ios - example - Cómo utilizar UIImagePickerController para la cámara y la biblioteca de fotos al mismo tiempo en Swift

uiimagepickercontroller swift 4 example

Question

Utilizo UIImagePickerController para tomar una foto con la cámara del iPhone.

Quiero mostrar dos "tomar una foto" y "elegir una foto".

Mi código

imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = .camera
//imagePicker.sourceType = .PhotoLibrary
presentViewController(imagePicker, animated: true, completion: nil)

Intenté usar imagePicker.sourceType = .Camera y imagePicker.sourceType = .Camera imagePicker.sourceType = .PhotoLibrary para hacer esto, pero no funciona ...

Gracias

Swift 4 +:

Hoja de acción con cámara y galería:

//MARK:- Image Picker
@IBAction func imagePickerBtnAction(selectedButton: UIButton)
{
let alert = UIAlertController(title: "Choose Image", message: nil, preferredStyle: .actionSheet)
alert.addAction(UIAlertAction(title: "Camera", style: .default, handler: { _ in
self.openCamera()
}))
alert.addAction(UIAlertAction(title: "Gallery", style: .default, handler: { _ in
self.openGallery()
}))
alert.addAction(UIAlertAction.init(title: "Cancel", style: .cancel, handler: nil))
self.present(alert, animated: true, completion: nil)
}

Funcionalidad del selector de imagen de la cámara:

func openCamera()
{
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera) {
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = UIImagePickerControllerSourceType.camera
imagePicker.allowsEditing = false
self.present(imagePicker, animated: true, completion: nil)
}
else
{
let alert = UIAlertController(title: "Warning", message: "You don''t have camera", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
self.present(alert, animated: true, completion: nil)
}
}

Galería de funciones de selección de imágenes:

 func openGallery()
{
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary){
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.allowsEditing = true
imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary
self.present(imagePicker, animated: true, completion: nil)
}
else
{
let alert = UIAlertController(title: "Warning", message: "You don''t have perission to access gallery.", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
self.present(alert, animated: true, completion: nil)
}
}

Delegado de ImagePicker:

//MARK:-- ImagePicker delegate
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
// imageViewPic.contentMode = .scaleToFill
}
picker.dismiss(animated: true, completion: nil)
}

Answer 2

Crea un controlador de vista y agrega un botón e imagen en el guión gráfico.

agregar los protocolos UIImagePickerControllerDelegate, UINavigationControllerDelegate en el controlador de vista

botón de acción de la cámara introduzca el siguiente código

let imagePickerController = UIImagePickerController()
imagePickerController.delegate = self
let actionsheet = UIAlertController(title: "Photo Source", message: "Choose A Sourece", preferredStyle: .actionSheet)
actionsheet.addAction(UIAlertAction(title: "Camera", style: .default, handler: { (action:UIAlertAction)in
if UIImagePickerController.isSourceTypeAvailable(.camera){
imagePickerController.sourceType = .camera
self.present(imagePickerController, animated: true, completion: nil)
}else
{
print("Camera is Not Available")
}
}))
actionsheet.addAction(UIAlertAction(title: "Photo Library", style: .default, handler: { (action:UIAlertAction)in
imagePickerController.sourceType = .photoLibrary
self.present(imagePickerController, animated: true, completion: nil)
}))
actionsheet.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
self.present(actionsheet,animated: true, completion: nil)

Añadir la siguiente función en el controlador de vista

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

en info.plist agregar fila con

 Privacy - Photo Library Usage Description
Privacy - Camera Usage Description

Importe UIImagePickerControllerDelegate y cree una variable para asignar UIImagePickerController var imagePicker = UIImagePickerController() y establezca imagePicker.delegate = self .

Cree una hoja de acción para mostrar las opciones para ''Cámara'' y ''Biblioteca de fotos''.

En su botón, haga clic en la acción:

@IBAction func buttonOnClick(_ sender: UIButton)
{
self.btnEdit.setTitleColor(UIColor.white, for: .normal)
self.btnEdit.isUserInteractionEnabled = true
let alert = UIAlertController(title: "Choose Image", message: nil, preferredStyle: .actionSheet)
alert.addAction(UIAlertAction(title: "Camera", style: .default, handler: { _ in
self.openCamera()
}))
alert.addAction(UIAlertAction(title: "Gallery", style: .default, handler: { _ in
self.openGallary()
}))
alert.addAction(UIAlertAction.init(title: "Cancel", style: .cancel, handler: nil))
/*If you want work actionsheet on ipad
then you have to use popoverPresentationController to present the actionsheet,
otherwise app will crash on iPad */
switch UIDevice.current.userInterfaceIdiom {
case .pad:
alert.popoverPresentationController?.sourceView = sender
alert.popoverPresentationController?.sourceRect = sender.bounds
alert.popoverPresentationController?.permittedArrowDirections = .up
default:
break
}
self.present(alert, animated: true, completion: nil)
}
func openCamera()
{
if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.camera))
{
imagePicker.sourceType = UIImagePickerControllerSourceType.camera
imagePicker.allowsEditing = true
self.present(imagePicker, animated: true, completion: nil)
}
else
{
let alert = UIAlertController(title: "Warning", message: "You don''t have camera", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
self.present(alert, animated: true, completion: nil)
}
}
func openGallary()
{
imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary
imagePicker.allowsEditing = true
self.present(imagePicker, animated: true, completion: nil)
}

Answer 4

establecer delegado como

UIImagePickerControllerDelegate,UINavigationControllerDelegate

tome una vista de imagen para que podamos mostrar la imagen seleccionada / capturada:

@IBOutlet weak var imageViewPic: UIImageView!

Para capturar una nueva imagen usando la cámara del dispositivo:

if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera) {
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = UIImagePickerControllerSourceType.camera
imagePicker.allowsEditing = false
self.present(imagePicker, animated: true, completion: nil)
}

Para seleccionar la foto de la galería:

if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary){
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.allowsEditing = true
imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary
self.present(imagePicker, animated: true, completion: nil)
}

Este es el método delegado:

 //MARK: - ImagePicker delegate
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
// imageViewPic.contentMode = .scaleToFill
imageViewPic.image = pickedImage
}
picker.dismiss(animated: true, completion: nil)
}

establece el permiso para acceder a la cámara y la foto en info.plist como:

<key>NSCameraUsageDescription</key>
<string>This app will use camera</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>You can select photo</string>

100% funcionando y probado.
