Question

I am working in iPhone messaging based app.

I want to show keyboard with keyboard inputAccessoryView in keyboard without using UITextView and

Answer 1

Make a View, Label or what ever to conform to UIKeyInput. In this case a UIView

Sub class a UIView:

import UIKit

class KeyInputView: UIView {
   var _inputView: UIView?

   override var canBecomeFirstResponder: Bool { return true }
   override var canResignFirstResponder: Bool { return true }

   override var inputView: UIView? {
       set { _inputView = newValue }
       get { return _inputView }
   }
}

// MARK: - UIKeyInput
//Modify if need more functionality
extension KeyInputView: UIKeyInput {
    var hasText: Bool { return false }
    func insertText(_ text: String) {}
    func deleteBackward() {}
}

Setup your View, in this case with a picker (in viewDidLoad or where ever)

let languangePicker = UIPickerView()
languangePicker.dataSource = self
languangePicker.delegate = self
keyInputView.inputView = languangePicker

To show:

keyInputView.becomeFirstResponder()

To hide:

keyInputView.resignFirstResponder()

Set picker data, from datasource (compiler force u to do it)

Grab data picker events from delegate
