为啥CCArmatureDataManager这个不能用呢，我只是新建了一个项目，然后加了下面几行代码
cocos2d::extension::CCArmatureDataManager::sharedArmatureDataManager()->addArmatureFileInfo(“Cowboy0.png”,
“Cowboy0.plist”,
“Cowboy.json”);
cocos2d::extension::CCArmature *armature = NULL;
armature = cocos2d::extension::CCArmature::create(“Cowboy”);
armature->getAnimation()->playByIndex(0);
armature->setScale(0.2f);
armature->setPosition(ccp(150,150));
addChild(armature);
求解。。
