如果您将发件人类型设置为 UIButton，那么在您的按钮操作中，所有 if 条件都是不必要的，因此您可以直接访问 currentTitle property of UIButton. Also instead of trying to get textField from stackView you can make IBOutletCollection of UITextField, if you don't know how to male IBOutletCollection you can follow this medium documentation。创建一个字符串变量来存储 OTP 并使用它来赋值给 textField

@IBOutlet var otpFields: [UITextField]! //Make sure you add textFields in proper order
var otpString = "" // to assign value to textField.

现在添加一种方法来设置从 otpString 到 textFields 的文本，并像下面这样更改您的按钮操作。

func setupOTPFields() {
    for (index,ch) in otpString.enumerated() {
        otpFields[index].text = String(ch)
    }
}

//action of 0-9 button
@IBAction func one(_ sender: UIButton) {
    if otpString.count <= 6 { //Because you only have 6 character otp
        otpString += (sender.currentTitle ?? "")
        //Call setup field method
        self.setupOTPFields()
    }
}

//action of c button
@IBAction func cButtonClick(_ sender: UIButton) {
    if !otpString.isEmpty {
        otpString = String(otpString.dropLast())
        //Call setup field method
        self.setupOTPFields()
    }
}
