I use PHPicker for user to import photos, but UIImage not support the pic of .AVIF, so I want to get the origin data of .AVIF pic, this is my code:
func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
picker.dismiss(animated: true)
for image in results {
loadImagePickerResult(image: image)
}
}
func loadImagePickerResult(image: PHPickerResult) {
if image.itemProvider.canLoadObject(ofClass: UIImage.self) {
image.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.image = needAddImage
self.viewModel.selectedImageList.append(imageItem)
DispatchQueue.main.async {
self.scrollImageView.reloadData()
self.checkConfirmState()
}
}
}
} else if image.itemProvider.hasItemConformingToTypeIdentifier(kUTTypeImage as String) {
image.itemProvider.loadItem(forTypeIdentifier: kUTTypeImage as String, options: nil) { [weak self] item, error in
guard let self = self else { return }
guard let url = item as? URL else { return }
var imageData: Data?
do {
imageData = try Data(contentsOf: url, options: [.mappedIfSafe, .alwaysMapped])
} catch {
}
guard let selectedImageData = imageData else { return }
/// selectedImageData is empty data
}
} else {
}
}
When I choose .AVIF pic, itemProvider can load the image by "kUTTypeImage" typeIdentifier, and success to get the local path of the pic, but when I use Data(contentsOf: ) to read the origin data, I can only get an empty data. So, is there any problem with this code？Does anyone have experience in handling this matter？
"FileManager.default.contents(atPath: url.path)" and "NSData(contentsOf" is also return empty Data
