Question

首先，我没有故事板，一切都是程序化的。我有三个TextFields，其中一个隐藏（isHidden = true）在登录按钮后面，登录按钮下面是一个注册按钮。如果点击注册按钮，登录按钮会在注册按钮下滑动，然后隐藏的textField将其isHidden属性设置为false。

我现在的问题是，当点击注册按钮时，登录按钮向下移动并显示文本字段但无法选择，当我尝试选择它时，登录按钮会快速回到原来的位置。

当键盘显示再次显示时，我的视图也会向上移动，我不认为这有帮助。

的TextField：

class SplitterTextField: UITextField, UITextFieldDelegate {

    var accessID: String!

    required init(frame: CGRect, accessID: String) {
        super.init(frame: frame)
        self.accessID = accessID
        setup()
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    private func setup() {
        delegate = self
        backgroundColor = Color.textFieldBackground
        accessibilityIdentifier = accessID
        textAlignment = .center
        returnKeyType = .done
        placeholder = NSLocalizedString("\(accessID!)PlaceHolder", comment: "")
    }

    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        resignFirstResponder()
        return true
    }
}

移动按钮功能：

@objc private func registerButtonTapped() {
    if confirmPasswordTextField.isHidden {
        animateLoginButton()
    } else {
        registerNewUser()
    }
}


@objc private func loginButtonTapped() {
    if !confirmPasswordTextField.isHidden {
        animateLoginButton()
    } else {
        //segue to next vc
    }
}

private func animateLoginButton() {
    if confirmPasswordTextField.isHidden {
        moveLoginButtonDown()
    } else {
        moveLoginButtonUp()
    }
}

private func moveLoginButtonDown() {
    //Move loginButton down revealing confirmationPasswordTextView behind it
    UIView.animate(withDuration: 0.3, animations: {
        self.loginButton.frame.origin.y += Layout.loginButtonYMovement
        self.confirmPasswordTextField.isHidden = false
    })
}

private func moveLoginButtonUp() {
    //Move the loginButton up, when it has finished moving hide the confirmationPasswordTextView
    UIView.animate(withDuration: 0.3, animations: {
        self.loginButton.frame.origin.y -= Layout.loginButtonYMovement
    }, completion: { _ in
        self.confirmPasswordTextField.isHidden = true
    })
}

查看控制器键盘功能：

func setupKeyboard() {
        NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(sender:)), name: NSNotification.Name.UIKeyboardWillShow,object: nil)
        NotificationCenter.default.addObserver(self,selector: #selector(keyboardWillHide(sender:)),name: NSNotification.Name.UIKeyboardWillHide,object: nil)

}

@objc private func keyboardWillShow(sender: NSNotification) {
    self.view.frame.origin.y = Layout.welcomeScreenKeyboardMovement
}

@objc private func keyboardWillHide(sender: NSNotification) {
    self.view.frame.origin.y = 0
}

任何建议都将不胜感激。谢谢，请告诉我是否需要更多上下文。所有视图都使用约束固定，并且不会发生涉及约束的错误。

按下注册按钮时添加这行代码。

var async = require('async')
var request = require('request')

async.waterfall([
  function(cb) {
    // send the first request
    request.post("https://example.com/first", function (err, resp) {
      // send the response to the next function or break in case there was an error
      cb(err, resp)
    })
  },
  function(resp, cb) {
    // check for the response
    if (resp.statusCode === 200) {
      // in case the response code is 200 continue to the next function
      return cb()
    }

    // if its not 200 break with the response code as an error
    return cb(resp.statusCode)
  },
  function(cb) {
    // send the verify
    request.get("https://example.com/statusCheck", function (err, resp, body) {
      // send the body of the response to the next function or break in case of an error
      cb(err, body)
    })
  }
], function (err, result) {
  // check if there was an error along the way
  if (err) {
    console.log("there was an error", err)
  } else {
    // all is good print the result
    console.log("result:", result)
  }
})

然后尝试选择该字段。正确设置框架按钮，使它们不会相互混淆。您可以打印按钮框以便更好地理解。

在isHidden设置为false
