【中文标题】保存照片并检索资产时,应用图片中的 Swift Camera 不保存 GPS 信息?【英文标题】:Swift Camera in app picture not saving GPS information when photo is saved and the asset is retrieved? 【发布时间】:2018-03-18 22:20:15 【问题描述】:我正在用相机和 UIImagePickerController 拍照,然后用
将它保存到相册@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()
当我检索资产并检查位置时,我从 EXIF 和资产中获得了空的 GPS 信息。

【参考方案1】:有一个很好的答案HERE,下面是该答案的一些代码,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)")
)
