iOS, GMSMapView, MapView: сбой приложения didTapMarker

Question

мое приложение падает, когда пользователь нажимает на маркер (GMSMapVIew: didTapMarker), и myApp работает хорошо в 99% случаев, но иногда он показывает сбой при сбое. И это произошло так случайно.

Отчет о сбое показывает следующее.

Crashed: com.apple.main-thread
EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x00000002f6ce97f4

-[BadgerMapView mapView:didTapMarker:]

Ниже мой код, где приложение сбой .

BadgerMapView.m: 1784

if (! [Waypt isKindOfClass: [NSNull class]]) This is the line where i got crash

                break;


            }
        }
    } @catch (NSException *exception) {

        [DeviceLoger log:[NSString stringWithFormat:@"Exception in ProcessdidTapMarker: %@",exception]];
    }
 }
   return YES;
}

У кого-нибудь есть идея?

Пожалуйста, помогите мне, потому что я очень долго сталкиваюсь с этой проблемой

Спасибо!
