Swift中TableView的根本使用

Xcode6新建一个项目，采用swift创建代码

创建一个ViewController继承UITableViewController

涉及了模型，控制器

模型：ZLPlace.swift

class ZLPlace: NSObject {
    var place = ""
    var visited = false
}

tableViewController 控制器

import UIKit

class ViewController: UITableViewController {
    
    // 静态数据数组，存放模型
    var arrs = [ZLPlace]()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let place2 = ZLPlace()
        place2.place = "zhang2"
        arrs.append(place2)
        
        let place3 = ZLPlace()
        place3.place = "zhang3"
        arrs.append(place3)
        
        let place4 = ZLPlace()
        place4.place = "zhang1"
        arrs.append(place4)
        
        self.tableView.reloadData()
    }
    
    // 数据源方法, 返回多少组
    override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1;
    }
    
    // 每组有多少行
    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return arrs.count;
    }
    
    // 每行展示什么内容
    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as UITableViewCell
        
        let place = arrs[indexPath.row]
        
        cell.textLabel.text = place.place
        
        return cell;
        
    }
    
    // 点击每个cell触发什么事件
    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        
        let place = arrs[indexPath.row]
        place.visited = !place.visited;
        
        let cell = tableView.cellForRowAtIndexPath(indexPath)
        cell?.backgroundColor = UIColor.clearColor()
        if(place.visited){
            cell?.accessoryType = UITableViewCellAccessoryType.Checkmark
        }else{
            cell?.accessoryType = UITableViewCellAccessoryType.None
        }
    }
    
    // 点击编辑按钮
    @IBAction func editing(sender: AnyObject) {
        self.tableView.setEditing(true, animated: true)
    }
    
    // 删除每个cell
    override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
        if editingStyle == UITableViewCellEditingStyle.Delete{
            arrs.removeAtIndex(indexPath.row)
            tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Top)
        }
    }
    
}
