iOS development monitors mobile phone traffic usage

There are several problems in getting mobile phone usage traffic:
①ios is unable to monitor the boot and shutdown broadcasts like Android, immediately shuts down and then turns on, and the traffic on the monitored mobile network is emptied by default.
② application in the background running, suddenly killed, unable to traffic statistics, need to be in the background when the application to save the flow of usage
③ If the user first opens the flow statistics software in February, when the 3rd month is opened, the traffic should be zero for February. But the problem is, what we can get is the total amount of traffic that is consumed from the start of the monitoring. Package flow for 1000M per month, if the February consumption of 200M traffic, March consumption of 300M traffic, we can not determine the March flow of surplus, we obtained the use of traffic for 500M. It is recommended that when the new one month begins, the user opens the app for the first time, reminding the user to reset the remaining traffic.
