CCSpriteFrame
精灵帧
CCTexture2D 将被用于CCSprite
默认的构造方法
通过 图片纹理+纹理上的矩形来创建
或通过 图片纹理+纹理上的矩形+是否旋转+偏移坐标+真实size
这里简单讲下
是否旋转
为了节省图片空间 图片将会被旋转90度
偏移坐标+真实size
为了节省图片空间 原始图片周围透明区域将被trim

Detailed Description
A CCSpriteFrame has:
texture: A CCTexture2D that will be used by the CCSprite
rectangle: A rectangle of the texture
You can modify the frame of a CCSprite by doing:
CCSpriteFrame *frame = CCSpriteFrame::frameWithTexture(texture, rect, offset); sprite->setDisplayFrame(frame);
