iphone - 如何使用 asihttprequest 跟踪单个下载速度

Question

有人可以帮我解决 asihttprequest 吗？

我想跟踪我下载的每个文件的下载速度，而不是所有文件的平均速度。

对于所有下载的平均速度，有[ASIHTTPRequest averageBandwidthUsedPerSecond] 但是我可以使用什么来跟踪每次下载？

谢谢

考虑到 ASI 已死，我最近不得不在一个较旧的项目上执行此操作。如果其他人需要帮助:

-(void)request:(ASIHTTPRequest *)request didReceiveBytes:(long long)bytes
{
    if (!lastBytesReceived)
        lastBytesReceived = [NSDate date];

    NSTimeInterval interval = [[NSDate date] timeIntervalSinceDate:lastBytesReceived];

    float KB = (bytes / 1024);

    float kbPerSec =  KB * (1.0/interval); //KB * (1 second / interval (less than one second))

    NSLog(@"%llu bytes received in %f seconds @ %0.01fKB/s",bytes,interval, kbPerSec);

    lastBytesReceived = [NSDate date];
}
