How to make UIImagePickerController for camera and photo library at the same time in swift

Question

I use UIImagePickerController to take a photo by camera of iPhone.

I want to show both "take a photo" and "choose a photo".

My code

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

I tried to use imagePicker.sourceType = .Camera and imagePicker.sourceType = .PhotoLibrary together to do this, but it doesn't work...

Thank you

Import UIImagePickerControllerDelegate and create a variable to assign UIImagePickerController var imagePicker = UIImagePickerController() and set imagePicker.delegate = self.

Create an action sheet to display options for 'Camera' and 'Photo library'.

On your button click action:

@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(UIImagePickerController.SourceType.camera))
        {
            imagePicker.sourceType = UIImagePickerController.SourceType.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 = UIImagePickerController.SourceType.photoLibrary
        imagePicker.allowsEditing = true
        self.present(imagePicker, animated: true, completion: nil)
    }

Swift 5 +:

Action sheet with camera and gallery:

//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)
    }

Camera image picker functionality:

func openCamera()
{
    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)
    }
    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)
    }
}

Gallery image picker functionality:

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

ImagePicker delegate:

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

Answer 3

set delegate like:

UIImagePickerControllerDelegate,UINavigationControllerDelegate

take one imageview so we can display selected/captured image:

@IBOutlet weak var imageViewPic: UIImageView!

For capture new image by using device camera:

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)
    }

For select photo from gallery:

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)
    }

This is the delegate method :

     //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)
}

set permission for access camera and photo in info.plist like:

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

Create view controller and add button and image in the storyboard

add UIImagePickerControllerDelegate,UINavigationControllerDelegate protocols in view controller

camera action button enter following code

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)

Add following function in view controller

 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)
    }
}

in info.plist add row with

 Privacy - Photo Library Usage Description
Privacy - Camera Usage Description
