ios - 保存照片和检索 Assets 时，应用程序图片中的 Swift Camera 不保存 GPS 信息？

Question

我正在使用相机和 UIImagePickerController 拍照，然后使用

将其保存到相册中

@objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    ImagePicker.dismiss(animated: true, completion: nil)
    photoChanged = true

    let image: UIImage = info[UIImagePickerControllerOriginalImage] as! UIImage
    let compressedImage = image.resizeWithWidth(width: 450)
    let ext: String = "JPEG"

    UIImageWriteToSavedPhotosAlbum(image, self, #selector(image(image:didFinishSavingWithError:contextInfo:)), nil)
    submittedPhoto = Photo(photo: compressedImage, ext: ext, key: nil, idx: nil, postId: post?.postId)

    if let cell = tableView.cellForRow(at: IndexPath(row: 1, section: 0)) as? SubmitHunterTVC {

        cell.addPhotoB.iconImageView.image = image
        cell.addPhotoB.iconImageView.contentMode = .scaleAspectFill
        cell.addPhotoB.clipsToBounds = true
    }
    tableView.reloadData()
}

当我检索 Assets 并检查位置时，我从 EXIF 和 Assets 中获得空的 {GPS} 信息。

有一个很好的答案 HERE ，下面是该答案中的一些代码，它可能需要更新为当前语法:

func addAsset(image: UIImage, location: CLLocation? = nil) {
    PHPhotoLibrary.shared().performChanges({
        // Request creating an asset from the image.
        let creationRequest = PHAssetChangeRequest.creationRequestForAsset(from: image)
        // Set metadata location
        if let location = location {
            creationRequest.location = location
        }
    }, completionHandler: { success, error in
        if !success { NSLog("error creating asset: \(error)") }
    })
}
