在使用UICollectionViewFlowLayout时，如何在键盘存在的情况下移动视图以查看UITextField

// 监听键盘弹出和隐藏事件
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(_:)), name: UIResponder.keyboardWillShowNotification, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(_:)), name: UIResponder.keyboardWillHideNotification, object: nil)

// 键盘弹出时的处理方法
@objc func keyboardWillShow(_ notification: Notification) {
    guard let keyboardFrame = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? CGRect else {
        return
    }
    
    // 计算需要移动的距离
    let textFieldFrame = textField.convert(textField.bounds, to: view)
    let distanceToMove = textFieldFrame.maxY - keyboardFrame.minY + 10 // 加上一定的额外空间
    
    // 调整UICollectionView的contentInset和contentOffset
    collectionView.contentInset.bottom = distanceToMove
    collectionView.contentOffset.y += distanceToMove
}

// 键盘隐藏时的处理方法
@objc func keyboardWillHide(_ notification: Notification) {
    // 还原UICollectionView的contentInset和contentOffset
    collectionView.contentInset = .zero
    collectionView.contentOffset.y = 0
}
