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.

这是我的代码

推荐答案

您正在使用带字符串参数的函数进行调用，但是该函数不采用字符串参数. 通话应该是

You are calling the function with a string parameter, but the function does not take the string parameter. Either the call should be

presentWinningAlert()

不传递任何参数，否则函数应修改为

without passing any arguments or the function should be modified to

func presentWinningAlert(title: String){
moveCounter = 0
let alert = UIAlertController(title: title, message: "byr", preferredStyle: UIAlertControllerStyle.Alert)
