NSArray *ifs = (__bridge_transfer id)CNCopySupportedInterfaces();
 
    NSLog(@"Supported interfaces: %@", ifs);
 
    id info = nil;
 
    for (NSString *ifnam in ifs) {
 
        info = (__bridge_transfer id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);
 
        NSLog(@"%@ => %@", ifnam, info);  //单个数据info[@"SSID"]; info[@"BSSID"];
 
        if (info && [info count]) { break; }
