TicTacToe how to reset containerView content? - ios

Question

I need some help over here. I try to learn... some things and practice but i'm not able to manage that function.
I have this function creating the container view:
func createGameView() {
let containerView = UIView()
containerView.frame = CGRect(x: 0,
y: self.screenHeight * 0.4,
width: screenWidth,
height: screenHeight * 0.6)
containerView.backgroundColor = UIColor(red:0.99, green:0.13, blue:0.00, alpha:1)
self.view.addSubview(containerView)
After that I have a function who will populate the container view with 9 squares
func createGridView( _ container : UIView) {
let buttonWidth = container.frame.size.width / 3
let buttonHeight = container.frame.size.height / 3
for i in [0,1,2] {
for j in 0...2 {
let button = UIButton(frame:
CGRect( x : buttonWidth * CGFloat (i),
y :buttonHeight * CGFloat (j),
width : buttonWidth,
height : buttonHeight ))
button.backgroundColor = UIColor.init(colorLiteralRed: 0.1, green: 0.89, blue: 0.05, alpha: 1)
button.layer.borderColor = UIColor.black.cgColor
button.layer.borderWidth = 1.0
container.addSubview(button)
button.addTarget(self, action: #selector(GameViewController.addGameValue(sender:)), for: .touchUpInside)
button.tag = i + 3 * j
self.gameButtons.append(button)
}
}
}
And I have a button called RESET
var resetButton = UIButton(frame:
CGRect(x: Double(containerView.frame.size.width - 100),
y: Double(containerView.frame.size.height - 60),
width: 60,
height: 40.0)
)
resetButton.setTitle ("Reset", for: UIControlState.normal)
resetButton.setTitleColor(UIColor.black, for: UIControlState.normal)
resetButton.setTitleColor(UIColor.white, for: .highlighted)
resetButton.layer.borderWidth = 1.0
resetButton.layer.borderColor = UIColor.black.cgColor
resetButton.layer.cornerRadius = 5.0
resetButton.addTarget(self, action: #selector(GameViewController.resetGame), for: UIControlEvents.touchUpInside)
containerView.addSubview(resetButton)
This is where i got a problem :(
func resetGame (sender: UIButton) {
// .addTarget(self, action: #selector(self.createGameView), for: .touchUpInside)
print(" reset me ")
// .addTarget(self, action: #selector(GameViewController.resetGame), for: .touchUpInside)
}
Anyone can tell me why none of those are not working to reset the value ? Is a tic tac toe game, and after put some x and 0 i want to restore the gridView to intial state. Got no ideea how to do it.

Answer 1

you already have all of the buttons that you need added to the view after createGridView is called, so on reset all you have to do is reset the button state, clear any scores/points and your ready to start again.
func resetGame() {
// reset any scores, colors etc
for button in self.gameButtons {
button.setTitle ("", for: UIControlState.normal)
button.backgroundColor = UIColor.init(colorLiteralRed: 0.1, green: 0.89, blue: 0.05, alpha: 1)
}
}
