objective c - listout all wi-fi SSID programatically in iphone -


1). want list of wi-fi ssid programatically in iphone.

i try following code give connected ssid detail.

nsarray *ifs = (id)cncopysupportedinterfaces(); nslog(@"%s: supported interfaces: %@", __func__, ifs); id info = nil; (nsstring *ifnam in ifs) {     info = (id)cncopycurrentnetworkinfo((cfstringref)ifnam);     nslog(@"%s: %@ => %@", __func__, ifnam, info);     if (info && [info count]) {         break;     }     [info release]; }

2). question how can identify if come range in wi-fi when wi-fi off. possible identify in range of wi-fi when wi-fi off ?

1) can details current network, such ssid or bssid, using captivenetwork framework you're using in example. apple doesn't allow developers seek other networks in addition 1 user connected.

2) according reachability page, can use library check if user connected via 3g or wifi. can't know if in range when wi-fi set off.
