How can I make this imagePickerController able to accept edited images?

如何让这个 imagePickerController 能够接受编辑后的图片?

选择图像并对其进行调整(放大和缩小)并选择完成时,图像会恢复到原始状态。我可以在我的代码中添加什么来保存缩放后的图像并将其显示在我的图像视图中?

到目前为止,以下是我的代码:

let cameraRollAction = UIAlertAction(title: "Camera Roll", style: .default) { (action) in
    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary) {
        let picker = UIImagePickerController()
        picker.delegate = self
        picker.allowsEditing = true
        picker.mediaTypes = [kUTTypeImage as String]
        picker.sourceType = UIImagePickerControllerSourceType.photoLibrary
        self.present(picker, animated: true, completion: nil)
        self.newPic = false
    }

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let mediaType = info[UIImagePickerControllerMediaType] as! NSString
    if mediaType.isEqual(to: kUTTypeImage as String) {
        let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage
        profileImageView.image = selectedImage
        if newPic == true {
            UIImageWriteToSavedPhotosAlbum(selectedImage, self, #selector(imageError), nil)
        }
    }
    self.dismiss(animated: true, completion: nil)
}

而不是

UIImagePickerControllerOriginalImage

使用

UIImagePickerControllerEditedImage
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let mediaType = info[UIImagePickerControllerMediaType] as! NSString
if mediaType.isEqual(to: kUTTypeImage as String) {
    let selectedImage = info[UIImagePickerControllerEditedImage] as! UIImage ?? info[UIImagePickerControllerOriginalImage] as! UIImage // will return original image if edited image is not available
    profileImageView.image = selectedImage
    if newPic == true {
        UIImageWriteToSavedPhotosAlbum(selectedImage, self, #selector(imageError), nil)
    }
}
self.dismiss(animated: true, completion: nil)

}
