ASIHTTPRequest的setDownloadProgressDelegate不起作用

Question

我想从服务器下载大尺寸的zip文件，为此我正在使用ASIHTTPRequest.I已成功下载文件但我想显示进度条。我已经实现了它就像ASIHTTPRequest的例子但我的进度条是没有显示进展。我的代码在

之下

  [networkQueue reset];
  networkQueue setRequestDidFinishSelector:@selector(imageFetchComplete:)];
[networkQueue setRequestDidFailSelector:@selector(imageFetchFailed:)];
    [networkQueue setDelegate:self];
    request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:fullURL]];
    fullPathTemp = [NSString stringWithFormat:@"%@/temp.zip", self.documentsDir];
    [request setDownloadProgressDelegate:progressIndicator];
    [request setDownloadDestinationPath:fullPathTemp];
    [request setUserInfo:[NSDictionary dictionaryWithObject:@"request1" forKey:@"name"]];
    [request setShouldContinueWhenAppEntersBackground:YES];
    [networkQueue addOperation:request];
   [networkQueue go];

先谢谢。
