第1种方式
第2种方式
1.
function OneArmLayer:getPropNodeByDictId(dictId) local propNode = PropIconNode.GetOrCreate() PropIconNode.setInfoProp( propNode, dictId ) PropIconNode.showTips( propNode, true ) PropIconNode.setPropNum( propNode, 1 ) PropIconNode.setPropNumLabelVisible(propNode, false) -- propNode:setScale(0.6) return propNodeend
2.
-- 按名字获得节点function NodePool:getNode( nodeName )local node_list = self:_getOrCreateNodeList( nodeName ) local size = table.maxn( node_list ) for i = 1, size do local node = node_list[ i ]if node:getReferenceCount( ) == 1 thenreturn nodeendendreturn self:_createNode( node_list, nodeName )end
3.
function NodePool:_getOrCreateNodeList( nodeName )local node_list = self.pool_list[ nodeName ]if not node_list thennode_list = { }self.pool_list[ nodeName ] = node_listend return node_listend4.function NodePool:_createNode( node_list, nodeName )local node = UI.nodeFromCSB( nodeName )if node thennode:retain( )table.insert( node_list, node )endreturn nodeend5.
function UI.nodeFromCSB( uiname, belongNode ) cclog(" cc.CSLoader:createNode %s", uiname ) local node = cc.CSLoader:createNode( uiname ) node:setAnchorPoint( 0.5,0.5 ) node:setPosition( cc.p( 0, 0 ) ) node:setName( uiname ) if belongNode == nil then belongNode = node end if belongNode ~= nil then local nodeMap = dyt.Cocos2dUtils:seekBindingNodeList( node ) for name, node in pairs( nodeMap ) do belongNode[ name ] = node end end return nodeend第一种方式在addChild之前，引用计数都是1，因此propNode1 propNode2 propNode3指向同一个节点。
第二种方式：引用计数是2，因此重新缓存起来了，得到的是不同的节点。

A，B都是用nodeName叫: coin.csd 来创建的,当然创建的同时addChild了一下，此时引用计数为2
然后A removeParent后,引用计数为1， B依然为2.
这时候再去用coin.csb去创建节点，那么检测到引用计数为2，这时，就会直接返回这个A节点，不用重新创建对象了。因为创建new个对象，加载csb相对耗时。想下缓存池的意思就是：将已经用过的东西缓存起来，下次再次用到时，不用重复创建。
