アプリ開発を始めて，ついでにQiita初投稿．

TableViewのアクセサリーボタンにタグ付け成功．
1000の位はセクション，1の位はセルの行を表しています．

TestTableView.swift


class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {

    var _myTableView: UITableView!
    let SECTION_NAME = ["Clip", "History"]
    var _clipItemArray = ["iOS8", "iOS7", "iOS6", "iOS5", "iOS4"]
    var _historyItemArray = ["5.x", "4.x", "2.x", "1.x"]

//略

    // セルの内容
    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("MyCell", forIndexPath: indexPath) as UITableViewCell
        let button = UIButton(frame: CGRectMake(0, 0, BUTTON_SIZE, BUTTON_SIZE))
        button.setImage(UIImage(named: "Icon180.png"), forState: .Normal)
        button.addTarget(self, action: "tmpButtonTouch:", forControlEvents: UIControlEvents.TouchUpInside)
        button.tag = indexPath.section*1000+indexPath.row
        cell.accessoryView = button
        if indexPath.section == 0 {
            cell.textLabel!.text = "\(_recordItemArray[indexPath.row])"
        } else if indexPath.section == 1 {
            cell.textLabel!.text = "\(_historyItemArray[indexPath.row])"
        }
        return cell
    }

    func tmpButtonTouch(sender: UIButton!) {
        var button: UIButton = sender
        println("button.tag: \(button.tag)")
    }
