iOS 获取连接的wifi的ssid的方法是不是不能用了？

现在获取连接wifi的ssid的方法是不是不能用了？

(NSString *)getCurrentWifiSSID { NSString *ssid = nil; NSArray *ifs = (__bridge_transfer id)CNCopySupportedInterfaces(); for (NSString *ifnam in ifs) { NSDictionary *info = (__bridge_transfer id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam); NSLog(@"%@", info); if (info[@"SSID"]) { ssid = info[@"SSID"]; } } return ssid; }
