data plan monitoring

Hey all,

Does xcode have a way to determine your data plan usage. If not is there a way to record what you are downloading from the internet?

Thanks

It's not up to Xcode. And no.

But there are apps that keep track of your data usage. How do they do it?

maybe they take infos from a webpage offered by the carrier

I thought they might contact the provider but then they would have to contact every provider and know which on you are using.

I downloaded a free one to try it out. I am just using the wi-fi part of it because I only have an iPod. And just having the wi-fi on make the data usage go up. And when I go on youtube the data usage goes way up. Im just using local wi-fi. Could the app just be counting up as long as I have my wi-fi turned on and it doesn't actually know my data usage?

There's always a chance I might be wrong, but what dany said sounds more plausible. Can you post a link to a few of those apps.

DataMan Free: DataMan Free - Real Time Data Usage Manager for iPhone, iPod touch, and iPad on the iTunes App Store

Data Control App: Data Control App for iPhone, iPod touch, and iPad on the iTunes App Store

According to the reviews for dataman, its doesnt give accurate values.

But some of the other apps are said to be quite accurate.

mmm.....this is what i found on dev forum apple.

Quote:

You can get per-interface statistics via a reasonably well-supported technique, namely, call get <x-man-page://3/getifaddrs> get the list of addresses on the system and then, for each AF_LINK address, cast the ifa_data field to a (const struct if_data *) and access the interface statistics from there.

There are two gotchas here:

o There's no good way to identity an interface as being the cellular data interface (or the Wi-Fi for that matter). You can hard-code BSD interface names (for example, "en0"), but that's not a great long-term plan.

o These statistics are all reset to zero on startup. While iPhone OS might track statistics across restarts, there's no public API to get that information.

Ya I saw that too and I was really hoping there was another way.

dany_dev · 06-24-2011, 11:16 AM

i'm pretty sure that there aren't other ways...with public api

Shades of Chaos · 06-24-2011, 01:54 PM

Im restricted to public api's.
Thanks for all the help guys.
