查询WiFi和蜂窝数据连接时如何获取实时信息

Question

在查看此post后，我编写了以下例程，以编程方式确定蜂窝和WiFi数据的连接状态。

我编写的例程效果很好，但与设备屏幕顶部的WiFi和蜂窝连接图标显示的状态相比，它返回​​的信息延迟了大约20到40秒。

以下是代码：

- (PSTR) isLinkedToTypeCom: (PSTR) reqTypCom andTypeFam: (int) reqTypFam
    //...reqTypCom = "pdp_ip0" or "en0"    aka (cell or WiFi)
    //   reqTypFam = AF_INET or AF_INET6   aka ("IPv4" or IPv6")
    //
    //...derived from from Stack Overflow:
    //   https://stackoverflow.com/questions/31721696/ios-check-if-cellular-technology-available-even-if-the-device-is-on-wifi
    //...returns an ip address string if both the reqTypCom and the reqTypFam are
    //   matched and the entry is active.  otherwise, it will return NULLSTR.
       {
       struct ifaddrs * pAddrs;
       struct ifaddrs * pAddr;
       NSString         ipAdr = NULLSTR;

       if ( getifaddrs( &pAddrs ) == 0 )
          {
          pAddr = pAddrs;

          while( pAddr != NULL )
             {
             NSString * curTypCom = [NSString stringWithUTF8String: pAddr->ifa_name ];

             if ( [curTypCom isEqualToString: reqTypCom] )
                {
                sa_family_t curTypFam = pAddr->ifa_addr->sa_family;
                bool         isActive = pAddr->ifa_flags & IFF_UP;

                if ( curTypFam == reqTypFam && isActive == true )
                   {
                   if ( reqTypFam == AF_INET )
                      {
                      ipAdr = [NSString stringWithUTF8String:
                               inet_ntoa(((struct sockaddr_in *)pAddr->ifa_addr)->sin_addr)];
                      break;
                      }

                   if ( reqTypFam == AF_INET6 )
                      {
                      char tmp[INET6_ADDRSTRLEN];

                      inet_ntop(AF_INET6, &(((struct sockaddr_in6 *)pAddr->ifa_addr)->sin6_addr), tmp, INET6_ADDRSTRLEN);
                      ipAdr = [NSString stringWithUTF8String: tmp];
                      break;;
                      }
                   }
                }
             pAddr = pAddr->ifa_next;
             }
          freeifaddrs(pAddrs);
          }

       return( ipAdr );
       }

我的问题：我是否可以通过编程方式获取所需信息，而无需等待20到40秒？
