这篇博客介绍了如何在Swift中获取UITableView实例，并实现数据源和代理方法，以展示列表内容。

得到一个UITableView实例: @IBOutlet var showHomeTBView: UITableView?

同样的实现其数据源方法和代理方法:

    // MARK: - UITableViewDataSource UITableViewDelegate
    
    func numberOfSections(in tableView: UITableView) -> Int {
        
        return 1
    }
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        
        return self.itemsArray!.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        
        var showHomeTableViewCell: ShowHomeTableViewCell!
        showHomeTableViewCell = self.showHomeTBView!.dequeueReusableCell(withIdentifier: "ShowHomeTableViewCellIdentifier", for: indexPath) as? ShowHomeTableViewCell
        showHomeTableViewCell!.showImageView!.image = UIImage(named: "ball-Image")
        showHomeTableViewCell?.showNameLabel?.text = self.itemsArray![indexPath.row] as? String
        showHomeTableViewCell.delegate = self
        
        return showHomeTableViewCell
    }
    
    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        
        return 160
    }
    
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        
        self.selectedIndexPath = indexPath
        
        //self.performSegue(withIdentifier: "gotoDetailViewController", sender: self)
        
        self.showHomeTBView?.deselectRow(at: indexPath, animated: true)
    }
    
    // MARK: - TableViewCell delegate
    
    func doSelect(_ sender: Any) {
        
        /*
        UIView *view = [button superview];
        GameForPlaceTableViewCell *gameForPlaceTableViewCell = (GameForPlaceTableViewCell *)[view superview];
        NSIndexPath *indexPath = [self.gameForPlaceTBView indexPathForCell:gameForPlaceTableViewCell];
        self.selectedIndexPath = indexPath;
        */
        
        let view = (sender as! UIButton).superview
        let showHomeTableViewCell = view!.superview as! ShowHomeTableViewCell
        let indexPath = self.showHomeTBView!.indexPath(for: showHomeTableViewCell)
        self.selectedIndexPath = indexPath
        
        self.performSegue(withIdentifier: "gotoDetailViewController", sender: self)
    }

自定义UITableViewCell:

class ShowHomeTableViewCell: UITableViewCell {
    
    @IBOutlet var showImageView: UIImageView?
    @IBOutlet var showNameLabel: UILabel?
    @IBOutlet var selectButton: UIButton?
    var delegate: ShowHomeTableViewCellDelegate?

    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
        
        self.selectButton!.layer.cornerRadius = 15
        self.selectButton!.layer.masksToBounds = true
        self.selectButton!.backgroundColor = UIColor.blue
    }

    override func setSelected(_ selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }

    @IBAction func doSelect(_ sender: Any) {
        
        if delegate != nil {
            delegate!.doSelect(sender)
        }
    }
}

点击自定义的UITableViewCell上得button时用代理传递：

protocol ShowHomeTableViewCellDelegate {
    
    func doSelect(_ sender: Any)
}

实现vc的跳转:

    // MARK: - Transmit data
    
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        
        let detailVC = segue.destination as! DetailViewController
        if segue.identifier == "gotoDetailViewController" {
            detailVC.nameStr = self.itemsArray![self.selectedIndexPath!.row] as? String
        }
    }

效果
