Question

我使用UIImagePickerController选择图片我想要所选图片的路径，但我无法获得它。

我在代码中尝试的内容：

func handleImg() {
    let picker = UIImagePickerController()
    picker.delegate = self
    picker.allowsEditing = true
    present(picker, animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    var selectedImageFromPicer : UIImage?
    if let editedImage = info["UIImagePickerControllerEditedImage"] as? UIImage {
        selectedImageFromPicer = editedImage
    } else if let originalImage = info["UIImagePickerControllerOriginalImage"] as? UIImage {

        selectedImageFromPicer = originalImage
    }

    if let selectedImage = selectedImageFromPicer {
        img.image = selectedImage
    }
    if let imageURL = info[UIImagePickerControllerReferenceURL] as? URL {

        let result = PHAsset.fetchAssets(withALAssetURLs: [imageURL], options: nil)
        let asset = result.firstObject
        var imgStr = asset?.value(forKey: "filename")
        print(imgStr!)
    }
    dismiss(animated: true, completion: nil)
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        print("canceled picker")
        dismiss(animated: true, completion: nil)
    }
}

通过上面的代码，我只能得到图像的名称。我想要形象之路。

Answer 1

如果您打印info对象，您将看到用于访问此词典值的所有可用键。图像路径键为UIImagePickerControllerImageURL

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    guard let imageUrl = info["UIImagePickerControllerImageURL"] as? URL else {
        return
    }
    print(imageUrl.path) // prints the path
    picker.dismiss(animated: true, completion: nil)
}

以下代码可帮助您获取图像路径。

显示UIImagePickerController的代码。

@IBAction func showPicker(_ sender: Any) {

    let picker = UIImagePickerController()
    picker.delegate = self
    picker.sourceType = UIImagePickerControllerSourceType.savedPhotosAlbum
    picker.allowsEditing = false
    present(picker, animated: true, completion: nil)
}

委托方法didFinishPickingMediaWithInfo。

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let imageUrl          = info[UIImagePickerControllerReferenceURL] as! NSURL
    let imageName         = imageUrl.lastPathComponent
    let documentDirectory = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first!
    let photoURL          = NSURL(fileURLWithPath: documentDirectory)
    let localPath         = photoURL.appendingPathComponent(imageName!) 
    //Check these values

    self.dismiss(animated: true, completion: nil);

}

没有获得图像路径
