UIWindow subview disappear immediately on ios 13

Question

I am upgrading my app to use iOS 13. I have been using a UIWindow to add image to the current screen. However in ios 13 the image will appear, but then disappear straight away. I tried building in previous version, which is ios 12.2, and it's working fine.

this is my code:

 UIWindow *currentWindow = [UIApplication sharedApplication].keyWindow;

    UIImage *image = [UIImage imageNamed:@"test_badge" inBundle:VTBundle compatibleWithTraitCollection:nil];
    UIImageView *badgeImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, [currentWindow bounds].size.height-115, 115, 115)];
    badgeImageView.tag =100101;
    badgeImageView.image = image;

    [currentWindow addSubview:badgeImageView];
