UIVIEW　动画接口解释

//------------时间长短------------

//------------速度的变化------------
//		UIViewAnimationCurveEaseInOut,         // slow at beginning and end

//		UIViewAnimationCurveEaseOut,           // slow at end
//		UIViewAnimationCurveLinear

//------------延迟------------

//------------执行一段时间的动画　后面是直接显示------------

//------------线程中的动画------------
