iOS 根据状态栏判断网络状态

通过顶部状态栏获取当前的网络状态

定义网络状态枚举

    typedef enum : NSUInteger {
        NetworkStatusUnkown,
        NetworkStatus2G,
        NetworkStatus3G,
        NetworkStatus4G,
        NetWorkStatusWiFi,
    } Networkstatus;

获取状态栏上的网络图标

获取当前的网络状态码

      NSUInteger networkCode = [[vv valueForKeyPath:@"dataNetworkCode"] integerValue];
            Networkstatus netState = NetworkStatusUnkown;
            switch (networkCode) {
                case 0:
                    netState = NetworkStatusUnkown;
                    break;
                case 1:
                    netState = NetworkStatus2G;
                    break;
                case 2:
                    netState = NetworkStatus3G;
                    break;
                case 3:
                    netState = NetworkStatus4G;
                    break;
                case 4:
                    netState = NetWorkStatusWiFi;
                    break;
                    
                default:
                    break;
            }
