Catch photo upload in WKWebview

Question

I would like to intercept photo uploading which was started from javascript from site loaded with WKWebview. Normally I would implement:

`func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {`

but since photo uploading does not comes from me I am not able to set delegate.

I had one try with overriding UIImagePickerController and setting delegate in viewDidLoad but it seems to not working at all.

Answer 1

It's possible:

extension UIImagePickerController {

     open override func viewDidLoad() {
        super.viewDidLoad()
        self.delegate = picker
     }
}

where picker has to implement UIImagePickerControllerDelegate
