objective-c - iOS有关于流量统计的问题，求大神～

Question

项目是一个类似交友社区的应用，然后老大想知道用户在观看视频花了多少流量，我在网上找了很久，都没有这种类似某个时间段的流量统计，苹果官方文档我也不知道该从哪入手，望有知道的大神们指点一下！

Answer 1

A more precise method: Expand the player yourself (such as ijkplayer) to get the received and sent traffic data.
To be crude, it is to monitor network card traffic, which cannot distinguish applications.

Answer 2

Look at the NSURLProtocol class which should help.
