你可以这样做：

UIKeyboardAppearance currentAppearance = yourTextView.keyboardAppearance;
if (currentAppearance == UIKeyboardAppearanceDark) {
    // dark
}
else if (currentAppearance == UIKeyboardAppearanceDefault) {
    // default
}
else if (currentAppearance == UIKeyboardAppearanceLight) {
    // light
}

您可以使用输入视图，它与键盘样式相匹配。

let text = UITextView()
text.inputAccessoryView = UIInputView(frame: .init(x: 0, y: 0, width: 0, height: 40), inputViewStyle: .keyboard)
