Setting delegate for UIImagePicker returns error

Question

Having a problem in some swift code I had written for an OCR translation app. The code snippet is below:

@IBAction func btnOCR(sender: AnyObject) {

    var          


        

Answer 1

You must add UINavigationControllerDelegate to the class declaration.

class ViewController: UIViewController, UITextFieldDelegate, UIPickerViewDelegate, UIPickerViewDataSource, UIImagePickerControllerDelegate, UINavigationControllerDelegate {    


 // Some thing here

}

Answer 2

You forgot about UINavigationControllerDelegate in your ViewController class defenition.

The image picker’s delegate object.

Declaration

unowned(unsafe) var delegate: protocol<UIImagePickerControllerDelegate, UINavigationControllerDelegate>?
