I have been searching and unable to find the answer to this. I have a button "take a photo" and when pressed, it opens the camera, you take a photo and when you select "Use Photo", I want it saved to the photo library.
I am able to do all but save to the library, can someone help?
this is the code I have to open the camera:
Use below code for an image taken from Photo Gallery and save inside photo library.
Code Support for Swift 3.1 & 4.0 version:
First, we have to do the setup for Permissions inside Project's .plist file:-
1) Camera
<key>NSCameraUsageDescription</key>
<string>This app will use camera.</string>
2) Photo Library
<key>NSPhotoLibraryUsageDescription</key>
<string>You can select photos to attach to reports.</string>
3) Save to Photo Library
<key>NSPhotoLibraryAddUsageDescription</key>
<string>Please allow access to save photo in your photo library</string>
We need to open .pilst file as a Source code type then add permissions inside -
After That
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
}
}
Swift 4.2 Code update -
class ViewController: UIViewController, UINavigationControllerDelegate {
@IBOutlet weak var imageTake: UIImageView!
var imagePicker: UIImagePickerController!
enum ImageSource {
case photoLibrary
case camera
}
override func viewDidLoad() {
super.viewDidLoad()
}
//MARK: - Take image
@IBAction func takePhoto(_ sender: UIButton) {
guard UIImagePickerController.isSourceTypeAvailable(.camera) else {
selectImageFrom(.photoLibrary)
return
}
selectImageFrom(.camera)
}
func selectImageFrom(_ source: ImageSource){
imagePicker = UIImagePickerController()
imagePicker.delegate = self
switch source {
case .camera:
imagePicker.sourceType = .camera
case .photoLibrary:
imagePicker.sourceType = .photoLibrary
}
present(imagePicker, animated: true, completion: nil)
}
//MARK: - Saving Image here
@IBAction func save(_ sender: AnyObject) {
guard let selectedImage = imageTake.image else {
print("Image not found!")
return
}
UIImageWriteToSavedPhotosAlbum(selectedImage, self, #selector(image(_:didFinishSavingWithError:contextInfo:)), nil)
}
//MARK: - Add image to Library
@objc func image(_ image: UIImage, didFinishSavingWithError error: Error?, contextInfo: UnsafeRawPointer) {
if let error = error {
// we got back an error!
showAlertWith(title: "Save error", message: error.localizedDescription)
} else {
showAlertWith(title: "Saved!", message: "Your image has been saved to your photos.")
}
}
func showAlertWith(title: String, message: String){
let ac = UIAlertController(title: title, message: message, preferredStyle: .alert)
ac.addAction(UIAlertAction(title: "OK", style: .default))
present(ac, animated: true)
}
}
extension ViewController: UIImagePickerControllerDelegate{
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]){
imagePicker.dismiss(animated: true, completion: nil)
guard let selectedImage = info[.originalImage] as? UIImage else {
print("Image not found!")
return
}
imageTake.image = selectedImage
}
}
In Swift 3.0
class PhotoViewController: UIViewController, UIGestureRecognizerDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate
create your UIImageView outlets and UIImagePickerController
@IBOutlet weak var userPhotoImageView: UIImageView!
var pickerController = UIImagePickerController()
var imageView = UIImage()
Here i am using tapgesture for clicking on UIImageView
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")
}
Anand Nimje's answer updated for Swift 4
class ImageCaptureViewController: UIViewController,UINavigationControllerDelegate, UIImagePickerControllerDelegate {
@IBOutlet weak var takeImage: UIImageView!
var imagePicker: UIImagePickerController!
@IBAction func takePhoto(_ sender: UIButton) {
imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = .camera
present(imagePicker, animated: true, completion: nil)
}
@IBAction func savePhoto(_ sender: UIButton) {
UIImageWriteToSavedPhotosAlbum(takeImage.image!, self, #selector(image(_:didFinishSavingWithError:contextInfo:)), nil)
}
@objc func image(_ image: UIImage, didFinishSavingWithError error: Error?, contextInfo: UnsafeRawPointer) {
if let error = 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)
}
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
imagePicker.dismiss(animated: true, completion: nil)
takeImage.image = info[UIImagePickerControllerOriginalImage] as? UIImage
}
}
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
}
}
In fact You can just add it to your code and it will save:
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
}
