推荐答案

来自问题我得到了这个答案，尽管它是关于下载速度的，但是您也可以从中计算出上传速度.测量上传的字节差和调用代理之间的时间差，然后可以计算正在进行的速度，以每秒字节数(或其他时间单位)为单位.

From a question I got this answer though it was for download speed but You can also calculate upload speed form this. Measure the difference in bytes uploaded and the difference in time between calls to the delegate, then you can calculate the ongoing speed in bytes per second (or other time unit).
