ios - 在 UIImage 中加载 UIViewController

Question

我正在使用滑动手势代码来翻转图像，它调用此代码：

- (void)rightSwipeHandle:(UISwipeGestureRecognizer*)gestureRecognizer {
    for (UIImageView *imageView in imageArray)
    {

        if (([imageView isKindOfClass:[UIImageView class]] && imageView.tag == ((UISwipeGestureRecognizer *)gestureRecognizer).view.tag))
        {
            [UIView transitionWithView:imageView duration:0.5
                   options:UIViewAnimationOptionTransitionFlipFromRight animations:^{
                       //imageView.image = secondImage;
                   } completion:^(BOOL f){
                       UIStoryboard *sb = [UIStoryboard storyboardWithName:@"PhotoViewControllerStoryboard" bundle:nil];
                       UIViewController *vc = [sb instantiateInitialViewController];
                       vc.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
                       [self presentViewController:vc animated:YES completion:NULL];
                       vc.view.frame = CGRectMake(343, 163, 316, 546.5);

                }
            ];
        }
    }
}

翻转可以正常工作，但是当动画结束时，视图控制器会在黑色背景中加载。UIImage如果它是图像的背面，我希望它以类似的方式加载。我怎样才能做到这一点？？
