I take advantage of PHPicker for person to import pictures, however UIImage not assist the pic of .AVIF, so I wish to get the origin knowledge of .AVIF pic, that is my code:
func picker(_ picker: PHPickerViewController, didFinishPicking outcomes: [PHPickerResult]) {
picker.dismiss(animated: true)
for picture in outcomes {
loadImagePickerResult(picture: picture)
}
}
func loadImagePickerResult(picture: PHPickerResult) {
if picture.itemProvider.canLoadObject(ofClass: UIImage.self) {
picture.itemProvider.loadObject(ofClass: UIImage.self) { [weak self] newImage, error in
guard let self = self else { return }
if let _ = error {
} else if let needAddImage = newImage as? UIImage {
let imageItem = ContentImageItem()
imageItem.picture = needAddImage
self.viewModel.selectedImageList.append(imageItem)
DispatchQueue.fundamental.async {
self.scrollImageView.reloadData()
self.checkConfirmState()
}
}
}
} else if picture.itemProvider.hasItemConformingToTypeIdentifier(kUTTypeImage as String) {
picture.itemProvider.loadItem(forTypeIdentifier: kUTTypeImage as String, choices: nil) { [weak self] merchandise, error in
guard let self = self else { return }
guard let url = merchandise as? URL else { return }
var imageData: Knowledge?
do {
imageData = strive Knowledge(contentsOf: url, choices: [.mappedIfSafe, .alwaysMapped])
} catch {
}
guard let selectedImageData = imageData else { return }
/// selectedImageData is empty knowledge
}
} else {
}
}
Once I select .AVIF pic, itemProvider can load the picture by “kUTTypeImage” typeIdentifier, and success to get the native path of the pic, however once I use Knowledge(contentsOf: ) to learn the origin knowledge, I can solely get an empty knowledge. So, is there any downside with this code？Does anybody have expertise in dealing with this matter？
url path and empty knowledge
I take advantage of “NSData(contentsOf:” to get the origin knowledge, however nonetheless is empty.
