cc.director.getVisibleSize();//获取运行场景的可见大小
cc.director.getWinSize();//获取视图的大小，以点为单位
cc.director.getWinSizeInPixels();//获取视图大小，以像素为单位
cc.view.getFrameSize();//Returns the frame size of the view
cc.view.getViewPortRect();//Returns the view port rectangle.
cc.view.getVisibleSize();//Returns the visible area size of the view port.
cc.view.getVisibleSizeInPixel();//Returns the visible area size of the view port.
cc.view.getDesignResolutionSize();//Returns the designed size for the view. Default resolution size is the same
我在canvas节点的设计分辨率是480x800，然后用以下代码在Chrome中进行测试：
cc.log("cc.director.getVisibleSize:",cc.director.getVisibleSize().toString());
cc.log("cc.director.getWinSize:",cc.director.getWinSize().toString());
cc.log("cc.director.getWinSizeInPixels:",cc.director.getWinSizeInPixels().toString());
cc.log("cc.view.getFrameSize:",cc.view.getFrameSize().toString());
cc.log("cc.view.getViewPortRect:",cc.view.getViewPortRect().toString());
cc.log("cc.view.getVisibleSize:",cc.view.getVisibleSize().toString());
cc.log("cc.view.getVisibleSizeInPixel:",cc.view.getVisibleSizeInPixel().toString());
cc.log("cc.view.getDesignResolutionSize:",cc.view.getDesignResolutionSize().toString());
得到数据如下：
=============Default=============
cc.director.getVisibleSize: (480.00, 800.00)
cc.director.getWinSize: (480.00, 800.00)
cc.director.getWinSizeInPixels: (480.00, 800.00)

cc.view.getFrameSize: (414.00, 736.00)
cc.view.getViewPortRect: (0.00, 0.00, 414.00, 736.00)
cc.view.getVisibleSize: (450.00, 800.00)
cc.view.getVisibleSizeInPixel: (414.00, 736.00)
cc.view.getDesignResolutionSize: (480.00, 800.00)
截图工具测量大小: (414.00, 736.00)
1.cc.director.getVisibleSize();//获取运行场景的可见大小
不理解，它和我用截图工具测量的不一样啊？？
2.cc.director.getWinSize();//获取视图的大小，以点为单位
cc.director.getWinSizeInPixels();//获取视图大小，以像素为单位
不理解，它们两个数值都一样啊，你这里的视图大小指的什么？？？？
3.cc.view.getFrameSize();//Returns the frame size of the view
不理解，???
4.cc.view.getViewPortRect();//Returns the view port rectangle.
不理解，???
5.cc.view.getVisibleSize();//Returns the visible area size of the view port.
cc.view.getVisibleSizeInPixel();//Returns the visible area size of the view port.
了解，也只有这一个和截图大小一致，两VisibleSize与VisibleSizeInPixel这两个不一样，单位不同
6.cc.view.getDesignResolutionSize();//Returns the designed size for the view. Default resolution size is the same
了解，和场景中Canvas设置的一样
