//数据定义部分
//定义行数和列数
let rows = 9
let cols = 5
//定义干扰项数量
let distractorMount = 5
//定义不同项数量
let differentMount = 3
//定义上下两个图形数组
var iv1 : Array<Strig> = []
var iv2 : Array<Strig> = []
//定义上下相同的干扰项数组
var cords : Array<(Int,Int)> = []
//定义上下不同的数组
var errorCords : Array<(Int,Int)> = []
//干扰项和不同项只能是B,^,v,>,<
let images : Array<Strig> = ["B","^","V",">","<"]
//数据定义结束

//函数1：初始化图形
func initGame() {
    iv1.removeAll()
    iv2.removeAll()
    for _ in 0..<rows {

            iv1.append("a")
            iv2.append("a")
        }
    }

//函数2：显示
func display(){
    print("up image begin-----")
    for i in 0..<rows {
        for j in 0..<cols {

        let row =Int (arc4random () )% rows

        errorCords.append ((row, col))
        /从images提供的宇符中选择一
        let index=Int (arc4random () ) % images.count
        /选择上面因形，还是下面图形？
        let which=Int (arc4random () ) %2
        //影响 iv1 和iv2这两个图形
        if which == 0{
            iv1 [cols*row+col] =images [index]

        else{
