推荐答案
ASIHTTPRequest 项目有一个名为 ASIWebPageRequest
的类旨在完全满足您的需求.如果您可以为项目添加额外的依赖项,那么我认为这对您来说是一个很好的解决方案:ASIWebPageRequest.
The ASIHTTPRequest project has a class called ASIWebPageRequest
which is designed to do exactly what you want. If you're okay with adding an additional dependency to your project then I think it's a good solution for you: ASIWebPageRequest.
在上面我喜欢的页面上有一些很好的示例说明如何使用它,但为了完整起见,我将在此处包含其中一个示例:
On the page I liked above there are some good examples of how to use it but I'll include one of them here for completeness:
- (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]];
}
