在OS X上获取活动网络连接

Question

有没有任何方法可以在不使用shell脚本的情况下检索活动/非活动网络连接？ CWInterface只给出了WiFi网络状态信息和CNCopyCurrentNetworkInfo不可用在OS X

Answer 1

 CWInterface* wifi = [[CWWiFiClient sharedWiFiClient] interface]; 
     int secType  = (int)[wifi security]; 
     int channel  = (int) [[wifi wlanChannel] channelNumber]; 
     int rssi  = [wifi rssiValue]; 
     NSString *ssid = [wifi ssid]; 
     NSString *bssid = [wifi bssid];
