iPhone netword SSID

Question

I am having issues implementing the code from the answer on this question: iPhone get SSID without private library

I have xcode 4.2 and iOS 5.1.

 #import <SystemConfiguration/CaptiveNetwork.h>

- (id)fetchSSIDInfo
{
    NSArray *ifs = (id)CNCopySupportedInterfaces();
    NSLog(@"%s: Supported interfaces: %@", __func__, ifs);
    id info = nil;
    for (NSString *ifnam in ifs) {
        info = (id)CNCopyCurrentNetworkInfo((CFStringRef)ifnam);
        NSLog(@"%s: %@ => %@", __func__, ifnam, info);
        if (info && [info count]) {
            break;
        }
        [info release];
    }
    [ifs release];
    return [info autorelease];
}

I get the following errors:

What am I doing wrong?

You need to add CFNetwork.framework to your project.

You can do it by selecting Targets > Summary> Linked Framework and Libraries.

I added it but I still have the 3 errors. Am I missing something else? – MrHappyAsthma Jul 18 '12 at 23:40
try cleaning the project, re-build it, quit xcode and start again. sometimes it helps :) – Maggie Jul 18 '12 at 23:41
It requires the SystemConfiguration framework also. Then it worked :D – MrHappyAsthma Jul 18 '12 at 23:43
