J'ai cherché et incapable de trouver la réponse à cette question. J'ai un bouton "prendre une photo" et lorsque vous appuyez dessus, il ouvre l'appareil photo, vous prenez une photo et lorsque vous sélectionnez "Utiliser la photo", je veux l'enregistrer dans la bibliothèque de photos.
Je peux tout faire sauf enregistrer dans la bibliothèque. Quelqu'un peut-il aider?
Utilisez le code ci-dessous pour une image extraite de la Galerie de photos et enregistrez-le dans la photothèque.
Prise en charge du code pour Swift 3.1 & 4.0 version:
Tout d'abord, nous devons faire la configuration pour Autorisations dans le pliste du projet . fichier:-
1) Caméra
<key>NSCameraUsageDescription</key>
<string>This app will use camera.</string>
2) Photothèque
<key>NSPhotoLibraryUsageDescription</key>
<string>You can select photos to attach to reports.</string>
3) Enregistrer dans la photothèque
<key>NSPhotoLibraryAddUsageDescription</key>
<string>Please allow access to save photo in your photo library</string>
Il faut ouvrir le fichier . Pilst en tant que code source puis ajouter autorisations à l'intérieur de -

En fait, vous pouvez simplement l’ajouter à votre code pour économiser:
UIImageWriteToSavedPhotosAlbum(/* your image */, self, #selector(image(_:didFinishSavingWithError:contextInfo:)), nil)
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
imagePicker.dismiss(animated: true, completion: nil)
imageTake.image = info[UIImagePickerControllerOriginalImage] as? UIImage
}
