ios - 关闭(iOS13.5 Xcode 11.5)中的模态视图 Controller 显示黑屏

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

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

从委托方法中取消此视图控制器，显示黑屏

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)
    })

}

Xcode 11.5和iOS13.5

最佳答案

选择图像并裁剪后，我也遇到了同样的问题，只有黑屏出现了。
更换

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

用

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