Swift 如何从UIImage中提取图像文件名

我有

，{16682500

}的名字，可以在画廊里拍照。但我需要字符串中的imagename。有人帮我解决swift 4中的问题吗？我给出了以下代码：

extension PhotoViewController: ImagePickerDelegate {
func wrapperDidPress(_ imagePicker: ImagePickerController, images: [UIImage]) {

}

func doneButtonDidPress(_ imagePicker: ImagePickerController, images: [UIImage]) {
    self.image = images[0]



    let navigati:PhotoDescriptorController = storyboard!.instantiateViewController(withIdentifier: StoryBoard.PhotoDescriptorController) as! PhotoDescriptorController

    navigati.imageDest = self.image
    self.navigationController?.pushViewController(navigati, animated: true)

    imagePicker.dismiss(animated: true, completion: nil)
}

func cancelButtonDidPress(_ imagePicker: ImagePickerController) {
    imagePicker.dismiss(animated: true, completion: nil)
}

您是否尝试过使用

Photo

framework获取imageName

参见此示例。

 func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        if let asset = info[UIImagePickerControllerPHAsset] as? PHAsset {
            let assetResources = PHAssetResource.assetResources(for: asset)

            print(assetResources.first!.originalFilename)
        }

        dismiss(animated: true, completion: nil)
    }

欢迎来到StackOverflow。请说明您进行过哪些研究，您已经尝试过哪些研究，编码示例等。阅读并更新您的问题。什么是

ImagePickerController

？

ImagePickerController

是您的协议？是的，ImagePickerController是协议@Enea Dumenow我们需要查看代码，您在哪里调用

委托。DonebuttondPress

我有这个图像选择器。扩展PhotoViewController:ImagePickerDelegate{func donebuttondPress（imagePicker:ImagePickerController，images:[UIImage]）{self.image=images[0]让navigati:PhotoDescriptorController=storyboard！。实例化EWController（标识符：storyboard.PhotoDescriptorController）as！PhotoDescriptorController navigati.imageDest=self.image self.navigationController？.pushViewController（navigati，动画：true）imagePicker.dismission（动画：true，完成：nil）}@Enea Dumey您可以更改此设置，并使用

didFinishPickingMediaWithInfo

发布您的代码，因为我们无法预测您使用了什么方法或如何编码。不，我必须这样做。请根据这些代码给出答案。@Enea Dume

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    if let picURL = info[UIImagePickerControllerReferenceURL] as? URL {
        let imgData = PHAsset.fetchAssets(withALAssetURLs: [picURL], options: nil)
        let asset = imgData.firstObject
        print(asset?.value(forKey: "filename"))

    }

    dismiss(animated: true, completion: nil)
}
