arrays - Swift 数组索引超出范围

Question

为什么这不起作用？

var lottoTaulukko = [Int]()
var finalLottoTaulukko = [[Int]]()

var laskuri1 = 0
var laskuri2 = 0

while laskuri2 < Int(riviLaskuri) {

    while laskuri1 < Int(lottoMuoto) {
        showRowsLabel.stringValue += "\(lottoTaulukko[laskuri1])"
        finalLottoTaulukko[laskuri2][laskuri1] = lottoTaulukko[laskuri1] // ERROR IS HERE IN THIS LINE! fatal error: Index out of range

showRowsLabel.stringValue += " "
        laskuri1 += 1
    }

    laskuri1 = 1
    showRowsLabel.stringValue += "\n"
    if laskuri2==10 {showRowsLabel.stringValue += "\n"}
    lottoTaulukko.shuffle()
    laskuri2 += 1
}

同样指定数组大小:

let size = ARRAY.count

看看它是否适合您!
