ios - 如何更改 MDCTextField 占位符文本颜色？

Question

我目前正在将其与 MDCTextInputControllerOutlined 一起使用。我已经尝试过了

self.emailTextField.attributedPlaceholder = NSAttributedString(string: "Email", attributes: [.font: UIFont.ralewayFont(ofSize: 18.0, weight: .semibold), .foregroundColor: UIColor.white])

但不工作

找到了!为 MDCTextInputControllerOutlined

将 UIColor 设置为 inlinePlaceholderColor

let emailTextField = MDCTextField()

let emailTextFieldController = MDCTextInputControllerOutlined(textInput: emailTextField)
emailTextFieldController.inlinePlaceholderColor = .white
