UITextView的键盘出现时的滚动视图，但不是同一视图上的UITextField的滚动视图

import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var scrollView: UIScrollView!
    @IBOutlet weak var textView: UITextView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 监听键盘弹出通知
        NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(_:)), name: UIResponder.keyboardWillShowNotification, object: nil)
        
        // 监听键盘隐藏通知
        NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(_:)), name: UIResponder.keyboardWillHideNotification, object: nil)
    }
    
    @objc func keyboardWillShow(_ notification: Notification) {
        guard let userInfo = notification.userInfo,
              let keyboardFrame = userInfo[UIResponder.keyboardFrameEndUserInfoKey] as? CGRect else {
            return
        }
        
        // 获取键盘的高度
        let keyboardHeight = keyboardFrame.size.height
        
        // 设置UIScrollView的contentInset为键盘的高度
        scrollView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: keyboardHeight, right: 0)
    }
    
    @objc func keyboardWillHide(_ notification: Notification) {
        // 键盘隐藏时，将UIScrollView的contentInset重置为0
        scrollView.contentInset = .zero
    }
}
