Use of unresolved identifier 'requestIPViewController' , Ambiguous reference to member 'subscript'

Question

it shows me there are some problems on the code

So How Can I fix that?

self.presentViewController[requestIPViewController, animated:YES, completion:nil];

}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
    let image = info[UIImagePickerControllerOriginalImage] as UIImage

Answer 1

If it is in swift 2.3 then it should be like that

self.presentViewController(imagePicker, animated: true, completion: nil)

And you must type cast it like it

let image = info[UIImagePickerControllerOriginalImage]
            as! UIImage

And swift 3.0 it looks like that

self.present(imagePicker, animated: true, completion: nil)

And detegate method looks like that

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    let mediaType = info[UIImagePickerControllerMediaType] as! NSString

    self.dismiss(animated: true, completion: nil)

    if mediaType.isEqual(to: kUTTypeImage as String) {
        let image = info[UIImagePickerControllerOriginalImage]
            as! UIImage
    }
}

Hope it helps.
