问题
Hi I am new to pdfkit and iOS applications, I want to take a picture with device and then convert the image to pdf. taking pictures with camera and saving it on Camera Roll works completely fine, the problem is when I want to create pdf from that image it needs the name of the image, how I can find it?
and another question is it possible to implement any pdf editor with pdfkit to edit image?
Appreciate any help. below is my imagePickerController codes.
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage
if (Mylibrary)
{
}
else
{
UIImageWriteToSavedPhotosAlbum(pickedImage!, nil, nil, nil);
let image = UIImage(named: "????") //the problem is here
let newPage = PDFPage(image: image!)
}
picker.dismiss(animated: true, completion: nil)
}

There's no need to instantiate a new image since the image is already stored in the pickedImage variable. You just need to initialize the new PDFPage object with pickedImage. Use ImageKit to edit the image before using it to initialize a new PDFPage object.
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
guard let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage else { return }
// Adds pickedImage to the user’s Camera Roll album.
UIImageWriteToSavedPhotosAlbum(pickedImage, nil, nil, nil)
// Creates a new PDFPage object and initializes it with pickedImage.
let newPage = PDFPage(image: pickedImage)
dismiss(animated: true, completion: nil)
}
