How do I get current network location name?

In system network preference there are some loca开发者_运维百科tion names.How to get the current or active network location name and list of all network locations?

I guess SystemConfiguration.framework supports this but i didn't get exactly which API to use.

Thanks in advance for your answer.

You can use SCPreferencesCreate to get the preferences, then SCNetworkSetCopyAll to get just the network locations. SCNetworkSetGetName will get the name of a location.

SCPreferencesRef prefs = SCPreferencesCreate(NULL, @"SystemConfiguration", NULL);
NSArray *locations = (NSArray *)SCNetworkSetCopyAll(prefs);
for (id item in locations) {
    NSString *name = (NSString *)SCNetworkSetGetName((SCNetworkSetRef)item);
    ...
}
CFRelease(locations);
CFRelease(prefs);

Read "System Configuration Programming Guidelines" for more.

This is a swift 5.1 implementation to get list of all available network location

    func getAvailabeNetworkLocation() -> [String]
{
    var results = [String]()

    
    var prefs : SCPreferences
    prefs = SCPreferencesCreate (nil, "Softech" as CFString, nil)!
    var sets : CFArray
    sets = SCNetworkSetCopyAll (prefs)!
    
    let count = CFArrayGetCount(sets) as Int
    var newSet : SCNetworkSet? = nil
    var bFound : Bool = false
    
   

    
    for nIndex  in 0..<count {
     let mySet = CFArrayGetValueAtIndex (sets, nIndex)
     let key = Unmanaged<SCNetworkSet>.fromOpaque(mySet!)
        newSet = key.takeUnretainedValue()
        let name : String = SCNetworkSetGetName(newSet!)! as String
        print("Network location name: \(name)")
     results.append(name)
    }
    return results
}
