在iPhone上以编程方式测量网络流量

Question

I'm interested in measuring the network traffic for my application. Ideally I would need to separate wireless from 3G network traffic. I can't seem to find any API that gets this information; however I see that there is at least one app in the AppStore that does something close (they actually sum up the traffic for the entire phone).

Any ideas?

Answer 1

I've found one approximate solution: getifaddrs can be used to get statistics on network usage.

One advantage is that it can get separate statistics for Wi-Fi and WWAN interfaces.

A disadvantage is that on multi-tasking devices those interfaces may be used by multiple applications and the statistics are cumulated.

I also was looking for solution and found it here: iPhone Data Usage Tracking/Monitoring
