慕課網上學習了tableview的使用，突然讓我覺得iOS比android簡單多了，可能是我的感覺吧。因為android實現list view側拉刪除，動態移動item過程還是稍微有點復雜的。但是iOS卻只需要重寫幾個方法就可以實現了。我只能說iOS太神奇！我就跟著做了一下。

看效果，UI還可以。先上stZ喎?/kf/ware/vc/" target="_blank" class="keylink">vcnlib2FyZL3hubnNvKO6PGJyIC8+DQo8aW1nIGFsdD0="這裡寫圖片描述" src="/uploadfile/Collfiles/20150819/2015081908343584.png" title="\" />
navigate controller 實現一個導航欄。view controller 實現一個tableview,tableviewCell 。

            return todos.count
        }
    }

    // Row display. Implementers should *always* try to reuse cells by setting each cell's reuseIdentifier and querying for available reusable cells with dequeueReusableCellWithIdentifier:
    // Cell gets various attributes set automatically based on table (separators) and data source (accessory views, editing controls)
    //返回tableview的cell 就是list view的 item
    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{
        let cell = self.tableView.dequeueReusableCellWithIdentifier(todocell) as! UITableViewCell

        var title = cell.viewWithTag(103) as! UILabel
        var date = cell.viewWithTag(104) as! UILabel
        var image = cell.viewWithTag(102) as! UIImageView

        image.image = UIImage(named:todo!.image)
        title.text = todo!.title
        let locale = NSLocale.currentLocale()
        let dateFormat = NSDateFormatter.dateFormatFromTemplate(yyyy-MM-dd, options: 0, locale: locale)
        let dateFormatter = NSDateFormatter()
            dateFormatter.dateFormat = dateFormat
            date.text = dateFormatter.stringFromDate(todo!.date)
        return cell
    }

    //mark-UITableViewdelegate
    func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath){
        if editingStyle == UITableViewCellEditingStyle.Delete{
            todos.removeAtIndex(indexPath.row)
            self.tableView.deleteRowsAtIndexPaths([indexPath],withRowAnimation: UITableViewRowAnimation.Automatic)
        }
    }

    override func setEditing(editing: Bool, animated: Bool) {
        super.setEditing(editing, animated: animated)
        self.tableView.setEditing(editing, animated: animated)
    }
    //點擊確定按鈕 unsegue 操作 
    @IBAction func close(segue:UIStoryboardSegue){
        println(close)
        tableView.reloadData()
    }
    //實現側滑刪除，方法來自 UITableViewDelegate
    func tableView(tableView: UITableView, canMoveRowAtIndexPath indexPath: NSIndexPath) -> Bool{
        return editing
    }
   //實現cell移動，方法來自 UITableViewDelegate
    func tableView(tableView: UITableView, moveRowAtIndexPath sourceIndexPath: NSIndexPath, toIndexPath destinationIndexPath: NSIndexPath){
        let todo = todos.removeAtIndex(sourceIndexPath.row)
        todos.insert(todo, atIndex: destinationIndexPath.row)
    }
}

實現tableview 很明顯就是給一個Datasoure和一個delegate。view controller extension UITableViewDataSource(處理數據源),UITableViewDelegate （處理tableview各種操作）

最後記得綁定datasoure和delegate 。貌似是不是很簡單。我靠，android程序猿的路過點贊！！
