按下按钮后向上打开表格视图很热？

问题描述

有没有办法在快速按下按钮后向上而不是向下打开我的表格视图？

当我按下按钮并打开TableViewControler时，下面没有足够的空间来显示tableview中所有可能的选项，因此，我想知道有没有办法向上打开tableview？

附上问题的截图如下：screenshot

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
    }
    
    override func viewDidLoad() {
        
        overrideUserInterfaceStyle = .light

        super.viewDidLoad()
        tableView.delegate = self
        tableView.dataSource = self
        tableView.register(CellClass.self,forCellReuseIdentifier: "Cell")
    }
    
    
    //MARK: What happens when you click "When"
    
    func addTransparentView(frames: CGRect) {
        let window = UIApplication.shared.keyWindow
        transparentView.frame = window?.frame ?? self.view.frame
        self.view.addSubview(transparentView)
        
        tableView.frame = CGRect(x: frames.origin.x,y: frames.origin.y + frames.height,width: frames.width,height: 0)
        self.view.addSubview(tableView)
        tableView.layer.cornerRadius = 15
        
        
        transparentView.backgroundColor = UIColor.black.withAlphaComponent(0.9)
        tableView.reloadData()
        let tapgesture = UITapGestureRecognizer(target: self,action: #selector(removeTransparentView))
        transparentView.addGestureRecognizer(tapgesture)
        transparentView.alpha = 0
        UIView.animate(withDuration: 0.4,delay: 0.0,usingSpringWithdamping: 1.0,initialSpringVeLocity: 1.0,options: .curveEaseInOut,animations: {
            self.transparentView.alpha = 0.5
            self.tableView.frame = CGRect(x: frames.origin.x,y: frames.origin.y + frames.height + 5,height: CGFloat(self.dataSource.count * 50))
        },completion: nil)
    }
    
    @objc func removeTransparentView() {
        let frames = selectedButton.frame
        UIView.animate(withDuration: 0.4,animations: {
            self.transparentView.alpha = 0
            self.tableView.frame = CGRect(x: frames.origin.x,height: 0)
        },completion: nil)
    }   


         @IBAction func selectTimeButtonpressed(_ sender: Any) {
        dataSource = ["Now ?","THIS EVENING ?","ANYTIME TODAY ?","IN A FEW HOURS ⏳","SOMETIME TOMORROW ✨","TOMORROW EVENING ?","OVER THE WEEKEND ?"]
        selectedButton = selectTimeButton
        addTransparentView(frames: selectTimeButton.frame)
        timeDetails = selectedButton.titleLabel?.text ?? "nothing is here in timedetails"
        print(timeDetails,"from selectTImeBUttonpressed")

    }


    extension WhatDoYouWannaDoViewController   {
    func tableView(_ tableView: UITableView,numberOfRowsInSection section: Int) -> Int {
        return dataSource.count
    }
    
    func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell",for: indexPath)
        cell.textLabel?.text = dataSource[indexPath.row]
        cell.backgroundColor = .white
        cell.textLabel?.font = UIFont(name: "ContrailOne-Regular",size: 20)!

        return cell
    }
    
    func tableView(_ tableView: UITableView,heightForRowAt indexPath: IndexPath) -> CGFloat {
        return 50
    }
    
    func tableView(_ tableView: UITableView,didSelectRowAt indexPath: IndexPath) {
        selectedButton.setTitle(dataSource[indexPath.row],for: .normal)
        removeTransparentView()
    }
}
