如何获得相对于UIScreen的UITextField原点y位置？

// 获取UITextField相对于UIScreen的原点y位置
func getTextFieldOriginYRelativeToScreen(textField: UITextField) -> CGFloat {
    // 获取UITextField相对于其父视图的原点y位置
    let textFieldOriginY = textField.frame.origin.y
    
    // 获取UITextField所在父视图
    guard let superview = textField.superview else {
        return textFieldOriginY
    }
    
    // 将父视图的坐标系转换为UIScreen的坐标系
    let originYRelativeToScreen = superview.convert(CGPoint(x: 0, y: textFieldOriginY), to: UIScreen.main.coordinateSpace).y
    
    return originYRelativeToScreen
}
