Swift 4 didFinishPickingMediaWithInfo save image - ios

Question

I am using UIImagePickerController to use my camera like so:
#objc func toggle() {
if UIImagePickerController.isSourceTypeAvailable(.camera) {
//Define UIImagePickerController variable
let imagePicker = UIImagePickerController()
//Assign the delegate
imagePicker.delegate = self
//Set image picker source type
imagePicker.sourceType = .camera
//Allow Photo Editing
imagePicker.allowsEditing = true
//Present camera
UIApplication.topViewController()?.present(imagePicker, animated: true, completion: nil)
}
}
Now I am trying to capture the image taken using the didFinishPickingMediaWithInfo method, I got this example online:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let imageUrl = info[UIImagePickerControllerOriginalImage] as! NSURL
let imageName = imageUrl.lastPathComponent
let documentDirectory = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first!
let photoURL = NSURL(fileURLWithPath: documentDirectory)
let localPath = photoURL.appendingPathComponent(imageName!)
let image = info[UIImagePickerControllerOriginalImage]as! UIImage
let data = UIImagePNGRepresentation(image)
do
{
try data?.write(to: localPath!, options: Data.WritingOptions.atomic)
}
catch
{
// Catch exception here and act accordingly
}
UIApplication.topViewController()?.dismiss(animated: true, completion: nil);
}
But I changed UIImagePickerControllerReferenceURL to UIImagePickerControllerOriginalImage as UIImagePickerControllerReferenceURL is nil. but after I change that I get this fatal error:
Could not cast value of type 'UIImage' (0x1b6b02b58) to 'NSURL'
How do I save the image take from the camera? What am I doing wrong?

Answer 1

Write your code as following this will give you image.
let image = info[UIImagePickerControllerOriginalImage] as! UIImage
UIImagePickerControllerOriginalImage return image not NSURL
Write following code to get image url in iOS 11. From iOS 11 UIImagePickerControllerImageURL is available, earlier there are UIImagePickerControllerMediaURL key to get image url.
if #available(iOS 11.0, *) {
if let imageURL = info[UIImagePickerControllerImageURL] as? URL {
print(imageURL)
}
} else {
if let imageUrl = info[UIImagePickerControllerMediaURL] as? URL {
print(imageUrl)
}
}
I hope this will help you.

The one who are searching for complete method to implement for Swift 4.2+
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let pickedImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage{
imageView.image = pickedImage
}
imgPicker.dismiss(animated: true, completion: nil)
}
This will return you the original image according to new syntax
For Image URL and Media URL, Use the respective
let imgURL = info[UIImagePickerController.InfoKey.imageURL]
let mediaURL = info[UIImagePickerController.InfoKey.mediaURL]
