ActionSheet to show Camera and Gallery to get the Image iOS Swift 3

-


First, you can create an image picker above viewDidLoad
        var Picker = UIImagePickerController() 

Before you must add the delegate to the ViewController

    class ViewController: UIViewController,UIAlertViewDelegate,UIImagePickerControllerDelegate

Then you can try the Below code
Code:
let alert:UIAlertController=UIAlertController(title: "Choose Image", message: nil, preferredStyle: UIAlertControllerStyle.actionSheet)

                let cameraAction = UIAlertAction(title: "Camera", style: UIAlertActionStyle.default)
                {
                    UIAlertAction in
                    
                    self.openCamera()
                }
                let galleryAction = UIAlertAction(title: "Gallery", style: UIAlertActionStyle.default)
                {
                    UIAlertAction in
                    self.openGallery()
                }
                let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.cancel)
                {
                    UIAlertAction in
                }
                Picker.delegate = self
                alert.addAction(cameraAction)
                alert.addAction(galleryAction)

                alert.addAction(cancelAction)
                //You must add this line then only in iPad it will not crash
                alert.popoverPresentationController?.sourceView = self.view
                self.present(alert, animated: true, completion: nil)
                default:
                break




Below are camera and gallery functions

        // MARK: - Photo Actions
        func openCamera()
        {
            if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.camera))
            {
                self.Picker.sourceType = UIImagePickerControllerSourceType.camera;
                self .present(self.Picker, animated: true, completion: nil)
                self.Picker.allowsEditing = false
                self.Picker.delegate = self
            }
        }
        
        func openGallery()
        {
            
            if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.savedPhotosAlbum){
                self.Picker.sourceType = UIImagePickerControllerSourceType.savedPhotosAlbum;
                self.Picker.allowsEditing = false
                self.Picker.delegate = self
                self.present(self.Picker, animated: true, completion: nil)
            }
        }


Below are after picking the image you can set the image to image view from camera or Gallery

        //    MARK: - Image Picker Delegate methods

        func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
            self.dismiss(animated: true, completion: nil)
        }
        
        func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
            self.ImageView.image = (info[UIImagePickerControllerOriginalImage] as? UIImage)
            self.dismiss(animated: true, completion: nil)
            
        }

Problem:  Invalid bundle. The “ UIInterfaceOrientationLandscap eLeft, UIInterfaceOrientationLandscap eRight, UIInterfaceOrientationPortrait ” orientations were provided for the UISupportedInterfaceOrientatio ns Info.plist key in the com.myapp bundle, but you need to include all of the “ UIInterfaceOrientationPortrait , UIInterfaceOrientationPortrait UpsideDown, UIInterfaceOrientationLandscap eLeft, UIInterfaceOrientationLandscap eRight” orientations to support iPad multitasking.
