解决iOS13 无法获取WiFi名称（SSID）问题

NSString* phoneVersion = [[UIDevice currentDevice] systemVersion];  CGFloat version = [phoneVersion floatValue];  // 如果是iOS13 未开启地理位置权限 需要提示一下  if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined && version >= 13) {    self.locationManager = [[CLLocationManager alloc] init];    [self.locationManager requestWhenInUseAuthorization];  }

#import <SystemConfiguration/CaptiveNetwork.h>

- (NSString *)currentWifiSSID{  NSString *ssid = nil;  NSArray *ifs = (__bridge  id)CNCopySupportedInterfaces();  for (NSString *ifname in ifs) {    NSDictionary *info = (__bridge id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifname);    if (info[@"SSIDD"])    {      ssid = info[@"SSID"];    }  }  return ssid;}
