Swift简单列表

前端之家收集整理的这篇文章主要介绍了Swift简单列表前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

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
