从文档目录中获取图像

Question

大家好，我想从文档中提取所有图像并将其附加到单元格中。

我创建了此功能来将图像保存在didSelectItemAt

 func saveImage(image: UIImage, imageName: String) {

    let path = "yourProjectImages"
       let document = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first?.appendingPathComponent(path, isDirectory: true)



        let imageUrl = document!.appendingPathComponent("\(imageName).jpg", isDirectory: true)

        do {

                try UIImagePNGRepresentation(image)?.write(to: imageUrl, options: .atomic)
            } catch {

            print(error.localizedDescription)


            }

        }

我使用了它，就像我在didSelectItemAt中所说的那样

    override func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {


let selectedImage = images[indexPath.item]

saveImage(image: selectedImage, imageName: "\(selectedImage)")


}

it seems to add picture immediately in document after clicking on the picture

但是如何在我的rootController的HomeFeed中获取它们呢？

这些显示的照片是相册，我使用“照片”框架从相册中获取多张照片。
