swift3 - Rápido Toma una foto y guárdala en la biblioteca de fotos.

ios10

Question

He estado buscando y no he podido encontrar la respuesta a esto. Tengo un botón "tomar una foto" y cuando se presiona, abre la cámara, tomas una foto y cuando seleccionas "Usar foto", quiero que se guarde en la biblioteca de fotos.
Puedo hacer todo menos guardar en la biblioteca, ¿puede alguien ayudarme?

Este es el código que tengo para abrir la cámara:

Answer 1

De hecho, puedes agregarlo a tu código y se guardará:

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 }

Answer 2

En Swift 3.0

@IBOutlet weak var userPhotoImageView: UIImageView!
var pickerController = UIImagePickerController()
var imageView = UIImage()

crea tus salidas de UIImageView y UIImagePickerController

     in viewDidLoad 

    let imageTapGesture = UITapGestureRecognizer(target: self, action: #selector(tapUserPhoto(_:)))
    imageTapGesture.delegate = self
    userPhotoImageView.addGestureRecognizer(imageTapGesture)
    imageTapGesture.numberOfTapsRequired = 1
    userPhotoImageView.isUserInteractionEnabled = true
    pickerController.delegate = self
    func tapUserPhoto(_ sender: UITapGestureRecognizer){
    let alertViewController = UIAlertController(title: "", message: "Choose your option", preferredStyle: .actionSheet)
    let camera = UIAlertAction(title: "Camera", style: .default, handler: { (alert) in
        self.openCamera()
    })
    let gallery = UIAlertAction(title: "Gallery", style: .default) { (alert) in
        self.openGallary()
    }
    let cancel = UIAlertAction(title: "Cancel", style: .cancel) { (alert) in

    }
    alertViewController.addAction(camera)
    alertViewController.addAction(gallery)
    alertViewController.addAction(cancel)
    self.present(alertViewController, animated: true, completion: nil)
}
  func openCamera() {
    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera) {
        pickerController.delegate = self
        self.pickerController.sourceType = UIImagePickerControllerSourceType.camera
        pickerController.allowsEditing = true
        self .present(self.pickerController, animated: true, completion: nil)
    }
    else {
        let alertWarning = UIAlertView(title:"Warning", message: "You don''t have camera", delegate:nil, cancelButtonTitle:"OK", otherButtonTitles:"")
        alertWarning.show()
    }
}
func openGallary() {
    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary) {
        pickerController.delegate = self
        pickerController.sourceType = UIImagePickerControllerSourceType.photoLibrary
        pickerController.allowsEditing = true
        self.present(pickerController, animated: true, completion: nil)
    }
}
public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    imageView = info[UIImagePickerControllerEditedImage] as! UIImage
    userPhotoImageView.contentMode = .scaleAspectFill
    userPhotoImageView.image = imageView
    dismiss(animated:true, completion: nil)
}
public func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    print("Cancel")
}

Aquí estoy usando tapgesture para hacer clic en UIImageView

import UIKit

class photoPickerController: UIViewController,UINavigationControllerDelegate{

@IBOutlet weak var imageTake: UIImageView!

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


@IBAction func takePhoto(_ sender: UIButton) {

    imagePicker =  UIImagePickerController()
    imagePicker.delegate = self
    imagePicker.sourceType = .camera
    present(imagePicker, animated: true, completion: nil)
}


@IBAction func saveToLibrary(_ sender: AnyObject) {
    UIImageWriteToSavedPhotosAlbum(imageTake.image!, self, #selector(image(_:didFinishSavingWithError:contextInfo:)), nil)
    }
}

extension photoPickerController :  UIImagePickerControllerDelegate  {

func image(_ image: UIImage, didFinishSavingWithError error: Error?, contextInfo: UnsafeRawPointer) {
    if let error = error {
        // we got back an error!
        let alert = UIAlertController(title: "Error", message: error.localizedDescription, preferredStyle: .alert)
        alert.addAction(UIAlertAction(title: "OK", style: .default))
        present(alert, animated: true)
    } else {
        let alert = UIAlertController(title: "Saved!", message: "Image saved successfully", preferredStyle: .alert)
        alert.addAction(UIAlertAction(title: "OK", style: .default))
        present(alert, animated: true)
    }
}

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

UIImage } }

Answer 4

Use el código de abajo para una imagen tomada de la Galería fotográfica y guarde dentro de la biblioteca de fotos.

Soporte de código para la versión Swift 3.1 y 4.0 :

Primero, tenemos que hacer la configuración de los permisos dentro del archivo .plist del proyecto: -

1) cámara

<key>NSCameraUsageDescription</key>
<string>This app will use camera.</string>

2) Fototeca

<key>NSPhotoLibraryUsageDescription</key>
<string>You can select photos to attach to reports.</string>

3) Guardar en Photo Library

<key>NSPhotoLibraryAddUsageDescription</key>
<string>Please allow access to save photo in your photo library</string>

Necesitamos abrir el archivo .pilst como un tipo de código fuente y luego agregar permisos dentro de -

Después de esto

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
    }

}
