如何修改文本字段，使光标不被覆盖？

Question

我正在尝试自定义我的UITextField。我已将拐角处的转弯并将情节提要中的textField边框设置为none。我对其进行了编码，以便在点击textField时，textField背景变为白色，边框变为灰色。但是，当我运行该应用程序时，textField边框会覆盖光标。

func textFieldDidBeginEditing(_ textField: UITextField) {
    // Change the background color for the textField and change the border width for the textField.
    textField.backgroundColor = UIColor.white
    textField.layer.borderWidth = 2
    textField.layer.borderColor = #colorLiteral(red: 0.9373082519, green: 0.9373301864, blue: 0.9373183846, alpha: 1)

    // Disable the doneButton while editing.
    doneButton.isEnabled = false
}

func textFieldDidEndEditing(_ textField: UITextField) {
    // Change the background color for the textField and change the border width for the textField.
    textField.backgroundColor = #colorLiteral(red: 0.9373082519, green: 0.9373301864, blue: 0.9373183846, alpha: 1)
    textField.layer.borderWidth = 0

    // Enable the doneButton when finished editing.
    doneButton.isEnabled = true

    // Set the title of the navigation bar to the text from the titleTextField.
    if titleTextField.text != "" {
        navigationItem.title = titleTextField.text
    }
}

当我想要填充时，我只对UITextField使用自定义类。
