ios 13 适配问题

1、获取Wi-Fi ssid

+ (NSString *)getWiFiSSID {

if (@available(iOS 13.0, *)) {

        //用户明确拒绝，可以弹窗提示用户到设置中手动打开权限

        if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied) {

            //使用下面接口可以打开当前应用的设置页面

            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

        }

        

        self.clLocationManager = [[CLLocationManager alloc] init];

        self.clLocationManager.delegate = self;

        if(![CLLocationManager locationServicesEnabled] || [CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined){

            //弹框提示用户是否开启位置权限

            [self.clLocationManager requestWhenInUseAuthorization];

        }

    }

 

 

   NSArray *ifs = (__bridge id)CNCopySupportedInterfaces();

   id info = nil;

   for (NSString *ifnam in ifs)

   {

       info = (__bridge id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);

       if (info && [info count])

       {

           break;

       }

   }

   NSDictionary *dctySSID = (NSDictionary *)info;

   NSString *ssid = [[dctySSID objectForKey:@"SSID"] lowercaseString];

   return ssid;

}

如果打开定位之后还是不能获取到ssid，请前往开发者中心，确认是否配置了Wi-Fi权限。
