附: preloading.plist

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"/><plist version="1.0">  <dict>    <!-- .png 图片预加载 -->    <key>png</key>    <dict>      <key>1</key>      <string>pngName</string>    </dict>    <!-- .plist 图片预加载 -->    <key>plist</key>    <dict>      <key>1</key>      <string>plistName</string>    </dict>    <!-- .pvr.ccz 图片预加载 -->    <key>pvr_ccz</key>    <dict>      <key>1</key>      <string>pvr_cczName</string>    </dict>    <!-- .ExportJson 骨骼动画预加载 -->    <key>ExportJson</key>    <dict>      <key>1</key>      <string>jsonName</string>    </dict>  </dict></plist> 

刚开始预加载plist的回调是这样的

void ResourceManager::plistImageAsyncCallback( cocos2d::Texture2D* texture_ ){    log("AsyncLoadCallBack\t\t%s.plist", m_vPlist[m_iPlistNum].c_str());    SpriteFrameCache::getInstance()->addSpriteFramesWithFile(m_vPlist[m_iPlistNum]+".plist", m_vPlist[m_iPlistNum]+".png");    ++m_iPlistNum;    ++m_iLoadFileNum;    //此处可以设置加载进度百分比    if (m_iLoadFileNum >= m_iTotalFileNum)    {        //此处可以跳转场景    }}

但是会出现资源匹配错乱的问题, 具体原因不明, 也不想去查了.
