《慕客网：IOS－动画入门》学习笔记

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 28 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  }
37 */ 38 39 }

前面都是大致的简单的入门步骤，不管是什么类型的动画的方法，比如下面的透明度变化动画：
