Question

我使用以下代码从webview中的服务器加载网页： -

-(void)loadView
{
    [super loadView];

[[self request] setDelegate:nil];    
    [[self request] cancel];    
    [self setRequest:[ASIWebPageRequest requestWithURL:navigationURL]];    
    [[self request] setDelegate:self];   
    [[self request] setDidFailSelector:@selector(webPageFetchFailed:)];   
    [[self request] setDidFinishSelector:@selector(webPageFetchSucceeded:)];
    [[self request] setShouldPresentProxyAuthenticationDialog:YES];
    [[self request] setShouldPresentCredentialsBeforeChallenge:YES];
    [[self request] setShouldPresentAuthenticationDialog:YES];

    // 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];

}

从用户输入网址的屏幕中选取导航网址。

在此之后

- (void)webPageFetchSucceeded:(ASIHTTPRequest *)theRequest 
{    NSString *response = [NSString stringWithContentsOfFile:       
      [theRequest downloadDestinationPath] encoding:[theRequest responseEncoding] error:nil];    

NSString *html = [NSString stringWithContentsOfFile:[theRequest downloadDestinationPath]  encoding:NSUTF8StringEncoding    error:nil];     

  NSData*  data = [html dataUsingEncoding:NSUTF8StringEncoding]; 

[web loadData:data MIMEType:@"text/html" textEncodingName:@"utf-8" baseURL:navigationURL];

}

尝试了不同的MIME类型，但没有成功。链接在iPad的野生动物园中打开非常精细并且显示al d图像但是当我进入webview时它不显示图像的相同链接.. 如何克服这个......无法找到解决方案:(
