App crashes when opening a camera on Xcode Swift [duplicate] - ios

This question already has answers here:
Request Permission for Camera and Library in iOS 10 - Info.plist
(10 answers)
Closed 5 years ago.
I'm a beginner on Swift and can't really figure out why it crashes.
Simulator is fine (it's just giving me a message that device doesn't have camera)
But when I open it on my actual phone the app crashes. (Using iphone x with 11.2.6)
Every other functions are fine but camera function.
How do I fix it?
Thanks in advance!

You have to add the below permission in Info.plist. Permission in Info.plist
Camera :
Key : Privacy - Camera Usage Description
Value : $(PRODUCT_NAME) camera use
Photo :
Key : Privacy - Photo Library Usage Description
Value : $(PRODUCT_NAME) photo use

How to save Image in String to Realm from UIImagePickerController?

PickerController class, where I create the UIImagePickerController:
public protocol ImagePickerDelegate: class {
func didSelect(image: UIImage?)
}
open class ImagePicker: NSObject {
private let pickerController: UIImagePickerController
private weak var presentationController: UIViewController?
private weak var delegate: ImagePickerDelegate?
public init(presentationController: UIViewController, delegate: ImagePickerDelegate) {
self.pickerController = UIImagePickerController()
super.init()
self.presentationController = presentationController
self.delegate = delegate
self.pickerController.delegate = self
self.pickerController.allowsEditing = true
self.pickerController.mediaTypes = ["public.image"]
}
private func action(for type: UIImagePickerController.SourceType, title: String) -> UIAlertAction? {
guard UIImagePickerController.isSourceTypeAvailable(type) else {
return nil
}
return UIAlertAction(title: title, style: .default) { [unowned self] _ in
self.pickerController.sourceType = type
self.presentationController?.present(self.pickerController, animated: true)
}
}
public func present(from sourceView: UIView) {
let alertController = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)
if let action = self.action(for: .camera, title: "Сделать фото") {
alertController.addAction(action)
}
if let action = self.action(for: .photoLibrary, title: "Выбрать из галереи") {
alertController.addAction(action)
}
alertController.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
if UIDevice.current.userInterfaceIdiom == .pad {
alertController.popoverPresentationController?.sourceView = sourceView
alertController.popoverPresentationController?.sourceRect = sourceView.bounds
alertController.popoverPresentationController?.permittedArrowDirections = [.down, .up]
}
self.presentationController?.present(alertController, animated: true)
}
private func pickerController(_ controller: UIImagePickerController, didSelect image: UIImage?) {
controller.dismiss(animated: true, completion: nil)
self.delegate?.didSelect(image: image)
}
}
extension ImagePicker: UIImagePickerControllerDelegate {
public func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
self.pickerController(picker, didSelect: nil)
}
public func imagePickerController(_ picker: UIImagePickerController,
didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]) {
guard let image = info[.editedImage] as? UIImage else {
return self.pickerController(picker, didSelect: nil)
}
self.pickerController(picker, didSelect: image)
}
}
extension ImagePicker: UINavigationControllerDelegate {
}
I guess, in didFinishPickingMediaWithInfo i should do something, but don't understand what exactly
class, where i work with pickerController:
class AddPlaneImageController: AddPlaneImageView {
var imagePicker: ImagePicker!
override func viewDidLoad() {
super.viewDidLoad()
self.imagePicker = ImagePicker(presentationController: self, delegate: self)
}
#IBAction func showImagePicker(_ sender: UIButton) {
self.imagePicker.present(from: sender)
}
#IBAction func saveButton(_ sender: Any) {
RealmModel.shared.addPlaneImage(planeImage: "", aircompany: "") // here I'm supposed to save this image as String to Realm
}
}
extension AddPlaneImageController: ImagePickerDelegate {
func didSelect(image: UIImage?) {
self.planeImage.image = image
}
}
So, basically I don't understand, how I can turn UIImage() into String() and save it as String() too. I marked in the code, where I am supposed to do it

UIImagepickercontroller - Camera is not working

This is my imagepicker class
import UIKit
public protocol ImagePickerDelegate: AnyObject {
func didSelect(image: UIImage?)
}
open class ImagePicker: NSObject {
private let pickerController: UIImagePickerController
private weak var presentationController: UIViewController?

if let wnwrappedImage = image , let imageData = wnwrappedImage.jpegData(compressionQuality: 0){
self.changePhotoView.profileImageView.image = wnwrappedImage
imageParams = ["group_photo" : imageData]
}
}
}
It's working fine for photo gallery and saved photo album but When I try to open camera, it's giving me error as follows
**[Camera] Failed to read exposureBiasesByMode dictionary: Error Domain=NSCocoaErrorDomain Code=4864 "*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: data is NULL" UserInfo={NSDebugDescription=*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: data is NULL}**
Any help would be appreciated

My segue is not executed after taking a pic

I'm developing an app which uses a camera and then the photo is supposed to be sent to another ViewController, but i'm not sure if it maybe the segue is not be able to there or that it is just be executed, but when I confirm the photo my app crashed and no errors are showed on my log.
This is the camera View controller
import UIKit
import AVFoundation
class ViewController: UIViewController ,
UIImagePickerControllerDelegate, UINavigationControllerDelegate{
var img = UIImageView()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
#IBAction func photo(_ sender: Any) {
checkCameraPermissions()
}
private func checkCameraPermissions() {
let status = AVCaptureDevice.authorizationStatus(for: .video)
switch status {
case .authorized:
print("1")
presentPicker()
case .notDetermined:
print("2")
askPermision()
case .denied:
print("3")
// user denied access
self.permissionDenied()
case .restricted:
print("Error restricted")
}
}
private func presentPicker() {
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerController.SourceType.camera) {
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = UIImagePickerController.SourceType.camera
imagePicker.allowsEditing = false
self.present(imagePicker, animated: true, completion: nil)
}
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let pickedImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage{
img.image = pickedImage
}
performSegue(withIdentifier: "captured", sender: nil)
}
private func askPermision(){
AVCaptureDevice.requestAccess(for: AVMediaType.video) {granted in
if granted {
self.presentPicker()
} else {
print("Denied")
}
}
}
private func permissionDenied() {
let alert = UIAlertController(title: "Access to camera is denied", message: "You have denied the access to the camera. Would you like to able it?", preferredStyle: .alert)
let actionOK = UIAlertAction(title: "Ok", style: .default) { (UIAlertAction) in
self.askPermision()
}
let cancel = UIAlertAction(title: "Cancel", style: .default) { (action) in
print("Cancel")
}
alert.addAction(actionOK)
alert.addAction(cancel)
present(alert, animated : true, completion: nil)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if(segue.identifier == "captured"){
let vc = segue.destination as! ImageReportedVC
vc.imgAux = img.image!
}
}
}
And then, this is the 2nd VC which doesn't appear. I believe the segue shouldn't be done there or something, but if you put it in another part of the code, it is executed before taking the photo.
import UIKit
class ImageReportedVC: UIViewController {
var imgAux = UIImage()
#IBOutlet weak var imgReported: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
imgReported.image = imgAux
// Do any additional setup after loading the view.
}
}
Thanks
You need to dismiss the picker
picker.dismiss(animated:true) {
self.performSegue(withIdentifier: "captured", sender: nil)
}

UIImagePickerController what is the right approach to avoid error Code=13 "query cancelled"

I'm implementing a photopicker in my project and it works or not, with the same code, depending the way I implement it. In my first approach I was using a custom UIAlertAction class and doing all the stuff in there, to have my main controller lighter, but the picker delegate was never called, instead it prints an error message in the console ([discovery] errors encountered while discovering extensions: Error Domain=PlugInKit Code=13 "query cancelled" UserInfo={NSLocalizedDescription=query cancelled}) and I would like to discuss if the way I were implementing the picker was right or wrong and why? Or if it's a bug from apple. I've been googling for a while and checking all the related questions in stack overflow, and anything has worked for me except to put the picker code in my main controller.
Here is the code of my main controller, when it was not calling the delegate:
First approach that give me error and don't call delegates
import UIKit
import MobileCoreServices
import Photos
class ViewController: UIViewController {
#IBOutlet weak var lblMain: UILabel!
#IBOutlet weak var buttonsBottom: NSLayoutConstraint!
#IBOutlet weak var imgFromUser: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
hideButtons()
}
override func viewDidAppear(_ animated: Bool) {
showButtons()
checkPermission()
}
func checkPermission() {
let photoAuthorizationStatus = PHPhotoLibrary.authorizationStatus()
switch photoAuthorizationStatus {
case .authorized: print("Access is granted by user")
case .notDetermined: PHPhotoLibrary.requestAuthorization({
(newStatus) in
print("status is \(newStatus)")
if newStatus == PHAuthorizationStatus.authorized { print("success") }
})
case .restricted: print("User do not have access to photo album.")
case .denied: print("User has denied the permission.")
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func hideButtons()
{
buttonsBottom.constant += self.view.frame.size.height * 0.15
}
func showButtons(){
UIView.animate(withDuration: 0.5) {
}
UIView.animate(withDuration: 0.5, animations: {
self.buttonsBottom.constant = 0
self.view.layoutIfNeeded()
}) { (completed) in
self.lblMain.text = firstController.lblMain
}
}
#IBAction func addImagePressed(_ sender: Any) {
let alertViewController : AlertAction = AlertAction.init(controller: self, type: .photoGallery)
self.present((alertViewController.setType(alert: .photoGallery)), animated: true, completion: nil)
}
}
And this is my custom AlertAction class, it implements the picker & navigation delegate, creates the UIImagePickerController, sets the delegate to it, creates the alert action and set it to present the main view controller, adds it to a UIAlertController and gets returned to the main view controller which present it:
import UIKit
import Photos
class AlertAction: UIAlertAction {
var destinationController : ViewController?
var imagePicker = UIImagePickerController()
convenience init(controller : ViewController, type : type) {
self.init()
destinationController = controller
//Init picker
imagePicker.delegate = self
imagePicker.sourceType = type == .photoGallery ? UIImagePickerControllerSourceType.photoLibrary : UIImagePickerControllerSourceType.camera
imagePicker.allowsEditing = false
}
enum type {
case camera
case photoGallery
}
var alertType : type = .camera
func setType(alert : type) -> UIAlertController {
alertType = alert
return alertType == .camera ? newAlert() : newAlert()
}
func newAlert() -> UIAlertController{
//set alert text
let alertText = alertType == .camera ? AlertText.typeCamera : AlertText.typeGalery
let myAlert = UIAlertController(title: AlertText.title, message: "", preferredStyle: .actionSheet)
if alertType == .camera {
myAlert.addAction(getCameraAction(alertText: alertText))
return myAlert
}
else{
myAlert.addAction(getGalleryAction(alertText: alertText))
return myAlert
}
}
func getCameraAction(alertText : String) -> UIAlertAction{
let cameraAction = UIAlertAction(title : alertText, style : .default) { (action) in
if UIImagePickerController.isSourceTypeAvailable(.camera) {
self.destinationController!.present(self.imagePicker, animated: true, completion: nil)
}
}
return cameraAction
}
func getGalleryAction(alertText : String) -> UIAlertAction{
let photoLibraryAction = UIAlertAction(title: alertText, style: .default) { (action) in
if UIImagePickerController.isSourceTypeAvailable(.photoLibrary) {
self.destinationController!.present(self.imagePicker, animated: true, completion: nil)
}
}
return photoLibraryAction
}
}
extension AlertAction : UIImagePickerControllerDelegate {
#objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let mediaType = info[UIImagePickerControllerMediaType] as! NSString
if mediaType.isEqual(to: kCIAttributeTypeImage as String){
destinationController!.imgFromUser.image = info[UIImagePickerControllerOriginalImage] as? UIImage
}
destinationController!.dismiss(animated: true, completion: nil)
}
#objc func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
destinationController!.dismiss(animated: true, completion: nil)
}
}
extension AlertAction : UINavigationControllerDelegate {
}
After reading a while, I've been trying all the posible solutions in this custom class but nothing worked.
Then I tried to implement a picker creation method in my main view controller and it worked.
So my question is very simple, why the delegate methods get called only if I do all the coding stuff in the main view controller but don't work in a custom class?
Here is the code that I'm currently using and works:
Second approach that works, all the code in the same ViewController
import UIKit
import MobileCoreServices
import Photos
class ViewController: UIViewController {
#IBOutlet weak var lblMain: UILabel!
#IBOutlet weak var buttonsBottom: NSLayoutConstraint!
#IBOutlet weak var imgFromUser: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
hideButtons()
}
override func viewDidAppear(_ animated: Bool) {
showButtons()
checkPermission()
}
func checkPermission() {
let photoAuthorizationStatus = PHPhotoLibrary.authorizationStatus()
switch photoAuthorizationStatus {
case .authorized: print("Access is granted by user")
case .notDetermined: PHPhotoLibrary.requestAuthorization({
(newStatus) in
print("status is \(newStatus)")
if newStatus == PHAuthorizationStatus.authorized { print("success") }
})
case .restricted: print("User do not have access to photo album.")
case .denied: print("User has denied the permission.")
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func hideButtons()
{
buttonsBottom.constant += self.view.frame.size.height * 0.15
}
func showButtons(){
UIView.animate(withDuration: 0.5) {
}
UIView.animate(withDuration: 0.5, animations: {
self.buttonsBottom.constant = 0
self.view.layoutIfNeeded()
}) { (completed) in
self.lblMain.text = firstController.lblMain
}
}
#IBAction func addImagePressed(_ sender: Any) {
self.present(addPicker(), animated: true, completion: nil)
}
//MARK: Picker methods
func addPicker()->UIAlertController{
let alertText = AlertText.typeGalery
let myAlert = UIAlertController(title: AlertText.title, message: "", preferredStyle: .actionSheet)
let cameraAction = UIAlertAction(title : alertText, style : .default) { (action) in
if UIImagePickerController.isSourceTypeAvailable(.photoLibrary) {
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = .photoLibrary
imagePicker.allowsEditing = true
self.present(imagePicker, animated: true, completion: nil)
}
}
myAlert.addAction(cameraAction)
return myAlert
}
}
extension ViewController : UIImagePickerControllerDelegate {
#objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let mediaType = info[UIImagePickerControllerMediaType] as! NSString
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage{
self.imgFromUser.image = image
}
if mediaType.isEqual(to: kCIAttributeTypeImage as String){
self.imgFromUser.image = info[UIImagePickerControllerOriginalImage] as? UIImage
}
self.dismiss(animated: true, completion: nil)
}
#objc func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
self.dismiss(animated: true, completion: nil)
}
}
extension ViewController : UINavigationControllerDelegate {
}
Update: the error [discovery] errors encountered while discovering extensions: Error Domain=PlugInKit Code=13 "query cancelled" UserInfo={NSLocalizedDescription=query cancelled} still appears in my second implementation, but only when I remove #objc before the picker delegate method and environement varibable OS_ACTIVITY_MODE = disable is not set, but the code still works anda the delegates are called correctly (in the second implementation) so basically this error is not related with the code functionality and don't describe anything useful

Unresolved identifier error 'email'

This is related to a previous question that was solved (See here: Sharing variables). I saw nothing that addresses what to do if your variable still isn't being recognized but your code to pass the variable appears solid.
I'm getting an unresolved identifier error 'email' when attempting to utilize a user's email address as part of a file path to upload an image to Firebase Storage. Code is here:
