我想使用UIWebView來加載一個HTML網址,但不要在HTML中加載圖像。我想要UIWebView只是在html中顯示純文本。由於某種原因,我無法在加載前更改html內容。如何停止在UIWebView中加載圖像?

有沒有什麼方法可以達到這個目的?

也許你可以使用這個http://stackoverflow.com/questions/2067943/iphone-SDK-告訴-的UIWebView而不是到負載的圖像,和CSS-剛剛純HTML和JS的。 – simonbs 2012-03-20 08:54:21

- (NSCachedURLResponse*)cachedResponseForRequest:(NSURLRequest*)request 
{ 
    NSURL *url = [request URL]; 
    BOOL blockURL = [[FilterMgr sharedFilterMgr] shouldBlockURL:url]; 
    if (blockURL) { 
     NSURLResponse *response = 
       [[NSURLResponse alloc] initWithURL:url 
             MIMEType:@"text/plain" 
          expectedContentLength:1 
           textEncodingName:nil]; 

     NSCachedURLResponse *cachedResponse = 
       [[NSCachedURLResponse alloc] initWithResponse:response 
          data:[NSData dataWithBytes:" " length:1]]; 

     [super storeCachedResponse:cachedResponse forRequest:request]; 

     [cachedResponse release]; 
     [response release]; 
    } 
    return [super cachedResponseForRequest:request]; 
}

有些方法可以在源代碼中加載圖像,而不需要靜態img標籤,包括通過JavaScript和CSS。 – titaniumdecoy 2012-04-19 22:52:48
