ios - ASIHttpRequest请求:didReceiveBytes: not working as expected

Question

我确信对此有一个非常简单的解释，但我对此事感到抓狂。

    -(void)addRequestWithUrl:(NSURL *)url savePath:(NSString *)path
    {
      ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
      request.userInfo = [[NSMutableDictionary alloc] initWithObjectsAndKeys:path, @"savePath", nil];
      networkQueue.showAccurateProgress = YES;
      [self.networkQueue addOperation:request];
      [self.networkQueue setDownloadProgressDelegate:self];
    }

    -(void)request:(ASIHTTPRequest *)request didReceiveBytes:(long long)bytes
    {
       DLog(@"bytes: %llu", bytes);
    }

didReceiveBytes 从未被调用过。如果我将下载进度委托(delegate)设置为每个请求而不是队列，则会调用 didReceiveBytes 方法，但仅在每个请求完全完成后调用，并且值始终为 1。

有什么建议吗？这里出了什么问题？ (顺便说一句，在 iOS 上工作)

这可能有帮助:

[request setDidReceiveDataSelector:@selector(request:didReceiveBytes:)];
