ios - Get current type of internet connection -

i want technology of radio access (internet connection), observe if device connected wifi or wwan connection (and in case, type of wwan : gprs, egde, 3g, 3g+, 3g++, or 4g).

does cttelephonynetworkinfo works iphone , ipad on ios7.1 ?

i've tried observe wifi connection on ipad print null result. code :

cttelephonynetworkinfo *telephonyinfo = [cttelephonynetworkinfo new]; nslog(@"current radio access technology: %@", telephonyinfo.currentradioaccesstechnology);

someone can told me why ? i'm not sure understand this...

thanks help

that's because currentradioaccesstechnology homecoming radio access technology (not whether it's wifi or wwan). illustration of homecoming value ctradioaccesstechnologylte.

to informed whether app connect wifi or wwan, should utilize reachability.

there several implementations available.

ios objective-c
