swift Prendre une photo et l'enregistrer dans une photothèque

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?

c'est le code que je dois ouvrir la caméra: enter image description here

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 -

open .plist file


Après ça


import UIKit

class ViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate  {

    @IBOutlet weak var imageTake: UIImageView!

  var imagePicker: UIImagePickerController!
    override func viewDidLoad() {
        super.viewDidLoad()
    }

    //MARK: - Take image
    @IBAction func takePhoto(_ sender: UIButton) {
        imagePicker =  UIImagePickerController()
        imagePicker.delegate = self
        imagePicker.sourceType = .camera
        present(imagePicker, animated: true, completion: nil)
    }

    //MARK: - Saving Image here
    @IBAction func save(_ sender: AnyObject) {
        UIImageWriteToSavedPhotosAlbum(imageTake.image!, self, #selector(image(_:didFinishSavingWithError:contextInfo:)), nil)
    }

    //MARK: - Add image to Library
    func image(_ image: UIImage, didFinishSavingWithError error: Error?, contextInfo: UnsafeRawPointer) {
        if let error = error {
            // we got back an error!
            let ac = UIAlertController(title: "Save error", message: error.localizedDescription, preferredStyle: .alert)
            ac.addAction(UIAlertAction(title: "OK", style: .default))
            present(ac, animated: true)
        } else {
            let ac = UIAlertController(title: "Saved!", message: "Your altered image has been saved to your photos.", preferredStyle: .alert)
            ac.addAction(UIAlertAction(title: "OK", style: .default))
            present(ac, animated: true)
        }
    }

    //MARK: - Done image capture here
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
         imagePicker.dismiss(animated: true, completion: nil)
        imageTake.image = info[UIImagePickerControllerOriginalImage] as? UIImage
    }

}

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
