Swift3 如何使用CosmicMinds材质库减少材质文本字段中动画占位符文本的空间？

我正在为我的一个项目使用CosmicMinds材料库。我面临一个悬停文本的问题。我想缩小我无法计算的空间

我的样本代码：

func prepareChangePasswordField() {
    enterPasswordText.placeholder = "Password"
    enterPasswordText.detailColor = Color.red
    enterPasswordText.delegate = self
    enterPasswordText.placeholderNormalColor = UIColor.lightGray
    enterPasswordText.placeholderActiveColor = Color.blue.base
    enterPasswordText.dividerNormalColor = Color.grey.base
    enterPasswordText.dividerActiveColor = Color.blue.base
    enterPasswordText.isVisibilityIconButtonEnabled = true
    enterPasswordText.visibilityIconButton?.tintColor = Color.grey.base.withAlphaComponent(passwordText.isSecureTextEntry ? 0.2 : 1.0)

}

func prepareConfirmPasswordField() {
    confirmPasswordText.placeholder = "Confirm password"
    confirmPasswordText.detailColor = Color.red
    confirmPasswordText.delegate = self
    confirmPasswordText.placeholderNormalColor = UIColor.lightGray
    confirmPasswordText.placeholderActiveColor = Color.blue.base
    confirmPasswordText.dividerNormalColor = Color.grey.base
    confirmPasswordText.dividerActiveColor = Color.blue.base
    confirmPasswordText.isVisibilityIconButtonEnabled = true
    confirmPasswordText.visibilityIconButton?.tintColor = Color.grey.base.withAlphaComponent(passwordText.isSecureTextEntry ? 0.2 : 1.0)

    //self.view.addSubview(userNameText)
    //view.layout(emailTextField).center(offsetY: -passwordField.height - 60).left(20).right(20)
}

您是否尝试过

placeholder VerticalOffset

属性？

textField.placeholder VerticalOffset=15

对我来说非常适合。
