Can the iPhone SDK obtain the Wi-Fi SSID currently connected to?

Question

In the iPhone SDK I don\'t see the same SCDynamicStore used on Mac OS X to get the SSID name that your wireless network is currently connected to isn\'t availab

Answer 1

After digging around I found the anser to this. There are unpublished APIs in the Preferences framework. For examples of this one can look at the Stumbler code hosted on Google Code.

I filed a radar with Apple (#6407431/OpenRadar version) that was marked as a duplicate of #5814810). If you want this officially supported then please also file a radar at bugreport.apple.com.

Update: The above Stumbler code is for 1.x revision iPhone OS SDK. For iPhone OS 2.0 and beyond developers will have to look in PrivateFrameworks/Apple80211.Framework and all that implies.

Answer 2

This is now possible (iOS 4.1+) via the Captive Network API.

See an example of how to use it on this similar question.

This is not a private API.

Answer 3

Try this code,

#import <SystemConfiguration/CaptiveNetwork.h>

CFArrayRef myArray = CNCopySupportedInterfaces();
CFDictionaryRef myDict = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));
NSDictionary *ssidList = (__bridge NSDictionary*)myDict;
NSString *SSID = [ssidList valueForKey:@"SSID"];
