How to disable keyboard appearing when hitting on a text field , iOS?

Question

I have a text field , and i need when the user presses it to show a custom picker.

The picker is shown fine , but the problem is that the keyboard appears on the bottom

Answer 1

swift 3.0 version

First set the delegate for the text field

self.textfield.delegate = self

Then in an extension

extension ViewController: UITextFieldDelegate {
    func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {
        return false
    }
}
