Question

我想做的是：

当用户点击＆＃34;忘记密码＆＃34;标签： 1- UIButton标题更改为＆＃34;发送＆＃34;

隐藏

2-密码文本字段

3 - 取消标签未隐藏

当用户点击取消时：显示1-密码文本字段

2- UIButton标题是＆＃34;登录＆＃34;

3-舞蹈是隐藏的

@IBAction func forgotTapped(_ sender: UITapGestureRecognizer) {

    if passwordtxt.isHidden == false {
        loginbtn.titleLabel?.text = "send"

    passwordtxt.isHidden = true
        forgotLab.isHidden = true
        top.constant = -50

        cancelLb.isHidden = false
    } else {
         if passwordtxt.isHidden == true  {
        forgotLab.isHidden = false

        if passwordtxt.isHidden == true {

            passwordtxt.isHidden = false
               loginbtn.titleLabel?.text = "login"
            cancelLb.isHidden = true
        }
    }

    }

}

@IBAction func cancelTapped(_ sender: Any) {

    cancelLb.isHidden = true
    forgotLab.isHidden = false
    loginbtn.titleLabel?.text = "send"

    if passwordtxt.isHidden == true {

        passwordtxt.isHidden = false

        top.constant = 50


}
}

问题：

现在一切都很好但是当我点击按钮时它会发送＆＃34;发送＆＃34;它改为＆＃34;登录＆＃34; !!它会回到它的黑色默认标题

无论如何都要让UIButton留下来＆＃34;发送＆＃34;即使点击它之后呢？

更新

  if passwordtxt.isHidden == false {
        loginbtn.setTitle("send", for: .normal)

    passwordtxt.isHidden = true
        forgotLab.isHidden = true
        top.constant = -50

        cancelLb.isHidden = false
    } else {
         if passwordtxt.isHidden == true  {
        forgotLab.isHidden = false

        if passwordtxt.isHidden == true {

            passwordtxt.isHidden = false
            loginbtn.setTitle("login", for: .normal)
            cancelLb.isHidden = true
        }
    }

    }

}

@IBAction func cancelTapped(_ sender: Any) {

    cancelLb.isHidden = true
    forgotLab.isHidden = false
    loginbtn.setTitle("send", for: .normal)

    if passwordtxt.isHidden == true {

        passwordtxt.isHidden = false

        top.constant = 50
}
}
