UIView基本动画

     // MARK: - UIView动画-淡入
     @IBAction func simpleAnimationFadeIn()
     {
         UIView.beginAnimations(nil, context: nil)
         UIView.setAnimationDuration(2.0)//设置动画时间
         testImageView.alpha = 0.0
         UIView.commitAnimations()

 //        //通过闭包实现 UIView淡入小狗
 //        UIView.animateWithDuration(0.3, animations: { () -> Void in
 //            self.testImageView.alpha = 0.0
 //        })
