sb上先加入NavigationController ,拖拽TABLEVIEW上去，上面再放入Navigation Item （里面放入Bar Button Item）。
注意新建立了一个
UITableViewController的类绑定到TABLEVIEW
点击某行，进入新界面：
tododetail
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
NSLog("click is:\(indexPath.row)")
var viewController = self.storyboard?.instantiateViewControllerWithIdentifier("tododetail") as!ViewController
rowIndex = indexPath.row
self.navigationController?.pushViewController(viewController, animated: true)
}
明细页面，LABLE的OUTLET是使用CTROL拖拽法自己生成的
var rowIndex = 0;
override func
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
labe1.text = "Row index is:\(rowIndex)"
}
@IBOutlet weak var labe1: UILabel!
