ios - Int 在 UILabel 中没有达到 11

Question

我有一个 nihoshim UILabel，他的最后一个字符是 0，每次 else 语句为真并调用时，我都想更新它，一切正常，直到它达到 10，然后它突然等于 1，

 guard var yoo = Int(nihoshim.text!.suffix(1)) else {
        return
    }
    var alephbet = ["א","ב","ג","ד","ה","ו","ז","ח","ט","י","כ","ל","מ","נ","ס","ע","פ","צ","ק","ר","ש","ת"]
    nihoshim.text! = "ניחושים: " + String(yoo)
    if gameLabel.text!.count <= 3 && (sender.tag == 18 || sender.tag == 20) {
        gameLabel.text = gameLabel.text! + alephbet[alpha.index(after: tag) - 1]
        sender.isHidden = true
    } else if sender.tag == 10 && !(gameLabel.text?.contains("יי"))!{

        sender.isHidden = false
        gameLabel.text = gameLabel.text! + alephbet[alpha.index(after: tag) - 1]
    }
    else {
        yoo += 1
        nihoshim.text! = "ניחושים: " + String(yoo)
        sender.isHidden = true
        print(yoo)
    }

当我打印它时，即使是 yoo 的值也无缘无故地变为 0。当我将它更新为 yoo += 20 我点击它几次，它仍然是 20，再点击一次它变为 1。

问题是您只检查最后一个字符，您需要在字符串末尾获取整数，例如:

let numberString = nihoshim.text!.split(separator: " ").last ?? nihoshim.text!.suffix(0)

在你的代码中它看起来像这样:

let numberString = nihoshim.text!.split(separator: " ").last ?? nihoshim.text!.suffix(0)
guard var yoo = Int(numberString) else {
    return
}
var alephbet = ["א","ב","ג","ד","ה","ו","ז","ח","ט","י","כ","ל","מ","נ","ס","ע","פ","צ","ק","ר","ש","ת"]
nihoshim.text! = "ניחושים: " + String(yoo)
if gameLabel.text!.count <= 3 && (sender.tag == 18 || sender.tag == 20) {
    gameLabel.text = gameLabel.text! + alephbet[alpha.index(after: tag) - 1]
    sender.isHidden = true
} else if sender.tag == 10 && !(gameLabel.text?.contains("יי"))!{

    sender.isHidden = false
    gameLabel.text = gameLabel.text! + alephbet[alpha.index(after: tag) - 1]
}
else {
    yoo += 1
    nihoshim.text! = "ניחושים: " + String(yoo)
    sender.isHidden = true
    print(yoo)
}
