remove的只有Armature的动画数据。&还需要清理图片帧，图片缓存（记得按我说的顺序来）

CCArmature动画释放&&&
释放摸一个动画，按照fancong 童鞋的方法！armature-&removeFromParent(); armature-&release()&&&& CCArmatureDataManager::sharedArmatureDataManager()-&removeArmatureFileInfo(&xxxx.xml&) ; &&&&CCSpriteFrameCache::sharedSpriteFrameCache()-&removeSpriteFramesFromFile(&xxx.plist&); &&&& CCTextureCache::sharedTextureCache()-&removeTextureForKey(&xxx.png&); 完全没有感觉出内存释放啊！2.2.1版本，新的版本呢？

同问啊 移除CCArmature的缓存到底是怎么个流程 是需要每一个动画对象都依次removeArmatureFileInfo()&&removeSpriteFramesFromFile() removeTextureForKey() 然后再purge() ? 异步加载的资源也能这样移除掉吗？

扫一扫 浏览移动版我忘了我这篇测试的主要目的是干啥了...。
就算往项目上靠靠吧，我项目里面要用到CCArmature这个，给这个实现单指拖拽，双指缩放功能。
新建类MyArmature，和MySprite类似，如下：

draw方法是测试用的，因为在测试时发现boundingBox的位置不准，所以把它描绘出来看看。后面再说这个吧。
HelloWorld的init方法
bool HelloWorld::init()
if ( !CCLayer::init() )
return false;
CCArmatureDataManager::sharedArmatureDataManager()-&addArmatureFileInfo("run.png", "run.plist", "run.xml");//加载动画资源
MyArmature* armature = MyArmature::create("run",1);
armature-&setPosition(VisibleRect::center());
armature-&setScale(2.0f);
this-&addChild(armature,0);
MySprite* pSprite2 = MySprite::create("Icon-114.png",2);//优先级数值越小越优先响应
pSprite2-&setPosition(VisibleRect::center());
pSprite2-&setScale(2.0f);
this-&addChild(pSprite2, 1);
MySprite* pSprite = MySprite::create("HelloWorld.png",0);
pSprite-&setPosition(VisibleRect::center());
this-&addChild(pSprite, 1);
return true;
CCArmature是 cocos2dx 扩展包里的东西，别忘了下面两行
#include "cocos-ext.h"
using namespace cocos2d::
然后就应该可以看看效果了。
是不是发现boundingBox不是想得那么回事？因为Armature中有子Armature的关系吧，我猜的。
在论坛发帖问了，还没得到回复，自己尝试hack了一下源码，没想到啊，还好使了。。。
修改CCArmature::boundingBox如下：
CCRect CCArmature::boundingBox()
float minx, miny, maxx, maxy = 0;
bool first = true;
CCRect boundingBox = CCRectMake(0, 0, 0, 0);
CCObject *object = NULL;
CCARRAY_FOREACH(m_pChildren, object)
if (CCBone *bone = dynamic_cast&CCBone *&(object))
CCArmature* child = bone-&getChildArmature();
//CCRect r = bone-&getDisplayManager()-&getBoundingBox();//hack by HanHongmin
if(child!=NULL){
r = child-&boundingBox();
r = bone-&getDisplayManager()-&getBoundingBox();
//hack finish
minx = r.getMinX();
miny = r.getMinY();
maxx = r.getMaxX();
maxy = r.getMaxY();
first = false;
minx = r.getMinX() & boundingBox.getMinX() ? r.getMinX() : boundingBox.getMinX();
miny = r.getMinY() & boundingBox.getMinY() ? r.getMinY() : boundingBox.getMinY();
maxx = r.getMaxX() & boundingBox.getMaxX() ? r.getMaxX() : boundingBox.getMaxX();
maxy = r.getMaxY() & boundingBox.getMaxY() ? r.getMaxY() : boundingBox.getMaxY();
boundingBox.setRect(minx, miny, maxx - minx, maxy - miny);
return CCRectApplyAffineTransform(boundingBox, nodeToParentTransform());
运行之，看看吧。
改的对不对我不知道哈，反正跟我要的效果差不多了。
等着看论坛帖子下文吧：
恩，现在两个自定义类了，可能大家早就发现了，能够提取出来公共代码。
虽然复制粘贴不麻烦，但是我想，大多数程序员都应该有代码洁癖吧。。。
各位自行搞一搞吧，我尝试了一下不会弄T_T，谁弄好了告诉我一声。
还有一点，如果涉及到x轴Y轴单向翻转的话，缩放哪里要注意，X，Y要分开。
setScale方法会把scaleX和scaleY都设置了，相当于调用了setScaleX和setScaleY。
