UIImagePicker source type doesn't want to change

Question

I've set an UIImagePicker with a .savedPhotosAlbum as a sourcetype in order to develop an app.

import UIKit

class PictureViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    /////////////////// OUTLETS ////////////////////
    ///////////////// PROPERTIES ///////////////////
    var imagePicker = UIImagePickerController()

override func viewDidLoad() {
        super.viewDidLoad()

        imagePicker.delegate = self

    }

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        // Where do we want our photos from and we don't want edited photos
        imagePicker.allowsEditing = false
        imagePicker.sourceType = UIImagePickerControllerSourceType.camera
        imagePicker.cameraCaptureMode = .photo
        imagePicker.modalPresentationStyle = .fullScreen

        // Let's take the image from the picker
        let image = info[UIImagePickerControllerOriginalImage] as! UIImage
        snapImage.image = image

        // When the user picks a picture, disabling the background color of the UIImageView
        snapImage.backgroundColor = UIColor.clear

        // Closing the image picker
        imagePicker.dismiss(animated: true, completion: nil)
    }

    @IBAction func cameraTapped(_ sender: Any) {
        present(imagePicker, animated: true, completion: nil)
    }

Now that my app is finished I want to try my app on my Iphone so I changed this :

imagePicker.sourceType = .savedPhotosAlbum

to

imagePicker.sourceType = UIImagePickerControllerSourceType.camera

And I have added in my info.plist

<key>NSCameraUsageDescription</key>
    <string>We want to access your camera to ...</string>

But when I try to take a picture, it keeps showing me my photos album and that is the problem. I want to be able to take a picture from the camera of my phone.

Answer 1

You need to put this code

imagePicker.allowsEditing = false
imagePicker.sourceType = UIImagePickerControllerSourceType.camera
imagePicker.cameraCaptureMode = .photo
imagePicker.modalPresentationStyle = .fullScreen

in either viewDidLoad or cameraTapped

Problem - As right now you are putting this code in the delegate method of UIImagePicker which gets called after either picking the image or taking the image.
