Question

我想从下载中显示进度。我想加载一个Document并在Webview中显示它。

一切正常，只有我的进度（ - （void）setProgress：（float）newProgress方法）显示4次并且显示值：0.000000。

甚至 - （void）请求：（ASIHTTPRequest *）请求didReceiveBytes :( long long）bytes方法从接收到的字节1跳转到其原始大小。

我做错了什么？

服务器向我发送响应标头：

    "Cache-Control" = "private,max-age=0";
    "Content-Length" = 22993;
    "Content-Type" = "application/vnd.ms-word.document.12";

    "X-Content-Type-Options" = nosniff;
    "X-Powered-By" = "ASP.NET";
    "X-SharePointHealthScore" = 0;
}

ASIHTTPRequest *asiRequestTemp = [ASIHTTPRequest requestWithURL:[NSURL URLWithString: self.documentURL]];
[asiRequestTemp setTimeOutSeconds:10];


[self setAsiRequestDocumentViewer:asiRequestTemp];

[asiRequestDocumentViewer setDelegate:self];


[asiRequestDocumentViewer setUseKeychainPersistence:YES];
[asiRequestDocumentViewer setUseSessionPersistence:YES];


 [asiRequestDocumentViewer setShowAccurateProgress:YES];
    [asiRequestDocumentViewer setDownloadProgressDelegate:self];

    [asiRequestDocumentViewer setDownloadDestinationPath:mediaPath];
    [asiRequestDocumentViewer startAsynchronous];

这有什么不对，甚至显示内容长度！

我遇到了类似的问题。您下载的数据有多大？你有没看过它是怎么进来的？ ASIHTTPRequest在成功下载标题之前不会开始更新进度下载，并且我注意到如果数据足够小以进行两次或三次突发，则只会调用值为0.0和1.0的setProgress

使用ASIHTTPRequest，也是AccurateProgress，进度从0跳到1
