ios13 CNCopyCurrentNetworkInfo 不管用

根据wwdc的要求CNCopyCurrentNetworkInfo这个接口符合以下三个条件才能获取当前的Wi-Fi名字：

• Apps with permission to access location   
• Your app is the currently enabled VPN app   
• Your app configured the WiFi network the device is currently using via NEHotspotConfiguration

最简单的是获取用户的地理位置权限；

 

 CLLocationManager*   _myLocationManager = [[CLLocationManager alloc] init];
 _myLocationManager.delegate = self;
_myLocationManager.desiredAccuracy = kCLLocationAccuracyBest;//精确度
_myLocationManager.distanceFilter =1000.0f;//= 5;这个表示在地图上每隔1000m才更新一次定位信息。
 [_myLocationManager requestWhenInUseAuthorization];//?只在前台开启定位

或者[_myLocationManager requestAlwaysAuthorization];
