键盘出现时无法上移自定义UIView

NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(_:)), name: UIResponder.keyboardWillShowNotification, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(_:)), name: UIResponder.keyboardWillHideNotification, object: nil)

@objc func keyboardWillShow(_ notification: Notification) {
    if let keyboardSize = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
        // 计算键盘高度
        let keyboardHeight = keyboardSize.height
        
        // 调整UIView的位置，使其上移键盘高度的距离
        // 例如，如果UIView是一个UITextField，可以将其的底部Y坐标减去键盘高度
        yourCustomView.frame.origin.y -= keyboardHeight
    }
}

@objc func keyboardWillHide(_ notification: Notification) {
    // 恢复UIView的位置，使其回到原始位置
    yourCustomView.frame.origin.y = originalYPosition
}
