On the iPhone, is it possible to find out which WIFI network we are connected to?

Question

If yes, can we also get additional information about the network configuration?

One useful way to do this could be getting the SSID of the current network. Is there an API to do that?

Update: I found a similar question here:

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

Solution 1

(Separate answer to preserve history etc.)

It looks like you might not be able to determine the SSID of the WLAN to which you're connected, at least in an app that will go into the App Store. These people use a private API - Preferences.framework - to get to the details of the WLAN (like "is it hidden?" "What's the name?" etc.).

Solution 2

Try following method:

#import <SystemConfiguration/CaptiveNetwork.h>

NSString *wifiName = @"Not Found";
CFArrayRef myArray = CNCopySupportedInterfaces();

if (myArray != nil) {

    CFDictionaryRef myDict = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));

    if (myDict != nil) {
        NSDictionary *dict = (NSDictionary*)CFBridgingRelease(myDict);

        wifiName = [dict valueForKey:@"SSID"];

    }  
}

NSLog(@"wifiName:%@", wifiName);

Can't comment, but this might be a duplicate:

Answer seems to be no. I've done my own research on this and have been unable to find a supported way of getting the SSID.
