Question

我有一个nihoshim UILabel，他的最后一个字符为0，并且我想在else语句为真并被调用时每次更新一次，一切正常，直到达到10，然后突然等于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yoo的值也毫无理由地变为0。当我将其更新为yoo += 20时，我单击了几次，仍然点击了20次又单击了1次。

问题是您只检查最后一个字符，需要在字符串末尾获取整数，例如：

Nb

在您的代码中，它看起来像这样：

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

UILabel中的Int未达到11
