解除模态视图控制器在（iOS13.5 Xcode 11.5）中显示黑屏

从委托方法中取消此视图控制器，将显示一个黑屏

let cropViewController = CropViewController(image: images[0])
cropViewController.delegate = self

self.present(cropViewController, animated: true, completion: nil)

---

Xcode 11.5和iOS13.5在选择图像并进行裁剪后，我也遇到了同样的问题，只有黑屏出现

替换

func cropViewController(_ cropViewController: CropViewController,
                        didCropToImage image: UIImage,
                        withRect cropRect: CGRect,
                        angle: Int) {
    // 'image' is the newly cropped version of the original image
    cropViewController.dismiss(animated: true, completion: {
        self.setImageAndReloadRow(image: image)
    })

}

与

cropViewController.dismiss(animated: true, completion: nil).

let viewController = cropViewController.children.first! 
viewController.modalTransitionStyle = .coverVertical 
viewController.presentingViewController?.dismiss(animated: true, completion: nil)
