你好，有个问题遇到了，在使用这个做webview的缓存的时候，特别问下哈

start loading 里面的这个，就是走了缓存了
if (data) { NSURLResponse *response = [[NSURLResponse alloc] initWithURL:mutableReqeust.URL MIMEType:[NSData sd_contentTypeForImageData:data] expectedContentLength:data.length textEncodingName:nil]; [self.client URLProtocol:self didReceiveResponse:response cacheStoragePolicy:NSURLCacheStorageNotAllowed]; [self.client URLProtocol:self didLoadData:data]; [self.client URLProtocolDidFinishLoading:self]; } else { self.connection = [NSURLConnection connectionWithRequest:mutableReqeust delegate:self]; }

完了，如果我后台去请求下载这个URL，完了，更新缓存，完了 怎么样 更新 当前页面呢？ 因为当前页面用的是 一进来从缓存拿到的数，后来我又在后台更新了缓存，有可能 缓存不一样了，所以我要顺便也更新下 当前页面，如果调用
[self.client URLProtocol:self didReceiveResponse
[self.client URLProtocol:self didLoadData
[self.client URLProtocolDidFinishLoading
这三个代理方法，我看了是不管用的，也就是说webview当前页面，并没有二次更新下页面(最最新的缓存)

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { self.responseData = [[NSMutableData alloc] init]; [self.client URLProtocol:self didReceiveResponse:response cacheStoragePolicy:NSURLCacheStorageNotAllowed]; } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [self.responseData appendData:data]; [self.client URLProtocol:self didLoadData:data]; } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { UIImage *cacheImage = [UIImage sd_imageWithData:self.responseData]; //利用SDWebImage提供的缓存进行保存图片 [[SDImageCache sharedImageCache] storeImage:cacheImage recalculateFromImage:NO imageData:self.responseData forKey:[[SDWebImageManager sharedManager] cacheKeyForURL:self.request.URL] toDisk:YES]; [self.client URLProtocolDidFinishLoading:self]; }

iOS中的 NSURLProtocol

最近做SDK开发的时候，为了给QA编写一个测试工具，方便调试和记录请求内容。但是又不想改动已经写好的SDK代码。本来想到用methodSwizzle，但是发现SDK要开放一些...
