iPhone Data Usage Tracking/Monitoring

Question

I\'ve searched over this topic but found very few details which were helpful. With these details I\'ve tried to cook some code as follows.

Note: Please compa

Answer 1

The thing is that pdp_ip0 is one of interfaces, all pdpXXX are WWAN interfaces dedicated to different functions, voicemail, general networking interface.

I read in Apple forum that : The OS does not keep network statistics on a process-by-process basis. As such, there's no exact solution to this problem. You can, however, get network statistics for each network interface.

In general en0 is your Wi-Fi interface and pdp_ip0 is your WWAN interface.

There is no good way to get information wifi/cellular network data since, particular date-time!

Data statistic (ifa_data->ifi_obytes and ifa_data->ifi_ibytes) are stored from previous device reboot.

I don't know why, but ifi_opackets and ifi_ipackets are shown just for lo0 (I think its main interface ).

Yes. Then device is connected via WiFi and doesn't use internet if_iobytes values still come because this method provides network bytes exchanges and not just internet.

Improved copy/paste support !
