tap是指轻触手势。类似鼠标操作的点击。从iOS 3.2版本开始支持完善的手势api：
tap：轻触
long press：在一点上长按
pinch：两个指头捏或者放的操作
pan：手指的拖动
swipe：手指在屏幕上很快的滑动
rotation：手指反向操作
这为开发者编写手势识别操作，提供了很大的方便，想想之前用android写手势滑动的代码（编写android简单的手势切换视图示例），尤其感到幸福。
这里写一个简单的tap操作。在下面视图的蓝色视图内增加对tap的识别：
当用手指tap蓝色视图的时候，打印日志输出：
代码很简单，首先要声明t ...
使用手指動態來切換UIView，意思就是說當手指頭接觸螢幕然後橫向或是縱向劃過螢幕後，就可以切換不同的畫面。關於手指動態偵測的API，主要是UIGestureRecognizer，他衍生的subclass包含，UITapGestureRecognizerUIPinchGestureRecognizerUIRotationGestureRecognizerUISwipeGestureRecognizerUIPanGestureRecognizerUILongPressGestureRecognizer以UISwipeGestureRecognizer為例，若要讓UIView具備手指動態的偵測，必須 ...

You change the default animation timing by setting the current animation context’s duration like this:
[NSAnimationContext beginGrouping];
[[NSAnimationContext currentContext] setDuration:2.0f];
// your code here

注意
The NSAnimationContext duration affects ...

Smooth Moves
you first ask mover for its animator, and you then send setFrame: to that instead.

}
