ios - 如何更改 MDCTextField 占位符文本颜色？

Question

我目前正在使用它MDCTextInputControllerOutlined。我已经试过了

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！将 UIColor 设置inlinePlaceholderColor为MDCTextInputControllerOutlined

let emailTextField = MDCTextField()

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