Resign First Responder function in SKScene - xcode

Question

I am trying to create a game that requires to create a textfield in SKScene. I have built the text field successfully, but bringing the keyboard down is the problem. This is my code so far.
import SpriteKit
import GameplayKit
import UIKit
class GameScene: SKScene {
var sceneFrame : CGRect = CGRect()
var textFieldFrame : CGRect = CGRect()
var textField : UITextField = UITextField()
var skView: SKView = SKView()
override func didMove(to view: SKView) {
sceneFrame = CGRect(origin: .zero, size: CGSize(width: 200, height: 200))
let scene = SKScene(size: sceneFrame.size)
scene.backgroundColor = UIColor.lightGray
textFieldFrame = CGRect(origin: .init(x: 100, y: 200), size: CGSize(width: 200, height: 30))
textField = UITextField(frame: textFieldFrame)
textField.backgroundColor = UIColor.white
textField.placeholder = "Phone Number"
textField.keyboardType = .numberPad
textField.resignFirstResponder()
self.view!.addSubview(textField)
self.view!.presentScene(scene)
// Where to put the textField.resignFirstResponder() ?
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
}
override func update(_ currentTime: TimeInterval) {
// Called before each frame is rendered
}
}
Any answers would be helpful.

Answer 1

The problem is you are not adding:
textfield.delegate = self
Then you could call the function:
func textFieldShouldReturn(textField: UITextField) -> Bool {
// Hides the keyboard
textField.resignFirstResponder()
return true
}
Declaring the delegate statement initiate the function textFieldShouldReturn.
Hope this helps :)
