖项，那么我认为这是一个很好的解决scheme： ASIWebPageRequest 。

在上面我喜欢的页面中，有一些如何使用它的很好的例子，但是为了完整性，我将其中的一个包含在这里：

 - (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]]; }
