ios - 关闭模态视图 Controller 在(iOS13.5 Xcode 11.5)中显示黑屏

Question

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

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

从委托(delegate)方法中关闭此 View Controller ，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

Answer 1

选择图像并裁剪后我也遇到了同样的问题，只有黑屏出现。
代替

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

和

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