新建Cocoa Touch Class，语言是swift

然后继续为界面添加一个普通的View Controller，并且添加前面视图的静态table的转向剪头指向这个View Controller，然后在这个视图上添加普通的UIView

 1 class PositionViewController: UIViewController {
 2 
 3     //2 添加 UIView组件 的链接
 4     @IBOutlet weak var redSquare: UIView!
 5     
 6     override func viewDidLoad() {
 7         super.viewDidLoad()
 8 
 9         // Do any additional setup after loading the view.
10     }
11 
12     override func didReceiveMemoryWarning() {
13         super.didReceiveMemoryWarning()
14         // Dispose of any resources that can be recreated.
15     }
16     //1
17     override func viewDidAppear(animated: Bool) {
18         //这个方法被执行的时间在生命周期中比较合适
19         UIView.animateWithDuration(1, animations: {
20             self.redSquare.center.x = self.view.bounds.width - self.redSquare.center.x
21         })
22         UIView.animateWithDuration(1, delay: 2, options: nil, animations: {
23             self.redSquare.center.x = self.view.bounds.width - self.redSquare.center.x
24             self.redSquare.center.y = self.view.bounds.height - self.redSquare.center.y
25         }, completion: nil)
26     }
27

29     /*
30     // MARK: - Navigation
31 
32     // In a storyboard-based application, you will often want to do a little preparation before navigation
33     override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
34         // Get the new view controller using segue.destinationViewController.
35         // Pass the selected object to the new view controller.
36     }
