I am attempting to make a TicTacToe game. I'm trying to use this checkForWinner function but keep getting errors. Any help is greatly appreciated.
Here's my code
class ViewController: UIViewController { @IBOutlet weak var CurrentLetterLabel: UILabel!@IBOutlet weak var label1: UILabel!@IBOutlet weak var label2: UILabel!@IBOutlet weak var label3: UILabel!@IBOutlet weak var label4: UILabel!@IBOutlet weak var label5: UILabel!@IBOutlet weak var label6: UILabel!@IBOutlet weak var label7: UILabel!@IBOutlet weak var label8: UILabel!@IBOutlet weak var label9: UILabel!@IBOutlet weak var label10: UILabel!@IBOutlet weak var label11: UILabel!let letter = "XOXOXOXOXO"var moveCounter = 0var currentLetter:Character!var labelArray = [UILabel]()override func viewDidLoad() {super.viewDidLoad()labelArray.append(label1)labelArray.append(label2)labelArray.append(label3)labelArray.append(label4)labelArray.append(label5)labelArray.append(label6)labelArray.append(label7)labelArray.append(label8)labelArray.append(label9)labelArray.append(label10)labelArray.append(label11)getCharacter()}func getCharacter(){let myRange = Range<String.Index>(start: letter.startIndex.advancedBy(moveCounter), end: letter.startIndex.advancedBy(moveCounter + 1))CurrentLetterLabel.text = letter.substringWithRange(myRange)currentLetter = Character(letter.substringWithRange(myRange))}func clearLabels(Action:UIAlertAction){label1.text = ""label2.text = ""label3.text = ""label4.text = ""label5.text = ""label6.text = ""label7.text = ""label9.text = ""label10.text = ""label11.text = ""}func presentWinningAlert(){moveCounter = 0let alert = UIAlertController(title: "", message: "byr", preferredStyle: UIAlertControllerStyle.Alert)let okAction = UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: clearLabels)alert.addAction(okAction)presentViewController(alert, animated: true, completion: nil) }@IBAction func onTapped(sender: UITapGestureRecognizer) {print("Here")let selectedPoint = sender.locationInView(self.view)print(selectedPoint)for label in labelArray{if CGRectContainsPoint(label1.frame, selectedPoint){label1.text = String(currentLetter)}if CGRectContainsPoint(label2.frame, selectedPoint){label2.text = String(currentLetter)}if CGRectContainsPoint(label3.frame, selectedPoint){label3.text = String(currentLetter)}if CGRectContainsPoint(label4.frame, selectedPoint){label4.text = String(currentLetter)}if CGRectContainsPoint(label5.frame, selectedPoint){label5.text = String(currentLetter)}if CGRectContainsPoint(label6.frame, selectedPoint){label6.text = String(currentLetter)}if CGRectContainsPoint(label7.frame, selectedPoint){label7.text = String(currentLetter)}if CGRectContainsPoint(label8.frame, selectedPoint){label8.text = String(currentLetter)}if CGRectContainsPoint(label9.frame, selectedPoint){label9.text = String(currentLetter)}if CGRectContainsPoint(label10.frame, selectedPoint){label10.text = String(currentLetter)}}moveCounter++if moveCounter == 9{presentWinningAlert()}getCharacter()}func checkForWinner(){if label1.text == label2.text && label2.text == label3.text && label3.text != "" {presentWinningAlert("\(label3.text!)")}else if label4.text == label5.text && label5.text == label6.text && label6.text != "" {presentWinningAlert("\(label6.text!)") }else if label7.text == label8.text && label8.text == label9.text && label9.text != "" {presentWinningAlert("\(label9.text!)")} else if label1.text == label4.text && label4.text == label7.text && label7.text != "" {presentWinningAlert("\(label7.text!)")}else if label2.text == label5.text && label5.text == label8.text && label8.text != "" {presentWinningAlert("\(label8.text!)")}else if label3.text == label6.text && label6.text == label9.text && label9.text != "" {presentWinningAlert("\(label9.text!)")}else if label1.text == label5.text && label5.text == label9.text && label9.text != "" {presentWinningAlert("\(label9.text!)")}else if label3.text == label5.text && label5.text == label7.text && label7.text != "" {presentWinningAlert("\(label7.text!)")}if moveCounter == 9 {presentWinningAlert("No One")}}}Best Answer
You are calling the function with a string parameter, but the function does not take the string parameter. Either the call should be
presentWinningAlert()without passing any arguments or the function should be modified to
func presentWinningAlert(title: String){moveCounter = 0let alert = UIAlertController(title: title, message: "byr", preferredStyle: UIAlertControllerStyle.Alert)The compiler's message is misleading, and other languages would give a better message instead, something like:
Parameter type mismatch. Can not implicitly convert X to Y.How to reproduce:
let myVariable: Int32 = 100;let size = CGSize(width: myVariable, height: myVariable);How to fix:
let myVariable: Int32 = 100;let size = CGSize(width: CGFloat(myVariable), height: CGFloat(myVariable));
