（基于cocos2dx 2.2.2）
如果很多图片很小或常用，可以使用CCSpriteFrameCache,来避免资源被反复加载。
（注：对于plist，我这里使用的是一个免费的工具，SpritePacker，http://spritepacker.kernys.net）
如：CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("basetank.plist");

这样，就可以完成一组图片资源加载。
CCSprite * p1Pic = CCSprite::createWithSpriteFrameName(“basetank_up.png”);
p1Pic->setPosition(GetPosition(pPlayerLayer, "Player1"));
p1Pic->setAnchorPoint(ccp(0, 0));
this->addChild(p1Pic);
如需更换图片，
p1Pic
->setDisplayFrame(CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("basetank_right.png"));
这里的作用相当于是把tank向右转
