CLGeocoder Error Domain=kCLErrorDomain Code=2

使用CLGeocoder解码地址时，遇到错误 Error Domain=kCLErrorDomain Code=2

代码：

#pragma mark 跟踪定位代理方法，每次位置发生变化即会执行（只要定位到相应位置）
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
    CLLocation *location=[locations firstObject];//取出第一个位置
    CLLocationCoordinate2D coordinate=location.coordinate;//位置坐标
    NSLog(@"经度：%f,纬度：%f,海拔：%f,航向：%f,行走速度：%f",coordinate.longitude,coordinate.latitude,location.altitude,location.course,location.speed);
    
    CLGeocoder *gcode = [[CLGeocoder alloc]init];
    [gcode reverseGeocodeLocation:location completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {
        if (error) {
            NSLog(@"%@",error);
        }else
        {
            CLPlacemark *mk = [placemarks objectAtIndex:0];
            NSString *state = [mk.addressDictionary objectForKey:@"State"];
            NSString *city = [mk.addressDictionary objectForKey:@"City"];
            NSString *lity = [mk.addressDictionary objectForKey:@"SubLocality"];
            NSString *stret = [mk.addressDictionary objectForKey:@"Street"];
            NSString *name = [mk.addressDictionary objectForKey:@"Name"];
        
        }
        isGettingLocation = NO;
    }];
    
    //如果不需要实时定位，使用完即使关闭定位服务
    [_locationManager stopUpdatingLocation];
}

错误原因：

   地址解析需要网络，检查网络连接！手机是否断网了
